Trichocereus litoralis – Echinopsis chiloensis ssp. litoralis

Trichocereus litoralis – Echinopsis chiloensis ssp. litoralis

This beautiful Trichocereus species is definitely closely related to Trichocereus chiloensis and the current taxonomy is treating it as a variety or subspecies to it. Trichocereus litoralis always was a problematic species because there are so many intermediate forms between Trichocereus chiloensis and Trichocereus litoralis that it is extremely difficult to draw the line somewhere. While some treat it as part of Trichocereus chiloensis, some others disagree and treat it as a separate species. Personally, I think that the whole group of plants surrounding Trichocereus chiloensis is very variable and we should simply respect that plants can be related to each other and at the same time, look a little bit different. The species is also very closely related to Trichocereus skottsbergii, which I also regard as a variety of Trichocereus chiloensis/Echinopsis chiloensis.

Origin of E.litoralis:

Chile. Growing mostly around the coast line. Coquimbo

Synonyms of T.litoralis:

Echinopsis litoralis, Cereus litoralis, Trichocereus chiloensis var. litoralis, Trichocereus chilensis var. litoralis, Cereus chilensis,

The type location is in Zapallar, north of Valparaiso near the coast of Chile. The species is widely distributed all across the coast up to Los Vilos. The many radial spines are needle-like, while the middle spines are pretty strong and thick and up to 3 cm long. It has 9-28 radial spines and 3-6 middle spines.

Trichocereus chiloensis ssp. litoralis gets between 1-2 meters tall. It has a very dark green color and and a maximum diameter of 10-15 centimeters.

Ribs of Echinopsis chiloensis ssp.litoralis:

15-22, areoles approximately 1-2 centimeters apart of each other.

Flowers of Trichocereus litoralis:

Trichocereus litoralis has a white flower, which is extremely similar to the one on Trichocereus chiloensis. The flowers are up to 15 centimeters long, which is on the lower end of the scale for Trichocerei.

Fruit of E.litoralis:

Round, dark green. Up to 5 Centimeters in diameter

Trichocereus tarijensis / Echinopsis tarijensis

Trichocereus tarijensis / Echinopsis tarijensis

The species trichocereus tarijensis, also known as Echinopsis tarijensis or Trichocereus poco, is a columnar cactus. Today it is separated through various subspecies that all count as part of Trichoereus tarijensis.

Currently valid names

Echinopsis tarijensis +

Echinopsis tarijensis ssp. herzogiana / Trichocereus herzogianus

Echinopsis tarijensis ssp. tarijensis / Trichocereus tarijensis

Echinopsis tarijensis ssp. totorensis / Trichocereus totorensis

In addition the species Trichocereus poco / Echinopsis poco is seen as part of Trichocereus tarijensis as well.

Trichocereus tarijensis is a massive and spiny Trichocereus species. Its many forms make it difficult to clearly separate some regional forms, which is why the whole complex should rather be seen as a group of very similar regional forms that ll belong to the same species. It is partially synonymous with trichocereus totorensis, Trichocereus bertramianus and Trichocereus poco.

Type locality

The type locality is Tarija in Bolivia and it grows throughout southwest and south Bolivia, parts of Argentina and the Andes.

Synonyms:

Trichocereus Poco, Helianthocereus poco, Cereus tarijensis, Lobivia formosa ssp. tarijensis, Trichocereus herzogiana, Helianthocereus herzogiana, Helianthocereus tarijensis, Trichocereus totorensis, Helianthocereus totorensis, Trichocereus narvaecensis, Trichocereus narvaezensis, Trichocereus bertramianus, Echinopsis bertramiana, Echinopsis narvaecensis, Trichocereus orurensis, Echinopsis orurensis, etc.

Description of T.tarijensis

Typically, Trichocereus tarijensis has 15-25 ribs, can get up to 40 centimeters in diameter with spines that can get 1-10 centimeters long. Spines yellowish in color. 1-5 Middle thorns and up to 45 radial thorns. The spines are usually long and are pointing downwards, what gives Trichocereus tarijensis a great protection against anything trying to eat it. The diameter can reach a stunning 40-50 centimeters. Young specimens are very similar to Trichocereus pasacana, but are a lot more spiny, especially later on.

Flowers:

Red to pink to milky white and over 10 centimeters in lenght. Green fruits, up to 5 centimeters in lenght. 3 centimeters in diameter. There is great variation within the look of the flowers and while some can be more rose-colored, some others look more reddish.

And also the rest of the plant can be greatly variable, which is the reason that this species caused a lot of confusion due to numerous descriptions of plants that somehow seem to belong into the same complex. A lot of the species inside Backeberg´s genus “Helianthocereus” belong into the Tarijensis group, that now consists of a handful of subspecies, instead of varieties. That is a fine but very important difference and I tend to agree that this is exactly the right way to classify this group of impressive giants that can be found all over the Andes.

Young specimen of Trichocereus poco, also known as Trichocereus tarijensis v. poco. You can perfectly see the similarity to Trichocereus Pasacana and Terscheckii. The plant is a lot more spiny though and that´s exactly how you can differentiate it.

Trichocereus Herzogianus ssp Totorensis367This plant was labeled Trichocereus Herzogianus ssp. Totorensis. It is also the same plant called Trichocereus Totorensis, Helianthocereus Totorensis or the new name Trichocereus Tarijensis ssp. Totorensis.

Trichocereus thelegonus / Echinopsis thelegona Friedrich & Rowley

Trichocereus thelegonus, also known as Echinopsis thelegona, is a columnar Trichocereus species from Argentina.

Trichocereus thelegonus / Echinopsis thelegona Friedrich & Rowley 1
Pic: Noah Reams

Origin:

Argentina, Tucumán, Salta, 5500-1100 meters altitude

Synonyms:

Trichocereus thelegona, Trichocereus thelegonus, Echinopsis thelegonus, Echinopsis thelegona, Cereus thelegona, Cereus thelegonus

Trichocereus thelegonus is a branchy & creeping cactus that only produces a handful of shoots. It can reach a maximal height of approximately 2.2 meters and can get up to 10 centimeters in diameter. But that´s only the case on very old plants and most of them get 6 – 8 cm in diameter. The plant has 12-13 ribs and is characterized by its very dominant areoles that sit in top of some extremely hexagonal warts. It´s look is very typical and once you got used to the plant, it´s very hard to overlook or misidentify it.

Trichocerus thelegonus has rounded areoles and yellow to dark/brown spines. There also are regional types that rather have a reddish spine color instead of the brown one. Old growth tends to change its color to a more blackish tone, similar to how it can be observed on Trichocereus cuzcoensis. That said, both are really not very similar and this interesting plant from Argentina rather resembles a hanging basket cactus, than a classic columnar. Tr. thelegonus / Echinopsis thelegona usually has one and, in some very rare cases, two middle spines and between 5-8 radial spines that can reach up to 2,5 centimeters in length.

FLOWER:

Trichocereus thelegonus is a night flowering species, with flowers than can stay open until the early morning. The flower is white and gets up to 22 centimeters long and I measured a staggering 17 centimeters in diameter.
Apart from the size, the flower is very beautiful and has a wonderful scent!

Fruits:

The fruits of Trichocereus thelegonus are round and have reddish brown hairs. The fruits are reddish and can reach 6 centimeters in diameter. It does not produce as many seeds as other plants from the same genus. Trichocereus thelegonus / Echinopsis thelegona is self-sterile and it needs pollen from other plants to produce seed.

Trichocereus thelegonus cristata / crest:

There also is a crested clone of this plant that is extremely cool and resembles a monstrose Cereus. I´ve been lookingf or this crest for years, but wasn´t able to find one yet. Luckily, there are some pics from a Botanical garden:

Buy seeds or cuttings of Trichocereus thelegonus / For sale:

This species is kinda rare, but I sometimes get viable seeds of Trichocereus thelegonus. The problem isn´t that there aren´t any seeds available; but most of the ones that were, did not germinate. I am working on putting the type in my shop and if you want to be up to date about my fresh seeds, please subscribe to my newsletter at: trichocereus.net/newsletter.

Trichocereus angelesii / Echinopsis angelesii or angelesiae

Trichocereus angelesii / Echinopsis angelesii or angelesiae

Trichocereus angelesii, also known as Echinopsis angelesii or Echinopsis angelesiae, was originally described by Friedrich Ritter as a white flowering variety of Trichocereus strigosus / Trichocereus strigonus, until Kiesling publicized it under the name Trichocereus angelesii.

The flower of Trichocereus angelesii

The flower of Echinopsis angelesii is white and 12-24 centimeters long. Trichocereus angelesii is a day flowering / diurnal species with clear visual similarity to Trichocereus strigonus. The spines, fruits and seeds are pretty much indistinguishable from the ones of Trichocereus strigosus, which makes it nearly impossible to identify the plant unless you find it at the original type location. Trichocereus angelesii, aka Echinopsis angelesii, usually has 14-22 ribs . In comparison to this, Trichocereus huascha has 12-15 ribs.

The typus location is Famatima in the provence La Rioja, what makes it likely that it is synonymous with the commercial name Trichocereus famatinensis. It is also closely related to the plant that Ritter called Trichocereus callianthus. This plant was originally sold by Ritter as FR999, which was still labeled as Trichocereus huascha back then.

Kiesling´s description gives Darwinia in Argentina as the typus location and it´s not clear whether or not those plants were actually the same.

Buy Trichocereus angelesii / Buy seeds of T. angelesii

It´s a rare species that you only get rarely, but classic Kaktus nurseries like Kakteen Haage or Uhlig Kakteen might have some of them available. If you don’t have the chance to collect them at one of the aforementioned locations, you will probably not run into it very oftenly. There are also some older plants that you can find on the commercial market, and these are usually labeled as T. huascha or Trichocereus strigonus. White flowering Trichocereus huascha might very well be a mislabeled Trichocereus angelesii.

Trichocereus werdermannianus / Echinopsis werdermanniana

Trichocereus werdermannianus / Echinopsis werdermanniana

Trichocereus werdermannianus, also known as Echinopsis werdermanniana, is a columnar Trichocereus species from Bolivia. It is a close relative of Trichocereus terscheckii and I consider it an intermediate species between the large Andean Trichoereus terscheckii and Trichocereus taquimbalensis.

Original name:

Trichocereus werdermannianus Backeberg & Knuth, Kaktus ABC

Trichocereus werdermannianus is an old name that is debatable because it is so genetically close to Trichocereus terscheckii and might as well be seen as a regional form of it. The plant was discovered and described by Curt Backeberg, who named it after the German Botanist Erich Werdermann.

Trichocereus werdermannianus is a species that is difficult to identify, and its similarity to Trichocereus terscheckii make it difficult to distinguish it from it.

Apart from T.werdermannianus being mislabeled as T. terscheckii, they are also often labeled as Trichocereus taquimbalensis or tacaquirensis. For example, there are a few seed & plant distributors that sell cacti labeled Trichocereus werdermannianus, and the plants we grew from them ended up being all kinds of species. Trichocereus werdermannianus was sold as Trichocereus terscheckii, Trichocereus taquimbalensis, Trichocereus pasacana, Trichocereus peruvianus and Trichocereus macrogonus.

A very constant trait in all Trichocereus werdermannianus plants is the dark green to blue gray green color of epidermis, that is very typical for this species. Most if not all specimens I ever saw had a very dark green epidermis and a spination that looks like a mix of Trichocereus taquimbalensis and Trichocereus terscheckii.

I included the Description from Backeberg´s Book below. Backeberg acknowledges Trichocereus werdermannianus´genetic proximity to Trichocereus terscheckii and Trichocereus validus, but mentions that its flowers usually emerge from the top of the plant, while the two species mentioned before would have flowers that appear at lower regions of the plants body. Based on these observations, we think that it should merely count as a form or variety of Trichocereus terscheckii. That is if we even go so far to split a species up based on such criteria.

Flowers of Trichocereus werdermannianus:

White, flowering from the apex, flowers similar to the flowers of E.terscheckii.

The trees reach a size of 5 meters and a maximum diameter of 65 centimeters. Young plants have 10+ ribs while adult specimens can have 14+ ribs. The plant has ten spines that are between 5 and 10 centimeters long, color between yellow and yellowish brown. Many flowers that arise around the apex of the plant. The flowers can get up to 22 centimeters long, but the whole complex is very variable in this regard. The fruit is up to 4 centimeters in diameter and has many white or black hairs.

Trichoecreus werdermannianus seeds

The seeds of this species are usually 1,4 mm large, but that is also influenced by other factors such as region, plants that grow in direct neighborhood.

Origin of E.werdermanniana:

Bolivia, the type location is in the Charcoma Valley east of Tupiza. However, the species is also present around Potosi. Backeberg suspected that Trichocereus taquimbalensis from the region around those aforementioned locations is actually Trichocereus werdermannianus. It is obviously related to Trichocereus taquimbalensis, but there are substantial differences between these two species.

The first Two Pictures are in Fact the plant that Backeberg understood as Trichocereus werdermannianus. Pictures from the unspeakable Thunderhorse! 😉 In Front on the lower left: True validus! Please note that some pics on this page actually show plants labeled Trichocereus werdermannianus, but get very close to Trichocereus taquimbalensis.  It´s probably not that easy to draw a firm line between these two species sometimes.

The three pics above show seedlings that were raised from KK1094 Trichocereus werdermannianus seed. Please note that those seedlings actually ended up being Trichocereus taquimbalensis var. wilkae instead
Knize used this number for two plants. First, Trichocereus giganteus and then Trichocereus werdermannianus. Maybe he wasn’t sure about the ID, called it Tr. giganteus and changed it to Tr. werdermannianus later on. Both plants are collected in Otavi, Bolivia. Giganteus at 3200 Meters and Werdermannianus at 3500m.  Pics: MUTANT.

I own a Trichocereus giganteus KK1094, which ended up being a completely typical Trichocereus werdermannianus.

Orignal description of Curt Backeberg in German:

Trichocereus werdermannianus Backb g. — Backeberg & Knuth, Kaktus-
ABC, 206, 412. 1935
Bis 5 m hoch; Stamm bis 1 m hoch und bis 60 cm ∅; Rippen ca. 10, später 14

kaum unterschieden, bis 7 cm lang, gelblich bis bräunlichgelb bzw. hornfarbig;
Bl., wenn zahlreich vorhanden, ± kranzförmig um den Scheitel oder scheitelnah;
bis 20 cm lang; Gr. weiß, kaum die Staubb. überragend; N. 15—19; Fr. kugelig,
3,5 cm ∅, lange, aber nicht sehr zahlreiche schwarze und weiße Haare tragend;
S. 1,3 mm groß, mützenartig, rauh punktiert. — B o l i v i e n (von mir, als Typort,
im Charcoma-Tal, östlich von Tupiza gefunden, von Cardenas auch in den
trockenen interandinen Tälern der Departements Potosi und Chuquisaca, auf
ca. 2600 m Durchschnittshöhe der Vorkommen) (Abb. 1054—1055). Während Trichocereus validus und T. terscheckii seitlich ± weit herab blühen,
ist T. werdermannianus durch seine nur hochsitzenden Bl. eindeutig unterschieden.
Sie alle scheinen nach den viel längeren Bl. und der sich nie verändernden
Stachelbildung an den Spitzen großer Pflanzen echt trichocereoide Riesenformen
zu sein, die (zum Teil) auch nachts geöffnete Bl. zeigen, wie ich zumindest an zwei
Arten beobachtete.
„Trichocereus pasacana“ dagegen scheint die größten Formen der Helianthocereus-
Formengruppe zu bilden, mit kürzeren Bl., gedrungeneren Röhren und an
alten Exemplaren bzw. solchen an hohen Standorten mit borstenartig elastischen
St., wie sie den Hochlands-Helianthocereus-Arten eigentümlich sind. Ich habe
daher Trichocereus pasacana auch zu Helianthocereus gestellt. Er ist zudem Tagblüher, soweit bekannt.

Trichocereus validus / Echinopsis valida

Trichocereus Validus Monv. aka Echinopsis Valida

Trichocereus validus, also known as Echinopsis valida, is a columnar cactus that´s closely related to Trichocereus terscheckii. I consider it a form, variety or subspecies of Echinopsis terscheckii. Which one´s exactly the case will have to be decided by DNA testing .

Synonyms:

Cereus validissimus, Echinopsis valida, Echinopsis validus, Echinopsis robbinsoniana, Cereus forbesii, Trichocereus forbesii, cereus forbesii, Echinopsis rhodotricha, Trichocereus rhodotricha, Trichocereus terscheckii, Trichocereus terscheckii

Trichocereus validus grows like a tree and can get up to 40 centimeters in diameter. It doesnt get quite as thick as Trichocereus terscheckii, which is a close relative of it. The origin of Trichocereus validus is not know, was but it was probably Bolivia. In Bolivia, there are various Andean Trichocereus species from the Trichocereus terscheckii complex that this species could have come from. There´s populations of Trichocereus werdermannianus and Trichocereus tacaquirensis, which are both very similar in appearance. My personal impression is that Trichocereus validus is just one particular type of Trichocereus terscheckii.

Ribs:

10-12. Older specimens have a higher rib count, which is pretty typical. There are very little spines around the upper half of the body, what makes it look like a nearly spineless version of Trichocereus terscheckii.

The areoles are 2,5 – 3,5 centimeters apart of each other. 5-10 radial spines that are up to 4 centimeters long with a very typical outwards pointing spine, which is actually the lowest on the areole. In addition, Trichocereus Validus has approximately 1-2 middle spines. 5-10 centimeters long.  Spines have a very small but visible rounded spine base. The spine color is yellow, similar to the one on Trichocereus Terscheckii.

Flower of Trichocereus validus:

White. Similar to Trichocereus terscheckii and between 10-15 centimeters long and up to 15 centimeters in diameter. Gray-brown hairs on the flower and white petals.

Fruit of T.validus:

Round fruit with wool & hairs on top of it.

The original description of Trichoecreus validus was written after a bad photo, and there was no flower photo or description originally. However, a flower description could be made eventually after a plant that grew in the Botanical Garden in De Cedres and the photos we saw did show a very close relative of Trichocereus terscheckii. While it has pretty unique spination, it´s still pretty obvious that the plant was some variety of Trichocereus terscheckii.

Sources for Seed & live cuttings of Trichocereus validus:

I am very proud that some of the members from our SAB forum were able to relocate this long lost plant in Australia and make it somewhat available. There were a few growers that received cuttings of this remarkable plant and we sometimes have cuttings available in our Trichocereus Facebook Group.

Another breeder who offers some seeds of Trichocereus validus is Misplant.net! He has a plant that roughly belongs to the same complex, but which isn´t quite the same mother plant to make a couple crosses every year and you can buy seed through his Seed store on Misplant! Misplant´s Trichocereus validus belongs somewhere in the relationship of it and Trichocereus uyupampensis, another rare Trichocereus that is considered (by some) to be synonymous with Trichocereus validus. Whether or not this is the case is currently not clear.

In Australia,  this plant was made available through the Fields Family and collection, who owned two large mother plants before the collection was donated to the Melbourne Botanical Garden.  In addition, you can get seeds of Trichocereus validus from Sacred Succulents but I haven’t seen their mother plant yet. I will add new sources for this plant in this article but at the moment, I do not know more.

Cultivation & frost tenderness of E.valida:

Trichocereus validus is very similar to Trichocereus terscheckii and everything I wrote about the cultivation of it applies here too. These large Andean giants can take slight night frosts, but it should not go over -5° to -7° Celsius or it will get dangerous. The plants need to be dry and the average minimum temperature should be around 10° Celsius during the cold winter months. Trichocereus validus is extremely thick and it needs a large, deep pot if you ever want to see it flowering.

Trichocereus validus Echinopsis valida Robbinsoniana Backeberg

trichocereus validus flower Echinopsis valida Robbinsoniana Backeberg

The Plant here was found on ebay and has many similarities to Trichocereus Validus. Chances are, it´s just some Terscheckii with a similar Spination. But since Trichocereus Validus is most likely nothing else than some Terscheckii Variety it´s not really possible to clear this up.

Now the next Plant is really interesting. It is what many growers call the FIELDS Validus. It grows on a private property in Australia and the Owner originally bought some Seeds of Friedrich Ritters Collection of Trichocereus Validus and grow it out into a gigantic Monster of Awesomeness! The Plant is identical with the Plant shown in Backebergs Cactaceae and IS most likely the Terscheckii Variety that is known as Trichocereus Validus.

Rodni Kisar

This Plant grows in the Huntington Botanical Garden and is labeled Echinopsis Robinsoniana . It is actually the plant that came to fame as Trichocereus Validus. It´s probably a variety of Trichocereus Terscheckii and chances are that there are seeds labeled as that available on the market. So whenever you encounter Echinopsis Robinsoniana or Terscheckii varieties from Bolivia, it might be the plant that was once called Trichocereus Validus. I am beyond doubt that Trichocereus Validus didn´t suddenly cease to exist in cultivation but simply carries another label these days.

Echinopsis robinsoniana Numen Nudum (Trichocereus validus)

This Plant is labelled Echinopsis robinsoniana and looks very much look the Trichocereus validus pictured in Backebergs CACTACEAE. Personally, I am absolutely sure that Echinopsis robinsoniana is just a synonym for Trichocereus validus. This plant grows in the Huntington Botanical Garden, but this species has not been found outside the Botanical Garden and most plants that are found in the wild are identified as Trichocereus terscheckii or one of its associated species. It is definitely possible to come across this plant on the botanical market, labeled as Trichocereus terscheckii, Trichocereus werdermannianus, trichocereus validus etc. There are countless forms and intermediates that belong to this complex and there is a great amount of variety within the large Andean Trichocereus species. Trichocereus pasacana is another closely related species.

Trichocereus tarmaensis / Echinopsis tarmaensis

Trichocereus tarmaensis Rauh & Backeberg – Deser. Cact. Nov. 20. 1956

Trichocereus tarmaensis is a close relative of Trichocereus cuzcoensis that was described as a separate species. There are various differences between Trichocereus cuzcoensis and Trichocereus tarmaensis, and some forms of Trichocereus knuthianus are considered to be synonymous with Trichocereus tarmaensis as well.

Echinopsis tarmaensis Tarma Trichocereus tarmaensis

Trichocereus tarmaensis reaches a size of 2 meters and is pupping from the base. It has 7-9 ribs that are approximately 2 centimeters wide, rounded at the top and with very distinct V-notches above the areoles. The areoles are approx. 2-2,5 centimeters apart with a diameter of 9 millimeters. Young growth areoles have a very fine brown wool that changes it´s color to a darker brown. It has 3-6 radial spines that are between 1 and 3 cm long. It often has one very large downward pointing spine that is up to 10 centimeters long. The plant usually has one of those middle spines. Old spine growth changes its color very soon to a gray, similar to what we know from Trichocereus cuzcoensis.

Flower of E.tarmaensis:

White, very similar or identical to some of the spiny forms of Trichocereus cuzcoensis or  Trichocereus peruvianus. The tube has brown hairs and the fruit reaches a maximum diameter of 5 centimeters.

Type location:

Central peru, Tarma in Peru at around 3000 meters.

Trichocereus tarmaensis looks very similar to Trichocereus tulhyacensis and both species are hard to distinguish if do not have the luck to observe them during the flowering phase . The flower of Trichocereus tulhuyacensis is pink, which is something that does not apply to any other Trichocereus species from this complex. If your Trichocereus has a reddish to pink flower, it´s not Trichocereus tarmaensis but Trichocereus tulhuyacensis or another close relative. Both Trichocereus tarmaensis and Trichocereus tulhuayacensis are very rare and mislabeled anyways. Karel Knize is selling seed of this type under the name KK2148 Trichocereus tarmaensis .

When looking at this pic, it gets obvious that this type is VERY similar to some types of Trichocereus cuzcoensis, and even has similarities to a KK242. I do not think that specimens of KK2148  could be recognized as such without knowing the label. They are simply synonymous with some types of Trichocereus cuzcoensis. This species grows at around 3000 meters altitude.

Trichocereus grandiflorus / rowleyi (Echinopsis grandiflora)

Trichocereus grandiflorus / rowleyi (Echinopsis grandiflora)

Trichocereus grandiflorus is a cactus from the genus Trichocereus. Its status is highly questionable as a correct species and the opinions are as varied as the names it carried. Joel Lodé has listed Trichocereus grandiflorus as Trichocereus rowleyi right now, while Anderson listed it as a synonym of Echinopsis huascha in his Cactus Lexicon. Please note that some people also refer to this plant as Echinopsis grandiflora, but this name is also used by Echinopsis eyriesii v. grandiflora and the older name has priority.

Synonyms of Trichocereus grandiflorus:

Lobivia grandiflora, Lobivia grandiflorus, Helianthocereus grandiflora, Helianthocereus grandiflorus, Helianthocereus huascha, Trichocereus rowleyi, Echinopsis huascha

Trichocereus grandiflorus was moved around between the genera  a lot in the past. It is genetically close to both Lobivia and Soehrensia, which is why it was sometimes included there. Friedrich et al. listed it as Echinopsis grandiflora. Anderson then listed it as a synonym to Echinopsis calochlora in his CACTUS LEXICON. Joel Lodé lists it as Trichocereus rowleyi. Schlumpberger lists it as Soehrensia grandiflora (Schlumpberger).

T.grandiflorus Flower:

The flowers of Trichocereus grandiflorus are often red and/or show various variations of red flowers. There are many hybrids, which is why the flower color is relatively unrelaible. There also are versions of flowers that are white in color and between 15-25 Centimeters in size. The tube is usually very hairy, but there are countless hybrids with all kinds of flower colors available on the open market.

Origin of Trichocereus grandiflorus:

Argentina, especially around Catamarca. The original description refers to a plant from a private collection and it is suspected that Trichocereus grandiflorus is extremely close to Trichocereus huascha and might even be part of this species.

The original description as Lobivia grandiflora came from Britton & Rose. Because of that, the plant was labeled as a Lobivia in most classic cactus literature. In addition, the title “Grandiflorus”, which roughly means “Large Flower” makes a lot of sense because most Lobivias usually have smaller flowers. The large flower size for a Lobivia shows that it is not a very normal Lobivia either. The collector Fric, who labeled it Chamaecereus giganteus (same principle because most Chamaecereus are tiny Lobivia), originally introduced the plant into the market, but since it was so different from Chamaecereus, this did not last long. Backeberg wanted to put it in his own problematic Genus Helianthocereus due to the diurnal flowers, but this flawed system was not adapted. Eventually, the plant ended up in Trichocereus, where it was until the restructuring made by Friedrich et al.

Cultivation of Trichocereus rowleyi (ex GF):

Trichocereus grandiflorus is a very hardy plant that can grow a lot during just one growing season if watered accordingly. The plant is able to tolerate some light frost but I would not recommend trying it out to the limit. I keep them at around 10° Celsius during the wintertime in a bright and well-ventilated room. I do not water them during the wintertime and only start watering again in March.

Buy Trichocereus grandiflorus / Seeds or Plants:

This plant is available every now on then on marketplace sites like Ebay or Amazon. In addition, many growers use it to produce hybrids. The Californian nursery Sacred Succulents has some colored Grandiflora hybrids and they sell seed every now an then. You can also try to make a post at our Trichocereus group at https://facebook.com/groups/trichocereus   because there are some growers there who give some away every now and then.

Trichocereus grandiflorus also shows similarities to Trichocereus schickendantzii and some even consider them close relatives. It´s sometimes difficult to keep the two apart and growers or collectors mix them up all the time. The same applies to Trichocereus huascha, which differs from Trichocereus grandiflorus through its spination.

Due to the fact that there are so many misidentified Trichocereus grandiflorus, or plants that are identified as Trichocereus huascha but are actually GF, a large part of the photos that can be seen online show something else. This whole confusion is worst with small and juvenile plants. Trichocereus grandiflorus is MULTI-Ribbed and grows columnar. Its higher rib count and the strange pupping behavior in combination with shorter spines than T. huascha and its typical pupping style at the base make it possible to identify it reliably though. The pups almost look like little balls on the base of the plant while Trichocereus schickendanzii forms large clusters that can get up to 1-2 meters wide. The problem with Trichocereus grandiflorus is that the original description was written after a collection plant, which may or may not have already been a hybrid of Trichocereus huascha.

Note the differences in regards to the flower. White versions of Trichocereus grandiflorus are almost always misidentified Trichocereus schickendantzii, Trichocereus shaferi, or true hybrids involving T. huascha or T. grandiflorus that resulted in a white flower.

Trichocereus knuthianus (Echinopsis knuthiana)

Trichocereus knuthianus (Echinopsis knuthiana)

Trichocereus knuthianus is a plant that can be found in many parts of Peru. As a species, it is much more diverse than the clone that it is mostly reduced to and there are various forms that belong into the context of Trichocereus knuthianus.  In addition, there are intermediates with Trichocereus schoenii, Trichocereus tarmaensis and Trichocereus cuzcoensis.

Alternative name: Echinopsis knuthiana

Synonyms: Trichocereus knuthiana, Trichocereus knuthianus, Trichocereus cuzcoensis var. knuthianus, Cereus knuthianus, Azureocereus deflexispinus, Cereus deflexispinus, Trichocereus tarmaensis, Trichocereus peruvianus var. Tarma, Trichocereus crassiarboreus, Trichocereus schoenii, Echinopsis schoenii, Echinopsi tarmaensis (not all, but some of them clearly belong into the knuthianus context as well)

Though Trichocereus knuthianus is still considered a correct species with the name Echinopsis knuthiana, it is closely related to Trichocereus cuzcoensis and Trichocereus peruvianus. There was never any good DNA testing done to verify or question this, which is why it is on our short list of species that we´ll test for our upcoming book on the genus Trichocereus. In my opinion, it is a relative of Trichocereus cuzcoensis. We will find out how related exactly once we´ve ran some tests.

Trichocereus knuthianus was discovered and described by Curt Backeberg on the upper course of the Rio Marañon. The plant was named after Graf F.M.Knuth, who was Curt Backeberg´s co-author in the book KAKTUS ABC and a financier for some of his trips.

Rio Maranon Peru Trichocereus knuthianus Echinopsis knuthiana

Most plants that are available on the open market were originally sourced from Friedrich Ritters Seed list. Ritter´s collection number of Trichocereus knuthianus was FR567, sometimes also labeled as Trichocereus knuthianus f. pachanoi or Trichocereus knuthianus FR 677! This strain can be found in collections throughout the World though it is most common in Australia.

Ritter wrote that it´s probably synonymous with Trichocereus tarmaensis and I agree to a certain degree. In addition, he shared the opinion that Trichocereus knuthianus is actually a variety of Trichocereus cuzcoensis, which is most likely correct as well. Trichocereus cuzcoensis only grows in Cusco, but its close relatives grow all over Peru, e.g. Trichocereus tarmaensis, Trichocereus schoenii, etc.

Curt Backeberg, on the other hand did absolutely not agree with Ritter´s attempt to nullify Backeberg´s species, as it would mean that his newly described “species” would´ve become invalid. Generally speaking, Friedrich Ritter knew that plant very well .

Mature plants of Echinopsis knuthiana in habitat tend to have that tree-like rounded log-shape that you can observe on Trichocereus cuzcoensis too. Most other Trichocereus species do not form such  a rounded and tree-like stump, which is another indicator for its genetic proximity to the Cuzcoensis complex.

Trichocereus knuthianus is very widespread and grows in Central Peru and some Departments that surround it.

Trichocereus huascha (Echinopsis huascha)

Trichocereus huascha (Echinopsis huascha)

Trichocereus huascha, also known as Echinopsis huascha, is an Argentinian Trichocereus species that looks very similar to Trichocereus spachianus, Trichocereus grandiflorus, Trichocereus shaferi and Trichocereus schickendantzii. However, there are important differences to distinguish them.

Trichocereus huascha has had a long history with many name changes due to its unique position between Trichocereus, Lobivia and Echinopsis. Friedrich & Rowley renamed it to Echinopsis huascha in 1974 but their actions weren´t really embraced with love.

I have some fresh seeds of Echinopsis huascha. You can get them here:

Synonyms: Lobivia huascha, Helianthocereus huascha, Trichocereus huascha, Echinopsis huascha, Soehrensia huascha, Cereus huascha, Cereus huascha variety flaviflorus, Cereus huascha var. rubriflorus, Lobivia purpureominata, Trichocereus andalgalensis, Echinopsis andalgalensis, Lobivia andalgalensis, Trichocereus grandiflorus, Echinopsis grandiflora,

Described varieties of T.huascha:

Trichocereus huascha v. robustior or robusta

Trichocereus huascha v. pecheterianus

Trichocereus huascha v. rubriflorus 

Trichocereus huascha v. auricolor 

The list of names that Trichocereus huascha already had does not fit on one page, so I will only keep the most important ones. Many varieties of this species were actually labeled Lobivia, Cereus or even Chamaecereus and it´s very difficult to differentiate the plant from similar plants like Trichocereus schickendantzii, Trichocereus spachianus or Trichocereus grandiflorus.

Echinopsis huascha usually grows in small, clumping groups that reach up to 1,1 meters in height. It usually pups abundantly and can grow upwards like a columnar cactus or creeping. The pups can get up to 5-6 centimeters in diameter and has up to 15 ribs as a mature plant. The areoles are between 1 cm and 1,5 centimeters apart from each other. There are yellow colored and needle-like spines on each areole. Trichocereus huascha has 10-12 radial spines that are up to 2 centimeters long. The flower color is absolutely variable; also because there are SO many natural and commercial hybrids. This plant is used extensively in Trichocereus hybrid culture and many hybrids that are floating around on the market cant fully be id´d because the offspring can sometimes look very different from the parental generation. The plant flowers from the apex, through the areoles and the flower color can be yellow, red or orange. You can keep it apart from plants like Trichocereus schickendantzii by the color of the flower (Schickendantzii has white flowers) and the thinner growth of E. huascha. The flowers are 6-8 centimeters in diameter and the species is usually dayflowering! They also are sometimes self-sterile, while other forms are self-fertile. You usually need two plants to get seed, but T.huascha hybridizes so easily in nature that there are some plants that form fruit without being pollinated! There are constant arguments about its synonymy with Trichocereus andalgalensis and at the moment, I consider them synonymous. Trichocereus andalgalensis was described as a red flowering variety of T. huascha (T. huascha v.rubriflorus), but since there are also yellow flowering T. andalgalensis at the original site, this is not really a species that I consider correct.

Origin of Trichocereus huascha:

Argentina. Very widely distributed and can be found almost everywhere around Catamarca & La Rioja. The plant grows at 900-2000 meters altitude.

Trichocereus skottsbergii / Echinopsis skottsbergii (T. chiloensis)

Trichocereus skottsbergii / Echinopsis skottsbergii (T. chiloensis)

Trichocereus skottsbergii Backeberg, also called Echinopsis skottsbergii, is a columnar cactus that is closely related to Trichocereus chiloensis / Echinopsis chiloensis. Under current taxonomy it is placed as a subspecies below Trichocereus chiloensis with Echinopsis skottsbergii as currently accepted name.

The species was described by Curt Backeberg and named after Mr. Carl Johan Fredrik Skottsberg. Friedrich Ritter noted that it grows together with Trichocereus chiloensis without forming zones of hybridization. The easiest way to differentiate Tr. skottsbergii from Trichocereus chiloensis is by comparing the number of ribs. Echinopsis skottsbergii has 16-21 ribs, while Trichocereus chiloensis only has 16-18 ribs.

Curt Backeberg gives the form T. skottsbergii v. breviatus as a valid variety, but it was probably just a regional form of the same species. In the past, there were many unnecessary descriptions made that would not stand today. In my personal opinion, all the Chilean Trichocereus species are so closely related that it might not be a bad idea to consider them as one, very big and variable species. The same treatment works well with the whole group of species around T. peruvianus.

In Chile, the variability of the genus Trichocereus is just as big as the variability of Trichocereus species in Peru or Bolivia. E. skottsbergii is extremely close to Trichocereus litoralis, also known as Trichocereus chiloensis ssp. litoralis as well. It is very difficult to distinguish them and descriptions are absolutely necessary.

Trichocereus smrzianus / Echinopsis smrziana

Trichocereus smrzianus / Echinopsis smrziana

Backeberg described Trichocereus smrzianus / Echinopsis smrziana in his KAKTUS ABC, a book that did not get a very wide release. Besides the description is highly controversial because it basically re-describes various forms of Echinopsis schickendantzii / Trichocereus schickendantzii and Trichocereus walteri that are barely on the level of a regional form.

Synonyms: Trichocereus smrzianus, Soehrensia smrziana, Soehrensia smrzianus, Echinopsis smrzianus, Echinopsis smrziana, Trichocereus schickendantzii, Echinopsis schickendantzii, Trichocereus walteri, Echinopsis walteri, etc.

Origin of Trichocereus smrzianus:

Argentina, Salta

Description of Echinopsis smrziana:

This species grows alone or in groups of larger clusters. It has a large, round body and reaches a maximum diameter of 2 meters and can get up to 60-70 centimeters tall. The plant is extremely variable and can grow like a clustering cactus like Trichocereus schickendantzii or in a columnar way, very similar to Trichocereus spachianus. It has 10-15 ribs and only grows at one location, which was also described as the type locality. T.smrzianus is extremely rare, though it is sometimes available on the commercial and sometimes shows up in cactus collections. The fact that the plant has so many ribs, makes it distinguishable from plants like Trichocereus candicans or Trichocereus spachianus. Young plants can look almost identical though, which is why identification of this species should not be done on juvenile plants. The bigger the plants, the broader the ribs are, what gives it a very typical Soehrensia look and it looks much closer to Soehrensia than to Trichocereus.

Spines of T.smrzianus:

The very thin spines are usually yellow to white. Plants have 8-15 spines on one areole, but Trichocereus smrzianus is extremely variable, what makes it so hard to ID. If you encounter the plants in the field it should be fairly easy to identify because it only grows on one location in Chachipampa, Argentina. It has 1-4 middle spines that are up to 3 centimeters long.

Flowers of E.smrziana:

Trichocereus smrzianus has white flowers, almost identical to the ones on T. schickendantzii. Overall it is a form of the latter, which means it is very hard to distinguish it from it. The plant flowers from the upper part of the body, what you can see on the featured image very well. The flowers get between 10-20 centimeters long and look very similar to the ones on Trichocereus tarijensis.

Fruit:

Trichocereus smrzianus has a round, green fruit that is between 2-5 centimeters in diameter and tastes very nicely. The name is a really bad example of how a name should not be. Not sure how it sounds in your language but in mine it sounds like having a seizure while biting your tongue off.
The taxonomic status of this group of plants was very inconsistent and due to the fact that there is a relationship to the genus Soehrensia, taxonomists have moved them back and forth from Trichocereus to, Soehrensia and Echinopsis now. After the merger with Echinopsis, taxonomy went full circle and re-declared Soehrensia as an accepted genus and it seems like it might stay like that. However, the plant is definitely close to Trichocereus schickendantzii and it´s definitely possible that Trichocereus smrzianus is just a natural hybrid between Trichocereus schickendantzii and a different species like Trichocereus tarijensis, or a regional form of the Trichocereus schickendantzii group.

Trichocereus deserticolus (Echinopsis deserticola)

Trichocereus deserticolus (Echinopsis deserticola)

Trichocereus deserticolus, also known as Echinopsis deserticola, is a columnar cactus from Chile. This species also includes Trichocereus fulvilanus / Echinopsis fulvilana as a subspecies of Echinopsis deserticola now.

Trichocereus deserticolus / Echinopsis deserticola Patrick Noll

Trichocereus deserticolus is a plant with a complicated and close relationship to Trichocereus fulvilanus, Trichocereus coquimbanus and Trichocereus chalaensis. They get very close to each other sometimes, for example the population between Paposo and El Cobre. Trichocereus fulvilanus grows from Caldera in the north to El Cobre, while Trichocereus deserticola grows from Paposo down in the south to Tocopilla in the north.   There are taxonomists or authors that regarded Trichocereus fulvilanus as being unrelated to Trichocereus deserticolus / Echinopsis deserticola, but I do not really share this opinion. Yes, there certainly are differences between Trichocereus deserticolus and Trichocereus fulvilanus, but a blind man could see that both are as closely related as it can get.

Synonyms of E.deserticola:

Echinopsis deserticola, Trichocereus deserticola, Cereus deserticola, Cereus fulvilanus, Echinopsis fulvilanus, Echinopsis fulvilana,Trichocereus deserticolus, Echinopsis deserticolus

Origin of T.deserticolus:

Chile. The type location is Antofagasta. It also grows around Atacama, El cobre, Paposo, Tocopilla, etc. Trichocereus deserticolus grows in a moister climate than Trichocereus fulvilanus, which grows around the coastlines and that prefers a drier climate. Because of that, Trichocereus deserticolus can rather be found in the higher areas around Paposo, where it is extremely common.

Description of Tr. deserticolus: 

Trichocereus deserticolus is a branched plant that does not get as big as other Trichocereus species. It´s usually somewhere between 1-2 meters tall, but most of them are around 1 meter.

Ribs:

9-13, with very strong furrows. This plant is somewhat similar to Trichocereus chalaensis, which grows creeping.

The areoles are 1-2 centimeter apart of each other. Trichocereus deserticola usually has 2-3 middle thorns and 18-24 radial thorns. Which are very thin and have a dark brown/reddish color. The epidermis of the skin shows a very weak, pale green color.

Flowers: The flowers are white and a little bit smaller than the ones on other Trichocereus species. The size of the flowers is between 5 and 12 centimeters. They have brown/black hairs and the fruits are round and can be eaten.

In a wider sense, this plant is most likely related to Trichocereus chiloensis as well. However, the exact genetic situation has to be revealed by DNA testing. 

Cultivation:

Trichocereus deserticolus should be treated just like every other Trichocereus from Chile. It only needs watering during the hot season and requires a soil that dries out very fast. I usually use purely mineral soil mixes and as Chilean Trichocereus species, Trichocereus deserticolus aka Echinopsis deserticola likes it a lot

Buy T.deserticolus:

There are almost no seeds of Trichocereus deserticola available. Sometimes you can get small cuttings on sites like eBay. I sometimes have seeds of this species available and I can recommend that you join our Trichocereus group or Newsletter to stay in touch.

Winter protection:

Trichocereus deserticolus should not be kept at temperatures below -5° Celsius and the plants have to be completely dry if you want to overwinter them at a cold climate. A perfect overwintering temperature is around 10° celsius, which is something around 50° Fahrenheit. The plants should be kept at a bright and well ventilated area.

Trichocereus cuzcoensis – Echinopsis cuzcoensis

Trichocereus cuzcoensis – Echinopsis cuzcoensis

Trichocereus cuzcoensis is a Trichocereus species from Cusco in Peru. It is described as from Cusco and in sense  of the description plants only count as being part of this species if they are from Cusco, but close relatives of Trichocereus cuzcoensis also occur in many other parts of Peru, e.g. Trichocereus knuthianus, Trichocereus schoenii, Trichocereus tarmaensis, etc.

Trichocereus cuzcoensis is currently still called Echinopsis cuzcoensis, but many good authors have abandoned this sinking ship and went back to use the Trichocereus names. Trichocereus cuzcoensis, also known as Echinopsis cuzcoensis, is an accepted species, despite it´s obvious similarity to Trichocereus peruvianus. There are countless intermediates between Trichocereus peruvianus and Trichocereus cuzcoensis (especially where both grow together) and there are many regional forms that show traits of both species.  As an example, there are Peruvianoid forms of Trichocereus cuzcoensis and there are specimens of Trichocereus peruvianus that show some traits of Trichocereus cuzcoensis. Personally, I think that Trichocereus cuzcoensis and Trichocereus peruvianus are so similar that they are at least subspecies or varieties of the same species. We´ve already seen lots of different regional forms of Trichocereus cuzcoensis. Everywhere T.cuzcoensis grows in direct neighborhood of Trichocereus peruvianus, they hybridize with each other and form transitional forms. The whole group around Trichocereus peruvianus is extremely variable and that also includes Trichocereus cuzcoensis as well. Please note that Trichocereus cuzcoensis is MORE than just Karel Knize´s KK242, which has become THE textbook definition of a cuzco. The hate around KK242 is responsible for giving the species a bad rep and that´s absolutely not justified as far as we are concerned. It´s a beautiful and unique species and large mother plants are usually stunning.

Because there are countless forms of Trichocereus cuzcoensis or its close relatives, we started collecting as many photos as we can to put them here together. 

Description of T. cuzcoensis:

Trichocereus Cuzcoensis is a columnar cactus that grows columnar and is pupping from the base. It can get more than five meters tall, though most collection plants that are grown in pots do not exceed 2 meters. However, in countries like Australia, there are many huge plants of Trichocereus cuzcoensis to be found. New growth has a bright green color. It can get between 7 -9 rounded Ribs and the areoles are approximately 1-2 centimeters apart from each other. Trichocereus cuzcoensis has many, very strong spines. The number of spines is very variable but in most cases, I observed between 8-12 spines. The spines usually have a rounded, knobby base. New spine growth is yellow or dark brown while old spine growth is usually dark gray to white with slight black undertones or black spine tips. The spines usually are between 5-10 centimeters long. If you have a suspected E.cuzcoensis with a low rib count, it is likely not a Cuzco but a close relative such as the plants from San Marcos, T. schoenii, T. santaensis, etc.

Trichocereus cuzcoensis is a night-flowering species but the flowers usually stay fresh until the morning of the next day. It is self-sterile and you need another specimen as pollen donor in order to produce seed.

Flower:

The flower color is white and the flower is usually very large. It measures up to 16 centimeters, the tube is green and 7-8 centimeters long. Petals are approximately 5 centimeters long and there are hairs covering the flower.

Type locality:

Peru, Cuzco. Cuzcoensis relatives from other areas do not count as T.cuzcoensis is the sense of the description.

Synonyms, commercial names & Varieties:

Trichocereus knuthianus, Trichocereus crassiarboreus, Cereus cuzcoensis, KK242, KK340, KK1911 Knuthianus, Trichocereus tarmaensis. Please note that some of these are close relatives that we count in the winder context of this species.

Cultivation:

Trichocereus Cuzcoensis is grown just like other Trichocereus species. It´s a very tough and frost hardy species and is able to cope with temperatures down to -9° celsius/15.8° Fahrenheit for short periods of time. The minimum average temperature is 10° celsius/50° fahrenheit. That temperature is also the minimum temperature that it needs to stay healthy during the winter.

Winter protection:

Trichocereus cuzcoensis can be overwintered in a bright and well ventilated place. The temperature should be around 9-10° Celsius and the plants need to be completely dry. In european countries, the growers stop giving water and fertilizer in late summer (September or October) and take em in until early May or April. Keeping the plants dry and cold over winter also helps to increase flower production. Plants that are kept in a warm room over the winter lose their ability to flower. Besides, plants or seedlings need to be watered on a regular basis as soon as you have them in a heated room. If you want to overwinter a Trichocereus in a warm room (20°-30° Celsius), you have to water it on a regular basis. You can only overwinter a plant “dry” if the temperatures are low.

Growing Trichocereus cuzcoensis from seed: Trichocereus cuzcoensis is very easy from seed, because it is relatively resistant to most pests. One of the biggest challenges is to get good quality seed because most cuzcoensis seed on the market is pretty old and some do not even germinate. I am constantly looking for interesting new types of Trichocereus cuzcoensis, because they are amazing plants. Take a look at the pics from the Sacred Succulents Field Trips that are labeled “Cuzcoensis” and you will most likely agree. Germination temperature for Trichocereus cuzcoensis is between 26° and 30° celsius. It only needs very little water to induce germinations and if you have quality seed, they will germinate within 2-6 weeks. If nothing shows up by the 6th week, you will probably not get germinations at all. In this case, remove the lid, let the soil dry out and start with the germination process again. Those cycles mimic the way this actually happens in nature and sometimes, you will be able to re-activate dead seed. You can also add GA-3, which is Gibberelic Acid or use a strong HPS or LED lamp to wake the seeds up, because ultraviolet light increases germination rates. In general, Trichocereus seeds need light to germinate, so do not cover them with soil.

Trichocereus cuzcoensis Seed Sources: I have some great seeds in my shop right now. The first one comes from Huancavelica in Peru and the other one is somewhere between Trichocereus peruvianus and Trichocereus cuzcoensis.

Trichocereus cuzcoensis KK242 Master Evan EchinopsisThis looks like a very typical Trichocereus cuzcoensis KK242. This strain was originally brought into cultivation by Karel Knize. He also sold various types of similar plants labeled as Trichocereus cuzcoensis, Trichocereus macrogonus or Trichocereus peruvianus. The label KK242 does not refer to a particular plant but the area where the seeds/cuttings were collected at. Because of that, there are many plants labeled KK242 which are NOT a Trichocereus cuzcoensis. The type just looks so unique and remarkable that it stuck and most plants that look like this are usually identified as KK242. Which is not really correct because that´s just one of the many types that grow within the KK242 range. However, most of the KK242 are in fact Trichocereus cuzcoensis. Pic: Master Evan

Trichocereus chiloensis (Echinopsis chiloensis) T.chilensis

Trichocereus chiloensis (Echinopsis chiloensis) T.chilensis

Trichocereus chiloensis, also known as Trichocereus chilensis or Echinopsis chiloensis, is a columnar cactus from Chile. It is closely related to Trichocereus terscheckii and something like the Chilean version of the large Andean Trichocereus species.

Current name:

Echinopsis chiloensis H.Friedrich & G.D.

Synonyms of T. chiloensis:

T. chilensis, T. chiloensis, Echinopsis chilensis, E. chiloensis, Cactus chiloensis, cereus chiloensis, Trichocereus skottsbergii, Trichocereus nigripilus, Echinopsis skottsbergii, Echinopsis nigripilus, Trichocereus spinibarbis. Trichocereus litoralis, Echinopsis litoralis, Trichocereus bolligerianus, Echinopsis bolligerianus

It´s debatable whether or not Trichocereus litoralis and Trichocereus coquimbanus are synonymous with Trichocereus chiloensis, but there is a clear connection and intermediates exist. 

Some people consider Eulychnia eburnea to be synonymous with Tr. chiloensis / E. chiloensis, but I disagree vehemently. The plants look kinda similar, but the flowers of them are very different and clearly belong to the genus Eulychnia.

This Trichocereus species is the predominant Trichocereus in Chile. The Name “chiloensis” is the taxonomically correct one, but there´s a very high chance this was typo as the name was supposed to mean”Chilean Trichocereus” and not “Trichocereus from Chiloe”. T. chilensis doesn not grow anywhere near the island of Chiloe. This makes the confusion around the name even more ridiculous. I understand that Taxonomy has to prefer the earliest name recorded, but in this case, the name Trichocereus chilensis should be ignored because it is the taxonomic equivalent of a typo.

Trichocereus chilensis grows from the Provence Talca in the south of Chile down to the Elqui Valley in the Provence Coquimbo in the north. There are various varieties and the maximum size of the plants varies greatly. Trichocereus chiloensis is one of the most typical cacti in Chile, grows like a tree and can get up to 6-7 meters tall. It grows as strong columns that reach a maximum diameter of 15 centimeters. The areoles are white/beige and up to 2 centimeters long. It has 10-12 radial spines that are up to 2 centimeters large and 2-4 middle spines. The middle spines are usually between 5-10 centimeters long-

Flower: The flower of Trichocereus chilensis is a little smaller than the ones on other Trichocereus species. It is between 8-14 centimeters long. The tube has very little hair on it and is 4-6 centimeters long, white petals (up to 5 centimeters long). Trichocereus chiloensis is a diurnal species, but the flowers tend to stay open for a very long time, sometimes even up late into the night so you might get the idea it is actually night flowering. There are many varieties or intermediates of Trichocereus chilensis, which grow all around the habitats and in the area where different types grow in the neighborhood of each other.

Cultivation of E. chiloensis:

Trichocereus chiloensis is a very tough cactus, just like many other cacti from Bolivian or Chilean deserts . They can take extreme heat and are very easy to grow. But they don’t like too much water, so you should never give too much water at once. They should only be watered in summer and require dry soil medium during the winter. Besides, they need a temperature change during the water in order to produce flowers. That means that you should overwinter Trichocereus chiloensis in a bright and well-ventilated room between October and April until there are no more night frosts. Trichocereus chiloensis is able to tolerate slight night frosts but the temperatures should not drop below -9° Celsius or you might lose the cactus. Apart from that, Trichocereus chiloensis is really easy and can thrive on very poor soil medium. I can recommend purely mineral soil mixes for them because they tend to rot when there is too much humus in the soil. A cactus that is kept in a mineral substrate can stay wet for much longer without any damage to the roots that one that is grown in a highly humus substrate.

Growing Trichocereus chiloensis from Seed: Trichocereus chiloensis is similarly easy from seed as any other Trichocereus. The seeds stay long for 5-10 years, though it´s best to use seeds that are not older than one year. The seeds need light to germinate and you usually sprinkle them on top of the soil and put the pot/sowing container in a room with a temperature between 25-30° Celsius for 2-6 weeks. If you still have no seedlings after 2-6 weeks, chances are that the seeds are not viable. There are not many suppliers for seed of Trichocereus chiloensis. 

Right now I have a terrific strain of Trichocereus chilensis ssp. litoralis in my shop. Check it out here.

Trichocereus deserticolus / Echinopsis deserticola

Trichocereus glaucus – Echinopsis glauca

Trichocereus glaucus – Echinopsis glauca

Trichocereus glaucus, also known as Echinopsis glauca, is a Peruvian Trichocereus species described by Friedrich Ritter.

Trichocereus glaucus Echinopsis glauca Friedrich Ritter original photo

Friedrich Ritter original photo

Trichocereus glaucus – Foto: Friedrich Ritter

Origin of Trichocereus glaucus:

Peru ( South Peru ), Arequipa (Rio Tambo), Chile. In Chile, this plant is closely related to Trichocereus fulvilanus and Trichocereus deserticolus.

Description of Trichocereus glaucus / Echinopsis glauca:

Trichocereus glaucus Echinopsis glauca Auxin photo

Trichocereus glaucus can get between 1,5-2 meters tall and is a prostrate/creeping species that you often find hanging down slopes and cliffs. This trait is very distinct in the variety Trichocereus glaucus var. pendens. The color of the skin is very glaucous and small specimens look absolutely like the type of plants that are labeled Trichocereus macrogonus / Echinopsis macrogona today.  Spiny, dark blue versions from the complex around T. peruvianus. However, macrogonus grows columnar while this species tends to bend over with age. New growth is very glaucous.

Areoles of Echinopsis glauca:

The areoles are dark brown to gray in color and approximately 2,5 centimeters apart of each other. Similar to other plants related to Trichocereus peruvianus, the plant has a diameter of up to 10 centimeters and the areoles are gray felted. The spines look a bit like the ones on Trichocereus cuzcoensis and old growth has a typical satin white glow that is common on this species. Trichocereus glaucus has 6-9 ribs, 3-6 middle spines and 8-11 radial spines. The middle spines are 5-10 centimeters and the radial spines 1-2 centimeters long.  New spine growth is black to brown and turns gray with age.

Flowers of T. glaucus:

White, just like almost every other Trichocereus from this complex. The diameter is very variable and usually is between 15-22 centimeters. Trichocereus glaucus is a night-flowering species with green, round fruits. However, the hairy flowers usually stay open until the next morning.

Fruit of E. glauca:

Round, green, and 3 centimeters thick.

Type locality: Lower part of the Rio Tambo in the department Arequipa.

Trichocereus glaucus is very similar to Trichocereus chalaensis and grows in a similar way. We think that Trichocereus chalaensis might be synonymous with Ritter´s Trichocereus glaucus. Ritter´s field number of Trichocereus glaucus was FR270. We distributed seeds of Trichocereus glaucus various times in the past and all ended up amazingly beautiful. It´s a very nice species.

Buy Trichocereus glaucus seeds:

Trichocereus glaucus aka Echinopsis glauca is extremely rare and most plants on the market will probably come labeled as “Trichocereus peruvianus” or “Trichocereus macrogonus”. It is common occurence for some Peruvian cactus collectors to label all glaucous Trichocereus species with this name. This is obviously wrong and causes chaos. We sometimes have plants of this species in our Trichocereus Facebook group, which can be found here: https://facebook.com/groups/trichocereus

Cultivation of Echinopsis glauca:

Trichocereus glaucus is a very resilient grower and likes to be watered well in summer. In winter, they should be kept as dry as possible at around 10° Celsius. Seed germinates very well and the plant is usually very tough. That´s also caused by its drought tolerance, which is very typical for these kinds of plants. The species will probably tolerate temperatures between -5° to -7° Celsius over very short time, but I would not stress it and this also depends on many other factors, like general health and dryness. I would recommend keeping at no lower than 10° Celsius in winter.

Varieties of E. glauca: Trichocereus glaucus var. pendens. This variety does only grow hanging down cliffs and small hills. This variety only grows at one location in Chile and is extremely rare. This local population is in the south of Arica, Camarca in Chile. Backeberg suggested that this would be his Trichocereus uyumpaensis, but Friedrich Ritter vehemently disagreed with that. More information is necessary about this topic.

Translation of Ritter´s description (loosely)

This species forms shrubs the size of 1 – 2 meters and often several meters in diameter, sprouting mainly from shoots that lay sideways on the ground. This plant rarely pups from the top or upper parts. The shoots are 5 – 8 inches thick, erect, later lying in the lower parts, the new shoot blue-green, later gray-green.

Ribs: 7-9, very broad, obtuse, 7.5 to 13 mm high, 15-25 mm wide, notched, with transverse furrows that do not reach down to the separating grooves of the ribs,
areoles: grey felted, 1/2-3/4 inches in diameter, 1 to 2 inches free removal, let down by the humps in the notches
Spines: In the new shoot black to brown, becoming gray, straight, rigid
Marginal spines: 7-10, directed laterally, the lower and lateral 8 to 15 mm long, coarse needle-shaped, somewhat flattened, the upper the upper stronger and not sharply separated from the Central spines.
Central spines: 3-6, very spread apart, subulate in the middle, but usually closer to the top edge and almost in the position of an edge of spine, below 1.5 mm thick
Flower: Not far from the apex, 13 to 19 centimeters long, fragrant, opening in the evening, the morning still open,
Ovary: Green with fleshy green, narrowly triangular, 2-5 mm long, pointed scales and large scales raised bases. The flowers are covered with brown/black hairs.
Partition against the nectar chamber 3-4 mm thick, tube-shaped, 13 to 23 mm long, to the stylus 1to 2 mm wide, brownish, almost openly, with nectar

Tubes:

In addition funnel shaped, 40-65 mm long, the top 2 to 3 cm wide, pale green interior, exterior gray-green, with triangular points, 7.5 to 10 mm long, dark green scales and tufts of hair as on the ovary.
Stamens: white, greenish below, insertions missing on the top 2 to 3 centimeters of the tube to a ring on the hem, pouch pale brown, approximately at half height petals standing

Trichocereus riomizquensis RITTER (Echinopsis)

Trichocereus riomizquensis RITTER (Echinopsis)

Trichocereus riomizquensis is a Bolivian Trichocereus species that is closely related to Trichocereus bridgesii. I count it as a close relative and potential regional form of Trichocereus bridgesii, which is only endemic to one site in Bolivia near the Rio Mizque.
The species was discovered and described by the German cactus field botanist Friedrich Ritter, who gave Chuyllas as the type locality and described it growing on steep slopes in the province Campero.

His Field Number was FR 856. Friedrich Ritter was one of the leading Cactus experts of his time and successfully ran a seed shop, in which he sold this species as seed to people all over the world. Trichocereus riomizquensis was also visited during the Sacred Succulents Fieldtrips and they found a couple of different types growing around that area.

In Ritter´s book, he published a photo of this species. Unfortunately this photo is not very good and it is one of the species that are rare in cultivation. Almost all labels on plants grown from Ritter´s seeds are lost, but the plant is definitely available. On the market, it sometimes shows up labeled as Trichocereus bridgesii, or probably also labeled as Trichocereus PC. Please note that there is a wide variety of plants from this site and the range is very big, ranging from spiny to completely spineless plants.

Ben Kamm published some photos of a Herbarium specimen that was very close to Trichocereus bridgesii as well.

Where to buy seeds and plants of Trichocereus riomizquensis?:

Though Trichocereus riomizquensis is common in cactus collection in the USA, it is usually mislabeled. Sacred Succulents were giving away seeds after their Field Trips and some plants might have gotten into the hands of collectors. They are also selling live plants grown from their collected seeds sometimes.

Description of Trichocereus riomizquensis:

This is partial description of Friedrich Ritter´s original description, including remarks on how to keep it apart from T. scopulicola.

Trichocereus riomizquensis is 6-8 centimeters thick (while Trichocereus scopulicola is 8-10 centimeters thick), it has 5-6 ribs, (T. scopulicola: 4-6), its flanks are 2 centimeters wide (Scopulicola 3-4 cm wide flanks), the flanks are less rounded than the ones on Tr. scopulicola. It has rounded areoles (while the ones on T. scopulicola are usually oval). The areoles have a very visible fluff with a diameter of 2-3 mm. The 1-5 spines are honey-colored and between 1-3 mm long. Sometimes they are even missing.
The flower of Trichocereus riomizquensis is 20 centimeters long (while the flowers of T. scopulicola are 16-20) and covered with dark brown/white wool with large scales. The fruit looks knobby.

Type locality: Chuyllas near the Rio Mizque, on very steep rock walls in the province Campero, Bolivia. Discovered from Ritter in 1958 – FR 856.

BK10512.1 Trichocereus riomizquensis, Totora, Cochabamba, Bolivia

Trichocereus riomizquensis is one of the most interesting species from the Sacred Succulents Field Trips because of its incredible range. Some plants look like the Trichocereus bridgesii-type plants with long spines from the Field Trips and some other ones look like the short spine versions that Friedrich Ritter´s description was about.

If you take a close look at the whole appearance of this plant, you can see that it has a similar areole shape to the areoles on the well known Trichocereus PC clone, also known as predominant cultivar or predominate cultivar.  The flower and the overall appearance are so similar that everything else would be extremely surprising. Despite the fact that there are some very spiny plants at this site, there are some other which get extremely close to Ritter´s original photo. Though this will probably never be proven, there´s definitely reasonable doubt that this PC clone is actually a Trichocereus pachanoi.

There is a lot variation within the populations the original site near the Rio Mizque. This population is one of the most interesting Trichocereus populations out there and DNA testing should absolutely be made to look into its relationship to Trichocereus bridgesii.

Where to buy seeds or cuttings of Trichocereus riomizquensis:

Well, Ben and Sacred Succulents would be my starting point if I were in the USA. They don´t ship plants internationally, but if you have the luck to be in the country you might be able to get some cuttings. Apart from this, I do not know any sources for this species. Most of Ritter´s old plants have lost their labels meanwhile, which makes getting one even harden. I am sure that some of them show up on online market places labeled as Trichocereus bridgesii every now and then.

Trichocereus santaensis / Echinopsis santaensis descriptions

Trichocereus santaensis is columnar cactus and species described by Curt Backeberg and Werner Rauh. It is endemic to the Santa Valley in Peru. There are many different forms that belong into the larger context of T. santaensis, e.g. Trichocereus sp. Chavin de Huantar also known as El Lanzon, Trichocereus huanucoensis, Trichocereus pallarensis and many others.

Trichocereus santaensis Chavin de Huantar Echinopsis Chavin Herbalists

Echinopsis santaensis Trichocereus santaensis Rio Santa Peru Valley

Origin of Trichocereus santaensis

Northern Peru, the valley around the Rio Santa, Puente, Bedoya, Huayanca

Can be kept apart from Trichocereus cuzcoensis by the absence of swollen spine bases. It also has a more frosted blue skin color, has fewer spines and shorter middle spines. Unlike Trichocereus peruvianus, it grows always columnar and does not grow prostrate.

trichocereus santaensis Huntington Botanical Garden Echinopsis santaensis HBGTrichocereus Santaensis – Huntington Botanical Garden – by Richard Hipp!

Description of Trichocereus santaensis Rauh & backb g -. Descr. Cact. Nov. 20, 1956

Trichocereus santaensis can get up to five meters high and branches from the bottom. The stems are blue-green to a glaucous green. It has 7-9 ribs that are similarly broad than the ones on Trichocereus knuthianus aka Echinopsis knuthiana. There is a distinct furrow above the areoles. This distinct V-Notch is very strong in young pups. The areoles have a diameter of approximately 1 centimeter and Trichocereus santaensis has between 1-3 radial spines. Spines medium long to short. In addition, Trichocereus santaensis has one very long middle spine, which is up to 5 centimeters long.

Flower: The flower is white and gets up to 22 centimeters in length. It has a similar flower than other San Pedro types, which is another indicator that Trichocereus santaensis is just a regional form of another species, e.g. T. pachanoi or T. peruvianus.

Origin/Habitat: Rio Santa, Puente, Huayacana, Bedoya.

Trichocereus santaensis is very similar to Trichocereus cuzcoensis and is constantly confused with it. However, it does NOT have rounded, knobby spine basesBesides, the spination is less strong and grows always columnar instead of creeping. Today, the species would probably not be considered to be correct and extensive DNA testing is necessary to look into the limits of this species and where other species begin.

Please note that T. santaensis is very variable due to the high number of regional forms. Some of which have red spines, some with yellow spines and some where the spines are completely absent.

trichocereus santaensis Echinopsis santaensis Rio Santa

 

In the Chapter of Trichocereus peruvianus, Backeberg wrote about its growth type:

I even found the Type initially growing erect, then lying or hanging . But near Matucana (Sic!), there also are upright growing varities of Trichocereus santaensis, which probably weren´t recognized as a seperate species.
The identification of these species with Tr. macrogonus (KKDE., 20, 1941) i cannot agree with. 
However, I definitely think that some of the more spiny forms of T. santaensis could´ve been the lost T. macrogonus. Some of them are extremely spiny.

Trichocereus scopulicola / Echinopsis scopulicola

Trichocereus scopulicola / Echinopsis scopulicola

Trichocereus scopulicola is a Bolivian Trichocereus species.

Trichocereus scopulicola FR991 Rod

Trichocereus scopulicola FR991 (Rodni Kisar)

Synonyms of Trichocereus scopulicola:

Echinopsis scopulicola, Trichocereus cv. Super Pedro, Trichocereus scopulicolus, Trichocereus scopulicola NMCR, Trichocereus cordobensis, Trichocereus crassicostatus, Scop,

Origin:

Trichocereus scopulicola was discovered by Friedrich Ritter during one of his expeditions to Bolivia in 1959. The location of the type is Tarija, Bolivia. More precisely, Ritter gave Tapecua as the location and assigned the collection number FR991 and sold seed of his discovery through his legendary Winter Seed lists. Because of that, he helped spreading the plant all over the world, despite the fact that Trichocereus sScopulicola is really rare in nature. There are very few collections of this plant in nature and I am always interested in obtaining seed from new scopulicola types. The plant grows in Tarija in the province O Connor. And no, this has nothing to do with Sarah Connor from the movie TERMINATOR. Trichocereus scopulicola grows in the cactus forests around the Department Tarija at around 1000-1500 meters.

Description of Trichocereus scopulicola:

Trichocereus scopulicola grows columnar like a tree and pups from the base. But it´s actually rare for this plant to produce numerous shoots and most plants don´t have any side shoots. Trichocereus scopulicola can get up to 4 meters tall though most specimens are smaller. The columns are between 5-10 centimeters in diameter and have a nice, dark green epidermis.

Ribs:

Trichocereus scopulicola can have 4-6 ribs though most specimens have five. The areoles are furrowed. The areoles are sunk in and have very little white fluff/wool on top of them. The areoles are rounded or oval and are between 1-4 mm long and 1-2 mm broad, which is very small for a Trichocereus. The distance between the areoles is between 15 and 30 mm. Areoles that form flowers have 4-5 mm diameter. Large, adult plants often lack the spines, while very young seedlings look remarkably similar to a Trichocereus pachanoi and can only be differentiated by the weird rib shape of Trichocereus scopulicola. Adult plants have (if they have any) 3-6 spines that are very small and up to 1.5 mm long. Seedlings have 6-7 ribs, areoles up to 2 mm in diameter and 3-5 mm away from each other, 7-14 needle-like spines (2-3mm long), of which two are central spines.

Flower of Echinopsis scopulicola:

Trichocereus scopulicola flowers from the apex but there are plants where the flowers come out from lower points on the plant. The flower is white and between 15-22 centimeters long. Trichocereus scopulicola is a night-flowering species but the flowers stay open until the late morning.

Fruit:

The fruit of Trichocereus scopulicola is green and can get up to 6 centimeters thick.

Friedrich Ritter considered this species to be very close to Trichocereus bridgesii, which is one of the plants that grow in the neighborhood of Trichocereus scopulicola. And it´s very likely that Tr. scopulicola is some kind of natural hybrid involving Trichocereus bridgesii or Trichocereus pachanoi.

In addition, Ritter wrote that Trichocereus riomizquensis is related to it, but not as closely related as Trichocereus crassicostatus is. These days, Trichocereus crassicostatus is generally seen as a synonym of Trichocereus scopulicola or Tr. pachanoi. So far, I´ve not been able to track a specimen down but they are certainly out there. If you grow one, let me know.

Cultivation of Trichocereus scopulicola:

Trichocereus scopulicola is similarly tough as Trichocereus bridgesii. The reason is simple; both come from Bolivia and are used to the same conditions. Bolivian Trichocereus species are very drought resistant, but can also deal with strong rainfalls in summer pretty flawlessly. However, they should not be watered when it´s cold and they prefer a purely mineral soil mix because that dries up a lot faster. During the hot summer season, they can be watered every few days when the soil has dried up again. Don´t water them when it´s cold or rainy because that can cause rot.

Winter protection and Minimum Temperature:

Scops are relatively hardy and can short night frosts of down to -5° Celsius and maybe even lower than that, but I would not test it out because low temps weaken the plants. The minimum average temperature should be around 10° Celsius and they should be completely dry over winter if you take the plants inside. If the get wet over a prolonged period of time, it can cause root rot or other infections.

Seed & live cuttings:

I get seeds every now and then and I know a couple of growers who actively breed with Scops. There sometimes are some available at SAB and the SAB forum. Besides, Misplant makes a couple Scop Crosses a year. This year, he made a pretty cool cross between a Scop and a colored Grandiflorus, which I can wholeheartedly recommend you because it might produce Scop seedlings with a colored flower.

Trichocereus scopulicola can be used as a grafting stock. It is a great stock that accepts graftings very easily.

Trichocereus camarguensis / Echinopsis camarguensis

Trichocereus camarguensis / Echinopsis camarguensis

Trichocereus camarguensis, also known as Echinopsis camarguensis, is a Bolivian cactus from Camargo.

Synonyms of Trichocereus camarguensis:

Echinopsis camarguensis, Trichocereus caulescens, Echinopsis caulenscens

Trichocereus camarguensis is a thin Cactus that resembles Trichocereus strigonus, huascha and some forms  of T. spachianus. It has golden Spines. Live cuttings and seeds of Trichocereus camarguensis were distributed by various sources, including Karel Knize under the collection Number KK1414. There also are many hybrids available. Trichocereus cajasensis is closely related and is considered to be a separate species by some authors. DNA testing is necessary to look into this.

Description of Trichocereus camarguensis: 

Thin columnar cactus that can get up to 50-60 centimeters tall. It grows prostrate and usually leans forward because of its tendency to creep. The epidermis is bright to pale green with many golden spines. 13-15 ribs and areoles are around 1 centimeter apart of each other. This cactus can resemble Trichocereus huascha and Trichocereus strigosus, but does not reach its large height!

Spines: 

12-15 radial spines and 1-3 middle spines that are up to 5 centimeters long, The spines are bright yellow and like very thin, fine needles.

Flower:  

White. Up to 22 centimeters long, tube with dark gray hairs, sepals are pink/purple/green and white petals (up to 10 centimeters)

Fruit of Echinopsis camarguensis:

Round fruit, up to 3 centimeters in diameter

Origin:

Bolivia, near Camargo, 2750 meters. Chuqisaca, Tarija, Potosi

Trichocereus camarguensis is a night-flowering species. It also is self-sterile, what means you need pollen from a second plant to get seeds.

Cultivation of T. camarguensis:

Trichocereus camarguensis is USDA 10-12. It originally comes from Bolivia, where there is very little water and should not be overwatered. They are much more likely to rot than a Trichocereus pachanoi or Trichocereus peruvianus. So keep them more on the dry side and don’t water when it’s cold or rainy because that attracts mold and other infections. They like a mineral substrate and can deal with quite a lot of sun. The minimum average temperature should not go below 10° Celsius and that´s actually the temperature that you should overwinter them. Only water them between May and October if you have to bring them inside to overwinter. If you don´t have the luck to live in a country where you can grow them outside,then better not try it because they will most likely not make it through the winter! Just make sure to provide them with a winter protection that keeps em from getting wet all the time. They should take short, nightly frosts, but the absolute minimum is -9° Celsius/15.8 Fahrenheit. Frost resistance also depends on many other factors, like general health, soil composition and humidity.

Growing Trichocereus carmaguensis from seed:

The same requirements as most other Bolivian Trichocereus species. Seeds need light to germinate and seedlings prefer mineral substrate. Sprinkle the seeds on top of the soil and put the pot/container in a warm room (25°-29°) and make sure it´s not getting too hot in there. As soon as all the seeds have germinated, keep a close eye on the temperatures because they can die from heat quite easily. Temps should not go above 30° Celsius! Especially in closed containers, temps can be substantially higher than in the room around them.

Where to get seed:

There are not many seed sources for Trichocereus camarguensis available right now. I have received some top notch seeds from the current harvest by a friend this year. Check out the shop to buy some Trichocereus camarguensis seeds.

Hybrid Culture:

Trichocereus camarguensis is used extensively in hybrid culture because they flower early on and produce a beautiful flower. Because of that there are many camarguensis hybrids with a flower other than white.

Similarity to Trichocereus strigonus

Trichocereus camarguensis and Trichocereus strigonus are extremely similar. The difference is that Trichocereus camarguensis only has yellow spines, while T. strigonus has yellow and red colored forms. In addition, T. strigonus has much more spines and is a bit taller.

Trichocereus shaferi (Echinopsis shaferi)

Trichocereus shaferi (Echinopsis shaferi)

The name Trichocereus shaferi was described by Britton and Rose in the 1920s and lacked some important information. However, there were some later descriptions by Friedrich Ritter, Curt Backeberg/Rauh and Werdermann that went more into detail.

Trichocereus shaferi pups from the base and reaches a size of 1-1,5 meters. The plant grows halfway prostrate or leaning over and has between 15 and 20 ribs. Britton and Rose gave an average number of 12 ribs, which is dramatically different from the data that were given in later descriptions. The maximum diameter is 5-12 centimeters and the color is a gray/dark green, which you can very well see on the pictures that were provided by Trout. The ribs are 0,5-1 centimeters high and there are substantial furrows .

The areoles on Trichocereus shaferi are white felted and 1-6 mm in diameter and up to 1,2 centimeters apart of each other.

Spines: The spines of Trichocereus shaferi are yellow, very fine and needle-like with a slightly dark-brown tip. It has 7-10 radial spines (up to 1 cm long) and 1-3 middle spines (1-2 cm).

Flower: Very round flower. White. Trichocereus shaferi flowers from the upper part/apex and Britton and Rose gave a size of 15-18 cm.

Fruit: The fruit has very dominant white hairs, as you can beautifully see on the second picture. The edible fruit is round and 3-5 cm in diameter. Green in color with reddish/green scales.

Origin: Ritter encountered this plant near Leon near Jujuy at around 1500-1800 meters growing on rocky slopes. Britton and Rose gave San Lorenzo in the provence Salta at 1800 meters as the location of the typus. Ritter considered his collection in jujuy to be a regional variety but didnt really follow up on it. His collection name was FR41 and there is a large number of seeds that gotten into the collections of cactus fans all around the world.

Where to buy seeds and plants of Trichocereus shaferi? Well, it´s rare and you might come across them on eBay. Like I already mentioned before, I bought a large plant with this name a few years ago and we´re waiting for it to flower next year. Some seed stores and cactus nurseries have them in stock every once in a while, but it´s a rather rare species and it´s not available from South America. I am sure there are some collectors that offer seeds from their collections sometimes, but it´s probably a little bit hard to find and luck has a lot to do with it. If I´d be looking for this species, I´d write emails to Kakteen Haage, Kakteen Uhlig, Succeed, Sacred Succulents and hope for the best. You can also try making a post in our Trichocereus Facebook group but I´ve never really encountered one there. But it cant hurt to ask.

Trichocereus andalgalensis / Echinopsis huascha v. andalgalensis

Trichocereus andalgalensis / Echinopsis huascha v. andalgalensis

Synonyms: Echinopsis andalgalensis, Lobivia andalgalensis, Cereus andalgalensis, Cereus huascha var. rubriflorus, Trichocereus huascha var. rubriflorus

Trichocereus andalgalensis has a weird & complicated history. The name first appeared in 1893 in the MONATSZEITSCHRIFT FÜR KAKTEENKUNDE, which is a German publication about cacti. The plant was originally introduced into the world of taxonomy as a red flowering variety of Cereus huascha (Trichocereus huascha). In his book, Schuman mentioned that Weber described this plant and regard the red flowering variety of Cereus huascha (now Trichocereus huascha) to be a separate species called Cereus andalgalensis. The plant is very similar to Trichocereus huascha and was recently declared to be synonymous with Trichocereus huascha. The current taxonomy tends to merge relative plants together in larger, more variable species and I absolutely agree with that. The species was originally found near Andalgala, has very fine yellow spines and is sprouting from the base.

Now back to the time when Cereus andalgalensis was first desctribed. Back then, a cactus enthusiast and taxonomist called Spegazzini somehow got the idea that the name Cereus andalgalensis would actually be about a small Lobivia that was found near Ancasti. Which was absolutely not the case, since Trichocereus Andalgalensis is a columnar cactus that grows very much like Trichocereus Huascha (but does not get as big) and not a small clumping Lobivia.

And when Britton & Rose wrote their cactus manifest called THE CACTACEAE, they did not realize that Spegazzini described a completely different plant and published the troubled description in their as Lobivia andalgalensis B&R and declared that Lobivia to be synonymous with the red flowering variety of Trichocereus huascha (Trichocereus andalgalensis), which back then was called Cereus huascha Rubriflorus. Now, there were two different plants that were considered to be the same plant. And one (the Lobivia) did absolutely not fit into Weber´s old description of a columnar cactus.
Weber originally gave Andalgala in the province Catamarca to be the type location of the plant. Exactly where Rauh found a small clustering Trichocereus that fit into Webers old description and which was most likely the original origin of Trichocereus andalgalensis, which was back then still called Cereus andalgalensis.

Description: Trichocereus andalagensis is bright green in color and reaches a maximum diameter of up to 6 centimeters. The shoots can reach a maximum height of 10-40 Centimeters. It´s pretty typical for this plant to sprout abundantly from the base, even at a relatively young age.

Ribs: Trichocereus andalgalensis has 10-18 Ribs that are up to 5 mm high and between 5-10 mm wide. The areoles are brown and declining in color with age. The areoles are between 1-3 mm in diameter and 5-10 mm apart of each other.

Spines: The spines of Trichocereus andalgalensis are yellow, very similar as the ones on Trichocereus spachianus. All spines are very fine and needle-like. It has 7-15 radial spines that can get up to 1,5 mm long and 1-2 middle spines, which are 1-4 cm long.

Flowers: The flowers are usually red and up to 8,5 cm long, what makes the flower of Trichocereus andalgalensis one of the smallest flowers on a Trichocereus species. The flowers are and have a lot of brown hairs. There also is a variety with a yellow flower. The yellow variety is called Trichocereus andalgalensis var. flaviflorus and the red flowering one is Trichocereus andalgalensis var. rubriflorus.

Where to buy seeds or plants of Trichocereus andalgalensis?: There only are a couple of sources where you can get seeds of Trichocereus andalgalensis. One is Sacred Succulents, which was offering very viable seeds of this amazing cactus. Köhres has them in stock sometimes too though I have no idea how the germination rate of those is. Apart from that, I am not aware of any commercial sources that sell this seed. If you have a shop and have them in stock, you can let me know and I´ll add you to this page. You can also make a posting about Trichocereus andalgalensis in our Trichocereus Facebook Group. It´s not a very common type, but chances are some of our older members might still have some from the time when Friedrich Ritter sold seeds of this plant as FR 428.

Trichocereus arboricola (Echinopsis arboricola)

Trichocereus arboricola (Echinopsis arboricola)

Current name: Echinopsis arboricola (Kimnach) Mottram

Origin: Bolivia, Argentina, Type locality: Tarija in Bolivia, 600-1000 meters altitude

Trichocereus arboricola is more of an Epiphyte instead of a normal Trichocereus and is often grown like a hanging basket cactus. It often starts off as a columnar cactus, but goes prostrate as soon as it reaches a certain size. You can grow it in a hanging basket or like a columnar Trichocereus.

It’s a very tender cactus with a shiny, bright green color and very thin, needle-like spines. It can reach a total size of more than a meter and up to 5 centimeters in diameter. It usually has 10+ ribs and has very small, very subtle bumps over the areoles, which are slightly felted. The areoles are up to 5 mm apart from each other. It develops aerial roots and has very fine hair on the areoles. Trichocereus arboricola has between 10-16 spines, which are very thin and similar to the spines on some Cleistocactus species.

Trichocereus arboricola is a night flowering species and has a very beautiful flower, which is very large for its size and white in color. It has a very delicate and noble flower.

Trichocereus arboricola is a fairly new species and was described in 1997. Because of that, it’s not included in many old cactus books.

Trichocereus lamprochlorus / Echinopsis lamprochlora

Trichocereus lamprochlorus / Echinopsis lamprochlora

Trichocereus lamprochlorus is strange species that needs investigation. There are various species associated with Trichocereus lamprochlorus / Echinopsis lamprochlora, such as Trichocereus purpureopilosus and some forms of Trichocereus candicans that are considered to be synonymous with it. The species was merged into the genus Echinopsis during Friedrich & Rowley´s merger in 1974 and named Echinopsis lamprochlora (Lemaire).

Synonyms: Trichocereus lamprochlorus, Cereus lamprochlorus, Cereus nitens salm-dyk, Trichocereus candicans, Trichocereus purpureopilosus,

The situation around Trichocereus lamprochlorus is complicated because the original description of Cereus lamprochlorus (Lemaire) and the Trichocereus lamprochlorus that we know today are two different plants. It is unknown what kind of plant Lemaire was describing as Cereus lamprochlorus, but the description differs greatly from our modern Trichocereus lamprochlorus. One of the two plants associated with this name is a medium sized Trichocereus that pups very strongly from the base and grows in groups of many side-arms. The other one is a classical columnar cactus that grows upwards and tends to get a lot bigger than the other type. Both are totally different types of cacti, but were at some point, described as the same plant. The columnar growing type of this plant is the one that´s generally accepted as Trichocereus lamprochlorus today. Trichocereus lamprochlorus belongs to a very variable complex involving numerous closely related or visually similar species. Despite the fact that the two plants known as Trichocereus lamprochlorus are different types of cacti, they might still belong to the same group of plants and just be examples of different forms belonging to different populations. It is also possible that the columnar version is what´s shown on the photos below, and the smaller clumping cactus is the forum that was later described as Trichocereus purpureopilosus. Both of them are related and show visual similarities, but differ greatly in regards to their type of growth.

These pics were shot in Tiatako, Cochabamba, Bolivia. They show a regional form related to the type that we regard as Trichocereus lamprochlorus today. It has up to 15 ribs, strong spines, a reddish touch around the spines, a very bright green epidermis, 10-15 radial spines and 4 middle spines. The flower of the originally described plant was not know.

Britton & Rose already had problems with the two mixed up plants mentioned before and tried to get to the bottom of it. Without success. The other version of Trichocereus lamprochlorus was also described as “Trichocereus neolamprochlorus”. It is a plant that´s very similar and even related to  Trichocereus candicans. This plant stays relatively small, pups from the bottom, has a bright green epidermis that later changes to a sickly looking yellow color. The plants can get up to 10 centimeters in diameter, have between 8-12 ribsm, spines with a reddish touch. Its flowers are up to 25 centimeters large, white, covered with black wool. This type originally grows around Cordoba in Argentina and is a different type of cactus, one which is close to Trichocereus candicans. Due to the chaotic history, the nomenclaturic situation around these plants is convoluted.T

Trichocereus schoenii / Echinopsis schoenii

Trichocereus schoenii / Echinopsis schoenii

Trichocereus schoenii , also known as Echinopsis schoenii under current nomenclature, is a south Peruvian Trichocereus species that Backeberg described and named after E. Schön, who assisted him financially on his trips. Mr. Schön was from Arequipa, which is where one of the most important habitats of this species is. However, the species is not limited to that area and grows nearby other South Peruvian Trichocereus species. Trichocereus schoenii usually grows in the company of some Corryocactus species and there are also some other Trichocereus species that grow at the same sites.

Trichocereus schoenii resembles Trichocereus santaensis, but differs from it by the long central spine and a slightly different areole shape and rib shape. You need to look very closely to tell them apart, and it´s usually the typical spination that allows you to recognize it as what it is. It´s a very rare and beautiful species which is very rare in cultivation. The plants that are available are usually mislabeled and are usually identified as Trichocereus cuzcoensis or Trichocereus knuthianus.

Trichocereus schoenii is a plant that roughly belongs to the Trichocereus cuzcoensis complex, but there are many differences and I hope to see some cladistic studies about this species one day. The species usually has seven ribs (as seen in the photos) and the spines can get up to 8 centimeters long. You can read a more detailed description including some habitat photos in my book.

Trichocereus strigosus / Echinopsis strigosa

Trichocereus strigosus / Echinopsis strigosa

Trichocereus strigosus is a plant from the genus Trichocereus. Its status is questionable and it is sometimes also listed as Soehrensia strigosa. I treat it as a correct species in the genus Trichocereus. It is closely related to Trichocereus vatteri and only differs from it by the flowers. Visually, both species are very hard to differentiate and are mostly synonymous.

Synonyms: Cereus strigosus, Echinopsis strigonus, Cereus myriophyllus, Trichocereus strigonus,

This plant grows in direct neighborhood of Trichocereus candicans and was cataloged by Gilles in 1833. But back then, the plant was not described until 1834 when Salm-Dyck took the effort to write a complete description. Trichocereus strigosus and Trichocereus candicans both grow around Mendoza. The original name was Cereus Myriophyllus (Gilles) but it was changed to Trichocereus strigosus because it was based on a nomen nudum and that´s why Salm-Dyck´s description has priority over the older name Cereus Myriophyllus.

Flower: Up to 20 centimeters large, white. Trichocereus strigosus is a night flowering species. It also is self-sterile, what means that you need pollen from another donor to produce seeds. Please not that there is a white form of Trichocereus strigosus. The white flowering variety of this plant grows at around 1600 meters altitude. The plant is pupping from the base and only reaches around 60-65 centimeters in height.

Ribs: Trichocereus strigosus has 15-20 ribs and the shoots have a maximum diameter of 5-8 centimeters.

The areoles are white/beige felted and reach a maximum diameter of 5 mm. Every areole are approximately 3-6 mm apart from each other.

Spines: Yellow, very thin and fine spines, up to 3 centimeters long, 10-15 radial spines and 2-5 middle spines that can get up to 5,5 centimeters long. The plant has very long and fierce spines.

In addition, there are some other forms/varieties. One of them was originally known as Trichocereus strigosus var. flaviflorus and only occurs in Famatina, Province La Rioja in Argentina. This type has a yellow flower and is day flowering. The flowers are between 12-14 centimeters large. The yellow flowering variety grows a couple hundred meters below the white flowering one. In addition, the yellow flower is shorter.

Cultivation: The species is very rare in cultivation, though it sometimes shows up in cactus collections all around the world. The plant should be kept relatively dry, though it can be watered in the summer when it´s pretty hot. As it grows in the neighborhood of Trichocereus candicans, it requires similar conditions. Trichocereus strigosus likes getting a fair amount of sun light but shouldn´t be baked in full sun all day long. They usually grow in semi-shade and can form amazing clusters.

Winter protection and frost tolerance: Trichocereus strigosus is able to take a light amount of frost but everything lower than -5° Celsius is dangerous and can lead to permanent damage or death. Plants need to be kept completely dry if the temperatures drop below 10° Celsius/50° Fahrenheit and it´s best to keep them in a bright, well ventilated area. The minimum average temperature is 10° Celsius.

Seed germination: The seed germinates very easy, if it´s actually fresh. Especially with those rarer Trichos, there are problems regarding the viability of the seeds. I think Succeed has them in stock too and if possible, ask the seller in advance if he knows how old the seed is. That´s a good rule of thumb anyway and these days, I do it for all my seed orders.

Trichocereus candicans (Echinopsis candicans)

Trichocereus candicans (Echinopsis candicans)

Trichocereus candicans is a species from the genus Trichocereus that originally grows in Argentina.

Current name: Echinopsis candicans (Gillies ex Salm-Dyck)

Synonyms: Cereus candicans, Echinocactus candicans, Echinocereus candicans, Echinopsis candicans, Helianthocereus candicans, Trichocereus pseudocandicans, Trichocereus tenuispinus, Echinopsis candicans var. tenuispinus, Cereus candicans spinosior, Trichocereus neolamprochlorus, Trichocereus gladiatus, Trichocereus candicans var. gladiatus, Trichocereus rubriflorus, Echinocactus dumelianus, Cereus Candicans var. spinisior, Helianthocereus pseudocandicans and some forms of Trichocereus lamprochlorus

First of all, this species is a mess. There are totally different types of plants floating around in the collection and I am not even counting the hybrids yet. There were numerous taxonomists in the past 100 years messing around with Trichocereus candicans and I am not really happy with the current taxonomy either. There originally were a couple of different subspecies like Trichocereus candicans & Trichocereus pseudocandicans + the closely related species Trichocereus lamprochlorus + neolamprochlorus. Trichocereus lamprochlorus was once again divided from Trichocereus candicans…and for good reasons.

Trichocereus candicans is a small and compact columnar cactus that builds clusters and grows approximately 75 centimeters tall- The plant usually has a yellowish skin color and grows in clusters up to 3 meters wide. The columns are 8-15 Centimeters thick and have between 9 and 11 Ribs. Areoles are pretty big and white felted and up to 2 centimeters apart of each other. Trichocereus candicans has 10-12 Radial Spines that are up to 4 centimeters long and 4 middle spines that are up to 8 centimeters long.

Flower: Most specimens of Trichocereus candicans have white flowers, but this is a heavily bastardized species in nature and I´ve seen various populations that had all kinds of flower colors and everyone of them was more beautiful as the other. And they had all kinds of flowers…yellow, red, white, you name it! Regularly, the flower is white and reaches a size of up to 20 centimeters  (and some forms or varieties even more). The flowers have a very nice smell and attract all kinds of insects. Because of its excellent flower, Trichocereus Candicans is a perfect plant for hybrid breeding. The flower looks amazing and accepts pollen of most other Trichocereus, including the San Pedro cacti. Because of that, it´s a great candidate to breed colored flowers into the whole San Pedro group.

Trichocereus candicans is Night flowering. Besides, it is self-sterile, what means that you need pollen from another donor to produce seeds.

Origin: Argentina. Around Mendoza and Cordoba. San Juan, Catamarca, La Rioja.

Just like I already mentioned, the species is very variable and is also close to Trichocereus lamprochlorus. There are intermediates that show traits of both species and it´s nearly impossible to give a definite ID. There are natural hybrids between Trichocereus candicans x Trichocereus huascha and Trichocereus candicans x Trichocereus strigosa.

CITES: Trichocereus candicans is in Cites APPENDIX II.

Varieties & Cultivars: Trichocereus candicans var. gladiatus (with very large flowers), Trichocereus candicans var. robustior, Trichocereus candicans var. rubriflorus, Trichocereus candicans Gröner Hybrids (which is a hybrid between T. candicans x Pseudolobivia, which flowers very early on), Trichocereus candicans var. tenuispinus, Cantora hybrids (which is a cross between Trichocereus candicans and Echinopsis toralapana), and so on.

Trichocereus candicans is a very good species for grafting or hybrid culture. There are certain hybrids with extremely beautiful flowers called CANTORA. Those hybrids are one part Trichocereus candicans and one part Echinopsis toralapana.

Many taxonomists would agree that this species an extremely variable plant that makes many problems. And while I agree with that, it´s also caused by the chaos that was caused by the large amount of different types that were all merged into this huge species “Trichocereus candicans”.  Because there are so many different types available on the market, there are countless atypical plants that grow more columnar than standard Candicans´or that have very short spines instead of the long spines that most candicans are known for.

Cultivation: Trichocereus candicans is very easy in cultivation. It is an excellent grafting stock that is known for its great frost tolerance, but the plant is so beautiful that you can also grow it just because it looks cool. Especially the colored flower hybrids around La Rioja are amazing and I can only recommend you this amazing cactus. The plant takes many years until it flowers but there are some hybrids called Groener candicans that are basically the result of an open pollination between candicans and Pseudolobivia, which flower very early on within the first five years. Those hybrids were named after the grower who raised and distributed them. If you can get those hybrids, you wont regret it. But they are rare and should only be watered when it´s hot. Because of that, the plant does not get any water in between October and April. In Europe, you can overwinter them in a bright place with lots of fresh air at a temperature of approximately 10° Celsius. That´s the minimum average temperature and they do not need any water until the temperatures are starting to rise again.

Cultivation from Seed: Trichocereus Candicans is very easy from seed and requires the same treatment as any other Trichocereus. They are really frost resistant and can sometimes withstand short night frosts of down to -8° Celsius/17.5° Fahrenheit. I would not want to test it out though, because it always depends on the general health of a plant. The minimum average temperature is around 10° Celsius/50° Fahrenheit. The seeds will start germinating at temperatures between 24-30° celsius and require very little water to germinate. They are relatively uncomplicated to grow but I had the best experiences with a soil that was purely mineral.

 Propagation: The plant is propagated by live Cuttings and seed.

Seed & live cutting sources: I am working on getting this species in my shop. As soon as I get high quality seeds of this one, I will let you know.

Trichocereus candicans / Echinopsis candicans

On this beautiful specimen you can see how similar Trichocereus candicans can get to Trichocereus taquimbalensis. However, Trichocereus candicans tends to have a higher spine count and a different spination. The spines on Trichocereus taquimbalensis are crooked and look very different. The epidermis of both Trichocereus candicans and Trichocereus taquimbalensis are waxy green. There are forms of both that are not waxy and that makes identification difficult at times. Trichocereus candicans does not get as tall as Trichocereus taquimbalensis and if you see them forming lower colonies instead of columnar cacti, the plant is probably a Trichocereus candicans. This form is also similar to what was described as Trichocereus gladiatus.

Trichocereus peruvianus Echinopsis peruviana

Trichocereus peruvianus Echinopsis peruviana

Trichocereus peruvianus or Echinopsis peruviana is a columnar cactus that can get up to 4 meters long and reaches 20 centimeters in diameter. It´s also called the PERUVIAN TORCH cactus and is native in Peru. Britton and Rose – The Cact. II, S.136 /192

Trichocereus peruvianus Collana Pichu Peru Echinopsis macrogona

Description of Trichocereus peruvianus:

Most regional forms belonging to this species have a frosted blue color and grow between 6-9 ribs. Its flowers are white, though there are some close relatives that have a different flower color (Trichocereus tulhuayacensis). It usually grows upright, but sometimes grows prostrate hanging down from cliffs and rocks.
The size and color of the spines varies greatly, but most of them have about 6-8 honey-colored to brown spines that can reach about 4 centimeters in length. The areoles are brown to beige-felted and up to 2,5 centimeters distanced from each other. The Spines do NOT have a knobbed Base. The spine color is one of the key traits if you attempt to tell it apart from Trichocereus macrogonus. We write more on Trichocereus macrogonus in that particular chapter.

Trichocereus macrogona / Echinopsis macrogona aka T. peruvianus

Trichocereus peruvianus Matucana Echinopsis peruviana
A Peru at the type locality in Matucana.

Echinopsis peruviana flowers very easily as soon as it reaches a certain size and the plant is very easy to cultivate. Some of them have a distinct V-Notch above the areoles, but not all and it´s not a trait that is reliable for identification.

Cultivation of Trichocereus peruvianus / Echinopsis peruviana:

Trichocereus peruvianus can be grown from seed 0r propagated by cuttings. Seeds need to be sprinkled on top of the soil because they require sunlight to germinate. The seeds are tiny and only a few mm large and have a long viability. Usually, the seeds can stay viable for up to 10 years or above, though that depends on many factors. The Seed needs to be stored in a dry and cold environment to guarantee maximum viability.

The cactus can also be propagated through cuttings and it´s very easy to root. But make sure that the cuttings are not smaller than 20 centimeters because that stunts the growth tremendously.

The flower of Trichocereus peruvianus / Echinopsis peruviana:

The flower is white and reaches as size of up to 25 centimeters. Trichocereus peruvianus is a night flowering species.

Peru (around Matucana). Trichocereus peruvianus is the dominant Trichocereus species in Matucana.

Plants that are closely related or are synonymous with Trichocereus peruvianus:

Trichocereus tacnaensis, Trichocereus puquiensis, Trichocereus santaensis (some of the plants around the Santa Valley belong to Tr. pachanoi though), Trichocereus tarmaensis (closely related to Trichocereus cuzcoensis as well), Trichocereus macrogonus, Echinopsis macrogona, Trichocereus f. Ancash, Trichocereus sp. Ayacucho, Trichocereus giganteus, Trichocereus longispinus, Trichocereus sp. Pamacoche, Trichocereus sp. Matucana, Trichocereus rosei,

Trichocereus peruvianus and Trichocereus pachanoi are sister species and closely related. Some field botanist considered them one large and variable species and there are countless intermediates and hybrids that could be placed in either species. Around 1950-1980, some authors came up with a large number of unnecessary species names and most of these plants would fit into the description of Trichocereus peruvianus as well.

Culture of T. peruvianus:

The culture of Trichocereus peruvianus is not very hard. The plant has very similar requirements as other Trichocereus species like Trichocereus macrogonus or Trichocereus pachanoi. Trichocereus peruvianus is an extremely frost resistant plant that can thrive in the most difficult environment. Some of its forms grow columnar while some others are creeping/prostrate. In their natural habitats, they even hang down on hills or rocky slopes. When watering cacti, the soil should not stay wet for more than a couple of hours because it greatly increases the probability of rot. Cacti need a substrate that dries out fast and too much water is often deadly for them. Apart from a little bit of water here and there, you should only water Trichocereus peruvianus when it´s warm. During the hot growth-season, they can take daily or weekly watering and like to be fertilized on a 7-14-days schedule. I even fertilize weekly during the main season, but that also depends on your personal way of growing cacti. It’s best to use a mineral substrate like Pumice or Lava, with additives like Coir, Sand, Sowing Soil, Expanded Clay etc. Just make sure to add in a very small part of Coir or Humus because it helps to solidify the soil and increases the cactus ability to take in nutrients. I personally love Lava and Pumice and the plants enjoy it very much! Echinopsis peruviana aka Trichocereus peruvianus likes a sunny place in half-shade, but not full sun. They can take it if they are used to it, but it increases the risk of sunburn. Especially directly after the winter period when they are not used to it yet.

Winter & Frost Protection: Trichocereus peruvianus is a relatively frost hardy cactus. It’s usually not a problem for it to take take a little night frost here and there and is tolerant down to -9° Celsius. But that’s really the limit and I would not be comfortable to push it below that. There are always plants are less frost tolerant than others and you never know where the limit for your plant is going to be. A plant that spent its life in a heated greenhouse, will die very soon if you suddenly start exposing it to cold winter frost. The cacti need to be hardened up and in a good general health. In my greenhouse I overwinter Trichocereus at 1° Celsius between December and March.

Minimum average winter temperature:

The ideal average winter temperature for Trichocereus peruvianus is 10° Celsius. That´s close to their natural winter period in habitat. Trichocereus peruvianus can compensate short frosts down to 15.8° Fahrenheit every now and then but you should take care that it has an average temperature of around 50° Fahrenheit.

Winter storage & Winter Protection for Trichocereus:

Trichocereus peruvianus needs fresh air during the wintertime if you want to overwinter the plant inside. It also needs light and the soil has to be completely dry, to make sure that the rootstock does not rot. This is important because that’s exactly what happens in the habitat during the winter time. Trichocereus peruvianus can deal with low temperatures as long as its dry.  Of course all those overwintering-rules only apply of you live in a country with hard winter frost down to -20° celsius and lower. If you live in a warmer country such as Australia, this certainly is not a problem for you and water or high air humidity are the bigger problem then. I also know many growers from the CA area in the USA, and they usually get their plants over the winter without problems, if they do nor get surprisingly cold frosts. Leave your Trichocereus peruvianus in a bright room, give it a little bit fresh air every now and then and make sure to keep the temperatures below 10° Celsius. As soon as you put them in a heated room, they will require regular waterings and light or they will die quickly. In addition they will etiolate. If kept dry, the water requirements during the winter are minimal though. The minimum temp in Fahrenheit is 50° Fahrenheit. No water should be given between late autumn (October-early May) unless you grow them in a heated place, eg greenhouse or house.
If you are lucky enough to have a greenhouse, you can take out most Trichocereus in early March, but you should also check the maximum frost tolerance of the species you take out. There are many cacti that need higher temperatures to stay healthy.

Germinating Trichocereus peruvianus seeds:

Just like Seed of other Trichocereus species, Trichocereus peruvianus seeds need light to germinate. I usually prepare a mix of Pumice, Lava, Coir, and Sand and and sprinkle the seeds on top of the soil. Make sure not to knock off the sowing container/pot because that would probably bury the seeds and that’s never a good thing. Buried seeds often do not germinate due to the lacking light or they germinate deep inside the soil and die. So yeah, sprinkle them on top of the soil and make sure that the temperatures are between 26° and 30° Celsius. Make sure to add in enough water to start the germination process. However, it does not take a lot of water to kick start the germination and it’s always better to give very little water early on because you can always add in some more. But if you add too much water in the beginning, it cannot be undone without risking to wash or soak away the seed with the excess water. With a syringe, excess water can be removed from the sowing container.  Put the sowing containers in a bright and warm place and be patient. A window sill works perfectly. You can also use a LED lamp to give them enough light to germinate and I can recommend that very much because it increases the germination rate. Adding a decent LED Lamp (like 100 Watt and above) will increase germination rates dramatically and the plants are healthier and grow faster.

Germination of seeds and why some seeds don´t germinate

The problem with seeds is that some shops resell seed from South America wholesalers that sell over-aged seed. So the shops might not know about the bad germination rates that their seeds have and that´s a real problem with Trichocereus peruvianus seed on the market. If you did everything I just mentioned and your seed does not germinate within like 2-6 weeks, it´s most likely old garbage. It does not help to keep it wet for longer than that because that’s not how germination of cactus seeds works. Instead, you let it dry and start another cycle once the soil is completely dry.  It does not help to keep dead seed in germination chambers for 6+ weeks. You will just grow Algae and Moss. Another problem that you can get with commercial seed is that there´s a lot of misidentified seeds of this species available on the market. The people who collect these seeds usually don´t have access to literature and that´s why the misidentification rate is extremely high. . Many Trichocereus cuzcoensis are sold as Trichocereus peruvianus and that´s a big problem for the seed market.

My best recommendation is that if you can get in touch with the seed producer, send them a message and ask about a pic of the mother plant. That way, you can minimize the risk of getting mislabeled seed.

Seed Viability of Echinopsis peruviana/ Trichocereus peruvianus:

The seed of Trichocereus peruvianus is viable for many, many years. I sometimes successfully germinate seeds that are more than 5-10 years old but it always depends on the storage and the seed. Some are dead within a couple of months while some can even stay viable for decades, like Ariocarpus seeds. The bigger the seed, the longer they are viable btw. Rebutia are dead within a couple of weeks, Trichocereus & Echinopsis 5-10 years, Ariocarpus 10+ years, Echinocereus (5-10 years), Lophophora (2-5 years at max).

How to differentiate Trichocereus peruvianus and Trichocereus cuzcoensis? 

The swollen spine bases of Trichocereus cuzcoensis are the main trait that Britton and Rose used to tell them apart. Trichocereus peruvianus does NOT have swollen spine bases. There are many intermediates and forms in between the two, but in regards to the original description that’s the most important trait. In addition, Trichocereus cuzcoensis only grows in Cuzco. There are relatives of Trichocereus cuzcoensis that can be found in other parts of Peru however, e.g. Trichocereus knuthianus, Trichocereus schoenii, etc

How to differentiate Trichocereus peruvianus and macrogonus

Both species are probably synonymous. Trichocereus macrogonus was used for plants with dark brown or red spines, while plants with different spine color were seen as Trichocereus peruvianus. The original description of Trichocereus macrogonus is ancient, lacked important traits or information such as country of origin and the original plant was never found again afterwards. Technically, Trichocereus macrogonus is the older name and might replace Trichocereus peruvianus as official name one day (IF the problematic description will be accepted). Some authors have already started to use this system, but is unclear if it will be accepted officially. Modern taxonomy moves towards fewer species, with a larger number of subspecies or varieties and I completely support that.

Für TRICHOCER. PACHANOI geben BR. & R. als Typusort an CUENCA, Ecuador,
für TRICHOCER. PERUVIANUS MATUCANA, Peru. In Wahrheit liegt nur
eine Art vor. ROSE war jedenfalls ungenügend orientiert Über die große
Variationsbreite dieser Art in Bestachlung und Areolengröße. Man kann
TRICHOCER. PERUVIANUS nur als eine Form der PACHANOI ansehen, die entweder
allein oder mit letzterer an gleichen Stellen wächst von Ecuador
bis Mittelperu, und zwar mit Übergangsformen in einander. Für die Form
PACHANOI sind typisch Ar. von 3-5 mm Dm., feine Rst. von wenigen mm
Länge und meist nur 1 Mst. von wenigen mm bis zu etwa 2 cm Länge. Oft
fehlen die St. völlig, oder sie sind nur an jüngeren Pflanzen vorhanden
und fehlen an älteren Köpfen. Formen, welche Ar. von etwa 5 bis
nahezu 10 mm Dm. haben und stärkere St., von denen der mittlere meist
über 2 cm Länge hat und selten bis über 10 cm Länge erreichen kann,
wird man als FORMA PERUVIANUS bezeichnen. Die Zahl der St. kann bei
beiden Formen bis auf etwa 10 gehen, die Anordnung der St. und das
Größenverhältnis zwischen Rst. zu Mst. ist bei beiden Formen dasselbe,
Mst. sind nur einer vorhanden, seltener 2-3. Die St. beider Formen
sind nur unterschieden durch Länge und Dicke; es mag also vielleicht
für beide Formen nur je ein Allel eines einzigen Gen vorliegen, so daß
eine Weiterführung des Namens PERUVIANUS als forma wohl nur aus Tradition
zu rechtfertigen ist, wegen der Zweiteilung der Art durch Br. & R.,
denn solche Erbformen pflegt man an sich nicht taxonomisch zu benennen.
Da eine genaue Bl.-Beschreibung nie erfolgte, gebe ich hier eine

Trichocereus terscheckii (Echinopsis terscheckii)

Trichocereus terscheckii  (Echinopsis terscheckii)

Origin: Trichocereus terscheckii  is a variable species that is a catch-all name for a variety of different forms, some of which form intermediates with other species like Trichocereus atacamensis, Trichocereus taquimbalensis, Trichocereus validus and others.

Trichocereus terscheckii grows around the south of Bolivia, North Argentina (Catamarca, Tucuman, La Rioja, Jujuy, San Juan, Salta) and there are many intermediates between Trichocereus terscheckii, Trichocereus atacamensis, Trichocereus pasacana and Trichocereus validus and some of the lesser known species. The genuine Trichocereus validus is probably just a Bolivian form of Trichocereus validus, but unfortunately it is not often found in nature.

Trichocereus eerdermannianus is actually an intermediate species in between Trichocereus taquimbalensis and Trichocereus terscheckii. Overall, this is a very complex and highly controversial group of plants and only DNA testing can help to clean up the family tree that is hidden inside those beautiful tree-like plants. Personally, I think that all those Andean Trichocereus species are members of a very variable group of plants that belong together and should be treated like that.

Below you can find a description of Trichocereus terschecki, but since there are so many regional forms, there can be plants that don´t fit perfectly, but which still belong to that complex somehow. In addition, there are many natural hybrids and Trichocereus terscheckii hybridizes relatively easy.

Synonyms: Echinopsis terscheckii, Cereus terscheckii, Pilosocereus terscheckii, Cereus fulvispinus, Trichocereus validus, Echinopsis valida, Trichocereus werdermannianus, Cereus werdermannianus, Echinopsis werdermannianus, Cereus validissimus. Besides, some forms of Trichocereus pasacana and Trichocereus atacamensis are synonymous with Trichocereus terscheckii too.

Varieties: In the past, there were descriptions of a plant called Trichocereus terscheckiioides which differed in regard to the phenotype and Trichocereus terscheckii var. montanus.

Cultivation: Trichocereus terscheckii is an amazing plant in culture. They grow very slow compared to other Trichos and don’t require a lot of water. I usually try to give them as much free root run as possible, what is important for their ability to flower. Their growth rate depends on many things, like how they are grown, hoch much water & fertilizer they get, and so on. Plants in habitat grow very slow and sometimes take 50 years to reach a good size. Their mature form is totally different to what they look like as seedlings.

Description: They start off as typical columnar cacti that are pretty fat for their small size and get very big and tall later on. It takes many years till this species produces its characteristic side arms. Trichocereus terscheckii can reach a size of 10-15 meters and a diameter of up to 60 centimeters.

Ribs: 8-15

Areoles: Approx. 2 centimeters in diameter and up to 3-4 centimeters apart from each other.

Spines: 10-16 spines, yellow and up to 10 centimeters long

Flower: White, 15-22 centimeters long, 14 centimeters wide, petals up to 8 centimeters. Tube covered with brown, woolly hair. The variety Trichocereus montanus was said to be less branchy and grew more like a typical columnar. Besides it had a larger diameter. I personally do not accept any varieties because I think that this is just a crazily variable species.

Trichocereus terscheckii and Frost: Trichocereus terscheckii is quite cold hardy and even survives in some areas in the United States. Personally, I would recommend a minimum average temperature of 10° Celsius/50 Fahrenheit, but they are known to survive short night frosts without a problem. However, temperatures should never go below -9°/15.8 Fahrenheit, especially not when they have wet feet. It is also important to keep away rain and moisture during the cold months, because the rain is probably a bigger problem that the cold temperatures. Those plants can stand the cold, but as soon as it´s cold and wet, it´s starting to get dangerous.

Trichocereus terscheckii from Seed: This species is very easy from seed. It requires the same treatment as any other Trichocereus species, but keeping the seed cold over night can help to break up the dormancy. The seed is usually viable for many years and I am sure you can get some Germination as long as the seed does not get older than 10 years. But you get the best germination rates within the first year. Make sure not to sow out too many of them at once, because they become quite fat and need enough space.

Trichocereus terscheckii Seed & live cutting sources: This plant sometimes shows up on Ebay as live cuttings, plants or seeds. You can get a nice strain of Trichocereus terscheckii here in my shop:
