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.

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.

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.

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.

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 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 sp. ‘Isla del Sol’ (Echinopsis)

Trichocereus sp. ‘Isla del Sol’ (Echinopsis)

This population from the Bolivian island ‘Isla Del Sol’ belongs into the distant complex of Trichocereus bridgesii / Echinopsis lageniformis. However, it is currently discussed whether or not this plant is actually a different species and DNA testing is required to look into its status.  Sacred Succulents visited this population during their Field Trips and made some amazing photos. I also have some sick photos of it in my first book.

 

BK08601.1 Trichocereus Isla del Sol, Bolivia

Now, this is one of the most interesting Trichocereus species that were visited during the Sacred Succulents Field Trips! All the photos shown here are from Ben Kamm & Sacredsucculents.com! This was from the 2008 Field Trip and it is very similar to an intermediate between Trichocereus bridgesii and something from the Trichocereus cuzcoensis complex. Trichocereus cuzcoensis is mostly known for the plants in Cusco that were used to write the original description, but there are similar plants and relatives of Trichocereus cuzcoensis that can be found in other Peruvian states.

It also reminds me a little bit of Trichocereus knuthianus, which also belongs to the Cuzcoensis complex and has similar, massive areoles. Those plants are definitely very old…how they evolved exactly is not known.
Sacred Succulents gave away seed of this amazing species in 2008, but I do not know of anyone who raised some of them so far. If you happen to own this type, please let me know because it´s on my most-wanted list and I urgently need more pics of seed grown plants. The Isla Del Sol is an area that can be found in the southern part of the Lake Titicaca in Bolivia. It´s a wonderful area that is filled with ancient ruins and that screams “History”. I do not know if those plants were intentionally planted there or if they just evolved, but it´s definitely one of the coolest Trichocereus species out there.

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

The history of the PC Trichocereus clone – Predominant cultivar

The history of the PC Trichocereus clone – Predominant cultivar

I wanted to clarify some things about the PC Trichocereus clone. What it is, where it probably is from and what it isnt. The name is probably the most overused name in the history of Trichocereus culture. I personally hate it and spent days discussing the whole situation with friends or interested people in the Trichocereus Facebook group. If you hear the word PC in a Trichocereus group, JUST RUN. Log off, go outside and be in your garden. Still, if you actually wonder what those guys are actually talking about, I am happy to shed some light on this issue. Please keep in mind that I hate to use the name of this cultivar, strain or whatever you might want to call it and I will only mention this one time and one time only.

What does PC stands for? It originally means PREDOMINATE CULTIVAR. However, PREDOMINANT CULTIVAR would probably be more appropriate.

Now what is it really and is this all BS?

It is a clone, but there also are other plants grown from seeds that are probably coming from the same site this clone is coming from too. In California and parts of the USA, this clone is really common around parks, schools or gardens. It is very similar to most other San pedros, but it originally comes from Bolivia. This plant was originally collected by Friedrich Ritter and described as Trichocereus riomizquensis.

Trichocereus Riomizquensis 335This is the original photo from Ritter´s book. Do you see the white hairs on the flower and the way the areoles look? Well, keep in mind. You will need it later. Ritters official collection name of this plant was Trichocereus riomizquensis FR856 and they originally comes from Chyllas.

The original site is the Rio Mizque and we and my friends from Sacred Succulents visited the original site a couple of times.  It is extremely similar to Trichocereus pachanoi, but differs in substantial points like the hairs on the flowers and the overall rib structure. Though it is common belief that the San Pedro cactus aka Trichocereus pachanoi grows in Bolivia, all the San Pedro related plants we ever came across IN THE WILD either belonged to Trichocereus bridgesii or Trichocereus scopulicola. That also applies to the regional type from the Rio Mizque. I have all kinds of photos of those plants on the pages about Trichocereus riomizquensis and I don´t want to repeat this information here again.
This is a long-spined version of this but there also are a lot of short-spined ones on that site. I seen them. Just like this PC, they have 6-7 ribs, those weird areoles and golden spines without swollen spine bases. Overall, they are just a short-spined version of Trichocereus bridgesii.

Let me just say that one thing that the Bolivian Trichocereus species have in common is their drought resistance. They literally live in a hot desert and are a lot more resistant to drought than Trichocereus pachanoi or some of the other Peruvian San Pedros. And that´s where I want to draw the line directly to this Californian clone. Clones & cultivars are not humbug or bullshit….cultivars exist in EVERY field of commercial cultivation and everyone who tells you different is a fool. One such cultivar is actually this Tr. riomizquensis that was originally described by Friedrich Ritter. Is is extremely drought resistant and manages to thrive in the Californian climate. That´s why this plant is literally everywhere there. We tested it numerous times…almost none of those Californian plants were able to mate with each other…simply because they were genetically identical and cuttings of each other. I seen whole nurseries filled up with them because they are so damn easy to grow. They just cut them in small pieces and stick them into the ground. And after five years, they sell it for 30-100 bucks. All those plants share the same flower characteristics and are closer to Trichocereus bridgesii than they are to Trichocereus pachanoi. They are covered with white hairs, which is absolutely typical for Trichocereus bridgesii. I know a Bolivian Trichocereus species when I see one…and this PC is one without a doubt.

The flowers of the PC:

PC Flower_7

Do you see all those white hairs? Good, because it´s important to differentiate between certain Trichocereus species. Trichocereus pachanoi tends to have black or brown hairs, while this PC has white hairs. And that´s typical for the Bolivian San Pedro strains.

pcPachBudDSC_0462Those two photos are from Misplant.net! Check out their seeds because they are amazing.
Well, just compare the photos and see for yourself. The top photo is the flower bud of this PC Trichocereus and the lower one is a bud on a Trichocereus scopulicola. They are at different stages in their development, but I am sure you see the similarity in the important parts. And the same applies to the flower on Trichocereus bridgesii, which is another Bolivian Trichocereus.
Scopulicola5a

Scop from Misplant.net

Alright, now that we have this out of the way let me just say that the whole internet started having shitty discussions about the PC and what not. Most of the times, those guys just pick out one of the charasteristics of those plants and call  everything that resembles this Californian strain a PC…which is a really bad generalization. Imagine you were a botanist and field explorer that collected seeds in Bolivia. Now you find a cool regionality that produced a whole lot of seeds. Friedrich Ritter was this guy and collected so many seeds that he could populate the whole world with them…which he probably did. He sold his seeds through his Winter Samenlisten (which were written in three languages) and shipped them everywhere. Like literally. People grew them, raised those plants and planted them in their gardens. Some in California, some in Australia and some in other places of the world. That PC clone from California and the rest of the USA is probably just one cutting that was grown from those seeds. All the plants cloned from this one plant are genetically identical. But that doesn´t mean there can´t be more plants grown from the same seeds…which in fact are genetically diverse. You know, this whole site at the Rio Mizque is pretty big and as far as I know, Ritter collected loads of fruits. These days, most labels are lost but what´s left are the plants. And they are usually slapped with a short PC comment in the Facebook groups, though that is only a tiny piece of the puzzle.

And just to make sure this posting here is not misinterpreted. Are all the plants called PC the same? NO, absolutely not. Many people throw this word around and have absolutely no idea what they are talking about. Just one example. Here is a Bolivian San Pedro. As those are also related to Trichocereus bridgesii, they have a similar rib structure. Imagine them with long golden spines and you are good to go.

Trichocereus riomizquensis

Tr. aff pachanoi in Boliva

San Pedro in Boliva

Trichocereus aff. pachanoi in Boliva

Well, okay. I want to come to and end but it´s important to make a very good point. YES, there are many San Pedros that are extremely similar to this clone. Not all of them are the same and I am sure there´s a fair amount that has absolutely nothing to do with this PC. But there IS a common clone in the USA (apart from the many other cultivars that are there, such as the three or four types of cereus monstrosa or all the other mutants that are currently flooding ebay. Nurseries are in the money business and they will replicate everything they can sell. And those Bolivian Trichos (and I count that PC in as well) are TAH (Tough as hell). You literally stick them in the ground and they grow. And that played a part in the fact that this PC Trichocereus strain is so common in some parts of the USA.

Alright, I want to sum this up. Everyone is a bit in the right here. The way this plant is discussed recently is out of control. And some people tend to forget that there is a huge number of plants that are really similar to this PC…and they are coming from the habitats. In Peru, there are similar plants and I just posted the examples that you can find in Bolivia as well. But that doesn´t mean that those plants were just invented by cookoo internet theoreticians. They were collected, sold and commercially cultivated. This plant does probably NOT come from Backeberg, which is another theory that was discussed heavily.

Trichocereus macrogonus – Echinopsis macrogona

Trichocereus macrogonus – Echinopsis macrogona

Trichocereus macrogonus, also known as Echinopsis macrogona, is a columnar cactus.

The first description about it was made using the name Cereus macrogonus SD. Cact. Hort. Dyck.Cult.

Currently valid name name:

Echinopsis macrogona, the name is disputed by some authors and re-described as Trichocereus macrogonus by others. The whole genus Trichocereus is currently being revised and it´ll take a good 10 years till this is somewhat resolved. Echinopsis macrogona / Trichocereus macrogonus is at least partially synonymous with Echinopsis peruviana / Trichocereus peruvianus and it is difficult to clearly divide them. Both are contending names and due the older age of Trichocereus macrogonus (back then it was still called Cereus macrogonus, which was the name from the first description by Salm-Dyck), it´s possible that Trichocereus macrogonus / Echinopsis macrogona will replace Trichocereus peruvianus / Echinopsis peruviana as main species name for this group of plants.

T.macrogonus and its connection to Trichocereus peruvianus

Trichocereus macrogonus is an alternative name for some forms of Trichocereus peruvianus and many authors support this theory. These days, some Peruvian Trichocereus strains with brown spines and dark blue epidermis are usually sold as  Trichocereus macrogonus by seed sellers, but these plants are not really different enough to justify treating them as correct species.

Kiesling´s article on Cereus macrogonus

Kiesling wrote a very good piece on the species Trichocereus macrogonus and you can read it here:  http://www.cactusconservation.org/CCI/library/pdf/Albesiano_Kiesling_2012_Haseltonia_17_24-34.pdf

Trichocereus macrogonus is a very old name and since Britton and Rose came along with their description of Trichocereus peruvianus, the plants that used to be called Macrogonus were then treated as T. peruvianus. Due to the old age of the species name Trichocereus macrogonus, it is possible that it will be given priority over the newer name T. peruvianus IF the original description of T. macrogonus will be considered to be correct. Right now, this hasn’t been decided yet, but there’s a chance that this will happen.  However, many people want to keep the old name Trichocereus peruvianus just because it has a lot of history and traditions attached to it. The future of Trichocereus macrogonus is unclear and will be decided in the next years. Personally, I consider the name Trichocereus macrogonus to be extremely problematic due to the many problems associated with it, eg no type locality, no flower description, unclear origin, not being found again in nature, etc.

Synonyms of T. macrogonus:

Cereus macrogona, Echinopsis macrogona, Trichocereus macrogona, Trichocereus glaucus (sometimes. Trichocereus glaucus is a species related to T. chalaensis. However, many seed sellers offer certain strains from the T. peruvianus/macrogonus group as Trichocereus glaucus, eg KK336). Echinopsis glauca, Trichocereus glauca, many strains that belong to T. peruvianus.

Below you can find some photos of plants with this name from the commercial market. They differ greatly and not all belong to Trichocereus peruvianus. There are plants with the label Trichocereus macrogonus being sold that belong to T. bridgesii, T. pachanoi, T. peruvianus, T. werdermannianus, T. taquimbalensis, T. tacaquirensis, T. santaensis, T. bridgesii and Trichocereus cuzcoensis. Because of this, it makes no sense to use plants from the commercial market as standard for this species.

If you like this article, check out some of our other articles about the genus Trichocereus. Trichocereus peruvianus, Trichocereus bridgesii or Trichocereus pachanoi.

echinopsis macrogona trichocereus macrogonus Huntington Botanical Garden HBG 2Trichocereus macrogonus in the Huntington Botanical Garden by Richard Hipp

Origin of Trichocereus macrogonus:

Unkown. Possibly Bolivia but the species could never be found in Bolivia again. Originally, it was assumed that the plant came from Brasil and Borg wrote that the plant came from Bolivia or Argentinia but that could not be verified. Rauh found a Trichocereus in 1954 (collection number K68-1954) that may have been the wild Trichocereus macrogonus. That plant was found around the Mantaro Area in the middle of Peru.

This is the plant in question, and judging by its looks, it could actually be the originally described Trichocereus macrogonus. Back then, the plant was described as Cereus macrogonus (Salm-Dyk) and I know a very similar plant that was distributed by Karel Knize.

Trichocereus macrogonus Rauh and Backeberg Rio Tambo Echinopsis

And this pic is from Backeberg´s description and shows a plant that is very common in European collections!

trichocereus rauh Trichocereus macrogonus Echinopsis macrogona

Echinopsis macrogona or Trichocereus macrogonus is a columnar cactus that is very close to Trichocereus peruvianus or Echinopsis peruviana. Echinopsis macrogona is most likely synonymous with a certain, long-spined type of Peruvianus. The typical epidermis of  Trichocereus macrogonus has a frosty, blue color. Trichocereus macrogonus grows columnar and can get up to 3 meters tall and 3-5 centimeters in diameter. Some very large species can even reach a higher diameter. It has 6-9 radial thorns and 1-3 middle thorns that are up to 10 centimeters long.

Spines of Echinopsis macrogona:

The spines are dark brown, black or gray in color. New spine growth can also be yellow. The problem is that there are countless types that are called “Trichocereus Macrogonus”. Some definitely belong in the Trichocereus Cuzcoensis complex while some others are a very frosty type of Trichocereus Peruvianus from Matucana.

Areoles:

About 2 centimeters apart from each other and 5-10 mm in diameter. Brown-felted.

Flowers: White, near the  top and up to 18 centimeters long. Trichocereus Macrogonus is a night flowering species.

Fruit: Round fruit, shiny segmented fruit, black or dark brown in color.

Trichocereus Macrogonus is self sterile what means that you need two different species´to get seed.

Culture of Trichocereus macrogonus:

The culture of Trichocereus Macrogonus is very easy. Basically, it has exactly the same requirements as Trichocereus Pachanoi (San Pedro Cactus) or Trichocereus Peruvianus (Peruvian Torch). It is a very hardy plant that forgives a lot and as long as you treat it like a cactus instead of a swamp plant, it will pay you back with healthy growth every year. The cactus only needs water during the hot, growing seasons. That means that in summer, you can water it every week or even days as long you allow the soil to dry up between waterings.

You can improve the drainage o

Providing drainage

f your soil by adding purely mineral substrates like pumice, clay substrates like Seramis or simply sand. However, you should add a very small part commercial cactus soil because you want the substrate to be able to store nutrients and purely mineral substrates like sand tend to wash out nutrients very easily. Trichocereus Macrogonus likes a place with half-shade that gets a fair amount of sunlight every day. However, you should make sure not to burn the hell out of it. You need to adapt your plants slowly to sun light and if necessary you need to provide a shade cloth.

Winter & Frost: Trichocereus Macrogonus is a very hardy cactus that can take short night frosts down to -9° Celsius as long as the general health of the plant is ok. However, it requires a minimum average temperature of 10° celsius. That means it can take short frosts down to 15.8° Fahrenheit as maximum frost temperature. The average minimum temperature in Fahrenheit is 50° Fahrenheit.

Winter storage & Winter Protection:

Trichocereus Macrogonus likes a bright spot with lots of fresh air during the wintertime. If you have the luck to live in a country with very little frost, like Australia or the hotter parts of the USA, you wont have the problem of winter storage because you can grow your plants outside but most people in other parts of the world are not able do that.

Providing fresh air to tackle fungal problems

It´s best to store cacti in a very bright room with fresh air supply to prevent mold. The minimum temperature should be around 9° celsius/50° Fahrenheit. For this type of winter storage, the plants need to be kept dry, without any waterings in between October and April. If you have a greenhouse, you can start taking out the plants by May, but be careful about late night frosts because some south american species that take frost very well. For Trichocereus Macrogonus, this should not be a problem though.

Germination of Trichocereus macrogonus seeds:

The seeds of Trichocereus Macrogonus are like most other Echinopsis & Trichocereus seeds. They need light to germinate and should be sprinkled on top of the soil. They require a minimum germination temperature between 25° and 30° celsius and seedlings need to be watched carefully to prevent heat damage, because though temps up to 30° celsius increase germination rates, everything above can kill the young seedlings in an instant. Watch out for mold or fungus gnats. However, Trichocereus Macrogonus seedlings are actually tough.

Where to get seed: 

There are many seed suppliers that sell seed of Trichocereus macrogonus. However, be cautious because there one or two south american wholesalers that sell over aged seed. Please not that there are some extraordinarily good Seed distributors from South America so there is no general rule of thumb. That´s how life is and I would recommend you to test the seed you are offered before you buy a substantial amount of it. I have seen people tank hundreds of dollars for seed that produced one or two seedlings.

Seed Viability, Trichocereus macrogonus:

The seed is viable for many years. This is something that most Trichocereus have in common and the seed is probably viable for at least 5-10 years, though you get the best results within the first year.

Commercial strains, clones or field numbers associated with the name:

KK923 Trichocereus Macrogonus (Cieneguillas, Bolivia), KK1422 (Villa Abecia, Bolivia), KK2151 (Ayacucho, Peru), KK2175 Apurimac Pachachaca (Bolivia), KK2176 Ayacucho, Tr. macrogonus H1306 from the Huntington Botanical Garden, Trichocereus cv. Neon Palm, Trichocereus sp. Luther Burbank, Trichocereus SS01, Trichocereus cv. Oklahoma, and many more. List will be updated. If you know some more, let me know. But the fact that you could as well list all of those as Trichocereus Peruvianus makes this kinda pointless. Both types are synonymous and I just added this page because I dont want to leave it out.

Trichocereus macrogonus for sale

Trichocereus macrogonus is rarely available for sale. The species name is very old and the plants on the commercial market that you get with this label belong to all kinds of species. Most Trichocereus macrogonus for sale are Knize sourced Trichocereus werdermannianus, Trichocereus peruvianus, Trichocereus bridgesii etc.

Trichocereus macrogonus seeds

Like mentioned before, you can get Trichocereus macrogonus seeds from the commercial market. Since it is not known how the original Cereus macrogonus looked like, you can get all kinds of plants under this name. Trichocereus macrogonus and Trichocereus peruvianus are at least partially synonymous and sellers use both names interchangeably.

The Fields Macrogonus is an old Australian Trichocereus macrogonus clone that came to Australia through Blossfeld´s first South America expedition.

Trichocereus bridgesii (Echinopsis lageniformis)

Trichocereus bridgesii (Echinopsis lageniformis)

Trichocereus bridgesii (SD.) Britton & Rose – The Cactaceae, now called Echinopsis lageniformis because the name Echinopsis bridgesii was already taken.

C.F. Förster – H.Friedrich & GD Rowley 1974

CITES: Appendix II.

Origin of Trichocereus bridgesii:

Trichocereus bridgesii, also known as Echinopsis lageniformis, grows throughout Bolivia (LA PAZ, Chochabamba, Chuquisaca, Santa Cruz, Tarija. There are many close relatives, such as Trichocereus riomizquensis, Trichocereus crassicostatus, Trichocereus scopulicola and the populations from Isla Del Sol.

Synonyms of T. bridgesii:

Cereus lageniformis, cereus bridgesii, trichocereus crassicostatus, Cereus bridgesii var. longispinus, Cereus bridgesii brevispinus, Cereus lasiacanthus, Trichocereus boliviensis, Trichocereus riomizquensis (some of them),  and many more.

Some of the Varieties or commercial types on the market:

KK919 Trichocereus bridgesii, KK920 Trichocereus bridgesii, Trichocereus bridgesii Cristata, TBM type A, TBM type B, Lumberjack, Eileen, Jeans, Psycho0, TBM,  Penis Plant, Penis Cactus, Frauenglück or Frauenglueck, Trichocereus bridgesii var. Inermis, Eileen,and many more

Trichocereus bridgesii has been renamed to Echinopsis lageniformis by Friedrich and Rowley during their 1974 merger of the genus Echinopsis. The name Echinopsis bridgesii was already taken by a clumping Echinopsis species from Bolivia, which is a totally different plant and should not be confused with Trichocereus bridgesii.

Trichocereus bridgesii is also called the Bolivian Torch or Achuma and is a very fast growing columnar cactus from the high deserts of Bolivia. It its extremely drought tolerant and withstands colder temperatures than some other Trichocereus species. If you are new to cacti but want to grow one of the San Pedro type cacti, Trichocereus bridgesii is a perfect plant for you.

Description of T.bridgesii

Healthy plants of Echinopsis lageniformis  Trichocereus bridgesii have a light green epidermis and between four to eight ribs. The spines can range in coloration from honey-colored to brown, and are located at the nodes in groups of up to four.

It grows similar to a tree and reaches a size of up to 5 meters. The Species is not as glaucous as Trichocereus peruvianus and Trichocereus pachanoi and has a light green epidermis.

Trichocereus bridgesii reaches up to 15 centimeters in diameter and large specimens are often confused with Trichocereus peruvianus. The fact that very thick specimens can look a lot like Trichocereus peruvianus is a reason that there are many misidentified specimens on the market. Some sellers even label them “SAN PEDRO”, “PERUVIAN TORCH” or simply Trichocereus peruvianus / Trichocereus pachanoi, because they usually are more expensive as Trichocereus bridgesii.

It has 4-8 Ribs and the Areoles are about 2 centimeters distanced of each other. Four-ribbed plants are sometimes called “Trichocereus of the four Winds”, though it´s actually a lot more common for this species to grow or lose a rib than you would think. Besides, that four winds stuff is oftenly used as a marketing gimmick, though the plants grow and lose ribs all the time.
A Trichocereus that grows a rib looks very much like it would put out some monstrose growth, but on the long term you see that it´s just ribs.

But yeah, the larger they get the more ribs they can have. Trichocereus bridgesii has very broad furrows. The plant can reach up to 3-5 meters.

Spines of Echinopsis lageniformis / T.bridgesii:

4-6 needle-like, yellow Spines. Some of them are very uneven and vary greatly in length and appearance. Some large plants even lose their spines completely. This is something that we encountered a couple of times on larger plants and spineless Bridgesii´s look very much large hybrids between Trichocereus peruvianus and Trichocereus bridgesii.

Flower of Tr.bridgesii :

The flowers of Trichocereus bridgesii are white and up to 20 centimeters long and 10 centimeters in diameter. Trichocereus bridgesii is a night flowering species and its fruits are usually up to 5 centimeters long. It had white petals and small scales and hairs on the rest of the flower.

Type locality:

Bolivia, La Paz

Trichocereus bridgesii as Grafting Stock:

Trichocereus bridgesii is an excellent grafting stock and is used extensively for that. Though it´s a great stock, it´s not as accepting as Trichocereus spachianus or a cereus. Nonetheless, it´s a strong and vigorously growing stock that will produce large scions very fast.

Regional forms of T. bridgesii:

The fact that most regional forms look very similar makes it very hard to differentiate between them. There are many known clones available, but Trichocereus bridgesii isnt just as variable as the Peruvian species.

The monstrose form of Echinopsis lageniformis/Trichocereus bridgesii is called PENIS PLANT or TBM, sometimes also called Trichocereus bridgesii Inermis. Contrary to the typical columnar growth habit of the species, the TBM cultivar displays short stem segments that branch forming a small bush. The upper part of each stem section is smooth and spineless, resembling a certain male body part. The lower part shows a tendency to form ribs and is spiny. The plant is light green in color.

Cultivation of Trichocereus bridgesii

This species is one of the strongest growers in the genus Trichocereus or Echinopsis. It´s VERY drought resistant and less problematic than other Trichos. Especially if you grow them from seed, because no matter what else you grow, they will be the ones to survive the longest if you suddenly “forget” to water them for a month or so. The come from Bolivia and live off very little water but also manage to compensate strong rainfalls and are rarely affected by fungal infections or mold. It´s a very thankful plant to grow, especially when you have the luck to plant them outside.

So, cultivation is pretty easy. Don´t water them when it´s cold. It´s the same treatment that you would give any other Trichocereus. Only water them during the hot growth season in summer. If they are in full growth and the temperatures are high, they like to be watered on a weekly basis, but it depends on how fast the soil dries up.

Hold back the humus

They don´t like soils that contains too much humus and i´d recommend to grow them in a purely mineral soil mix, with pumice, coarse river sand and maybe a very little bit of standard cactus soil to make sure that they are able to take in the nutrients. Generally speaking, Trichocereus bridgesii is the  archetype of a cactus that thrives on poor soils. I would not recommend to put them in full sun for the whole day but they can take much more sun that other Trichos that come from more tropical climates.

Winter treatment & frost tolerance:

Trichocereus bridgesii is able to tolerate mild frost. The minimum temperature should now go below -5° Celsius though.  Trichocereus bridgesii usually has no problems to compensate light night frosts but the average minimum temperature should not be lower than 10° Celsius! That is around 50° Fahrenheit. One important factor in frost resistance is the humidity of a soil! Plants should be totally dry in winter to make it easier for them to deal with frost. That´s why growers in Europe and other countries with strong frost have to take em inside in winter. The moisture is more dangerous than the cold, though there is a temperature that will kill all cacti no matter how dry they are. Cacti require a bright and well ventilated space with a temperature around 10° Celsius. Not only ensure it that the plants soil system does not rot, it also promotes flowering!

Cultivation from seed:

Trichocereus bridgesii is very easy to grow from seed. The seeds remain their viability for 5-10 years and some even longer. The best germination rate can be expected within the first year though. The seeds require light to germinate and you only sprinkle them on top of the soil. As a germination medium, I would recommend a mix between sowing soil and coarse sharp sand. This reduces your chance of contamination and/or Algae/Moss production.

Moss and algae problems on Trichocereus

Moss and Algae are a real problem for cactus growers because they overgrow your seedlings and usually kill them. If you see green crap on your soil, that is exactly what I am talking about. The seeds only need very little water to germinate, so do not overwater them in the beginning. You can always add more water but you can never take back a bad overwatering because it usually washes the seeds away or will lead to rotten seeds and soil.

Germination temperature for E.lageniformis

Germination temperature for Trichocereus bridgesii or Echinopsis lageniformis is around 25°-30° Celsius. But be careful because small seedlings die very easily because of too much heat. Especially if you germinate in closed containers, temps can get quite high in there. The time needed for them to germinate is between 2-6 weeks. If nothing has germinated after that, it´s probably because a.) there wasn’t enough water to kick start the germination. In this case just add more water and wait some more. b.) the temperatures were not high enough. In this case, just increase the temps and continue to germinate. Or C.) The seed is dead.

Bad quality Trichocereus seeds

There are a couple black sheep in seed business who sell seed that´s between 10-20 years old and the viability is horrible. So if you did everything right and nothing germinated, it´s the seed. Seed quality on the market varies greatly and you never know what batch you will end up with. So if you had a batch batch, I´d recommend you to contact the seller and ask him about it. Stay friendly and polite and they will replace it because they are aware of the great differences in seed quality.

Propagation: 

Trichocereus bridgesii can be grown from seed pretty easily. But you can also take cuttings and re-root them. This way, you can multiply your plants dramatically and if you are trying to get a lot of plants, you can also try areole grafting. Trichocereus bridgesii is pretty tough and you can basically stick it in a dry medium like sand and it will probably grow. Just make sure to let the cuts dry out and give the wound enough fresh air until everything is calloused. I use bird sand for that purpose, which is the mineral soil mix that you get in pet stores for the birds to take their dump in. It contains anise and some other minerals that just prevent mold and infections and it is perfect for rooting plants in it.

USDA Zones Trichocereus bridgesii: 

10a, 10B and 11

Purposes: 

Can be used as grafting stock or just because its´an amazing cactus. Besides, Trichocereus bridgesii is used as natural fence to keep away animals and people.
