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 arboricola Video

Trichocereus arboricola has a lot of potential for hybrid breeding. The flowers are very beautiful and look similar to the flowers of Trichocereus thelegonus. Trichocereus arboricola is a rare Bolivian Trichocereus species that isn´t widely available, but in the last years it has gotten a lot more available. I crossed Trichocereus arboricola with Trichocereus shaferi, and there are various top notch crosses available from Misplant and other breeders.

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 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 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.

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 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 / 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 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 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 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 bridgesii (Echinopsis lageniformis) Mega Page

Introduction

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.

 

Commercial varieties 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.

 

Flowers 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 with the organics

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.

Trichocereus cephalomacrostibas / Echinopsis cephalomcacrostibas Weberbauerocereus

Trichocereus cephalomacrostibas / Echinopsis cephalomcacrostibas Weberbauerocereus

Trichocereus cephalomcarostibas, also known as Echinopsis cephalomacrostibas, is a columnar cactus that was described as a Trichocereus species by Curt Backeberg and Werner Rauh. However, the plant in question later turned out as a Weberbauerocereus and the flower makes it pretty obvious that Echinopsis cephalomacrostibas is not a Trichocereus.

The currently valid name of this species is Echinopsis cephalomacrostibas, but most authors went on to treat it as an incorrect species or move it to Weberbauerocereus as Weberbauerocereus cephalomacrostibas.

The original description of Trichocereus cephalomacrostibas

The original description was published by Backeberg and Werdermann in the book NEUE KAKTEEN, which is German for NEW CACTI. The book was released in 1931. The original description described a plant that was then called cereus cephalomacrostibas. Most plants that are now part of the genus Trichocereus were treated as Cereus at the time, which is why the name wasn’t surprising.

Trichocereus cephalomacrostibas, also known as Echinopsis cephalomacrostibas, gets 1,5 – 2 meters tall and pups have a maximum diameter of 8-12 centimeters. The areoles are very close to each other, which is even more obvious on older plants later on. The areoles are between 1-2 centimeters in diameter and the plant is very spiny. It has up to 20 small radial spines and between 1-3 middle spines that can be up to 14 centimeters long. The spines are dark brown to red brown (old growth gray). It´s noteworthy that the original flower from the Backeberg description only had a size of 12 cm (which would fit here), but was said to have scales on the flower. Besides, it was supposed to be white instead of this cream or beige color.

Origin: South peru, near Mollendo.

Please note that there also is a plant called KK1421 Trichocereus cephalomacrostibas that has nothing to do with this plant anmd, that probably grew on the same site  and was confused with a Trichocereus.

KK1421 Trichocereus cephalomacrostibas cv. Rio Tambo

This field collected Trichocereus cephalomacrostibas / Echinopsis cephalomacrostibas is fairly interesting though it probably has nothing in common with the species that it is supposed to be part of. Knize collected this nice strain near the Rio Tambo in Peru. It almost looks like a spiny Trichocereus pachanoi strain and should definitely be investigated some more.

If you compare those two plants to the plant that was originally described as Trichocereus cephalomacrostibas, it gets obvious that they are all different plants. The plant in the link was actually a Weberbauerocereus. The seed and the flower are so unlike the ones on any other Trichocereus that it´s absolutely obvious that it’s not a Trichocereus.  But that’s a different story. The original Trichocereus cephalomacrostibas (you know, the one from the link, which actually is a Weberbauerocereus) is said to grow east of Mollendo in the Department Arequipa and occurs from Chala to the Rio Tambo in the south. And that’s where KK1421 is said to originate from. Rio Tambo.

Case of mistaken identity ?

Just because there are Trichos near the Rio Tambo, it does not make em automatically the same population of this Trichocereus cephalomacrostibas from the description. That´s not Ill will but just the flaws of this particular labeling system. It´s  just natural that you can sometimes find a couple of different plants growing at the same area. And because of that, seed collectors should give every single collection (instead of just the whole collection site) a unique number, so you can easier track them down and see which ones would fit in the descriptions and which ones don´t.

Alright, what does that say about those two different plants labeled as KK1421. Well, very little. Both are interesting Trichocereus and while one of them is definitely a cuzcoensis relative, the other one needs further investigation.

Another KK1421 Trichocereus cephalomacrostibas

The original description goes like this:

Cereus cephalomacrostibas grows in packed groups of columnar cacti that get up to 2 meters tall. They are up to 10 cm thick, a gray-green color, tightly packed areoles, 3 – 6 radial spines and 3 middle spines. The flower is 12 cm long (which is too small for a Trichocereus flower), white, covered with white wool and scales. This original plant occurs in South Peru, above Mollendo.

Now back to KK1421: The Seeds came from Karel Knize and were originally collected from Matarani, Peru at 300m altitude. Knize´s plant obviously comes from the group around Tr. cuzcoensis but it´s difficult to know if this is actually the same plant as Backeberg described as I lack a pic of the flower. What I can say is that 12 cm would be very small of a Trichocereus flower. And there are pics showing a type of Weberbauerocereus, which most believe is THE original Tr. cephalomacrostibas. Mr. Knize´s plant is 100% sure NOT a weberbauerocereus.

Where to buy seeds of KK1421: I actually have some in my shop every now and then. Check it out here: trichocereus.net/shop . This article is an excerpt from my book KAREL KNIZE TRICHOCEREUS FIELD GUIDE.

Trichocereus chalaensis (Rauh & Backeberg) Echinopsis

Trichocereus chalaensis (Rauh & Backeberg) Echinopsis

Trichocereus chalaensis is a Peruvian Trichocereus species that is closely related to Trichocereus glaucus. Its alternative Echinopsis name is Echinopsis chalaensis (Rauh & Backeberg). I treat it as a correct species in the genus Trichocereus until DNA testing is able to disprove this. Right now, the name Echinopsis chalaensis is still formally valid, but it´s just a matter of time until the new findings and decisions on the taxonomy of these former Echinopsis Trichos will lead to the official revival of the genus Trichocereus and some of its former species. I follow Joel Lodé´s system, which lists the plant as Trichocereus chalaensis (Rauh & Backeberg).

The type locality & origin: Peru, Arequipa. Chala in the south of Peru. This species was  collected by various field botanists, including Friedrich Ritter & Rauh. Rauh´s collection number is “Rauh K128” and Friedrich Ritters FR number is FR1052. The type is common in the southern parts of Peru and usually grows creeping down slopes, similar to Trichocereus glaucus var. pendens. Because of that, it´s possible they are at least partially synonymous.

Synonyms of Echinopsis chalaensis:

Trichocereus chalaensis, Echinopsis chalaensis, SS04, Trichocereus glaucus, Trichocereus glaucus var. pendens, Trichocereus lucernatus,

Sacred Succulents sold this species under a couple of different names. Trichocereus glaucus, of which there are pics of on Michael Smith´s amazing Flickr Page! Besides, they sold/sell this type as SS04 and Trichocereus chalaensis.

he description is very similar to the one of Trichocereus glaucus (Ritter) and it´s definitely possible that this is the same plant.

Description of Trichocereus chalaensis:

Trichocereus chalaensis grows like a shrub and can often be found growing prostate on rocky slopes or little hills. It can get between 3-5 meters tall and reaches a maximum diameter of up to 18 centimeters. It has 7-9 ribs and has very strong furrows. The spines are dark brown to red and extremely beautiful. The color is similar to the spines on the Trichocereus fulvilanus form of Trichocereus deserticolus / Echinopsis deserticola.

Trichocereus chalaensis has 1-3 middle spines (3-6 centimeters) and 5-11 radial spines (1-2 centimeters), depending on the region. The spines reach a maximum length of 5-7 centimeters. The plant has very strong furrows, directly above the areoles.

Flowers of E. chalaensis:

The flowers are white and look similar to the ones on Trichocereus glaucus. Trichocereus chalaensis is a night flowering species and it is self-sterile. That means that you need another plant to act as a pollen donor in order to produce seeds. Some flowers I saw were up to 20 centimeters large and up to 12 centimeters wide. But flower size differentiated greatly and the norm was around 14 centimeters. Very beautiful and well scented flowers though. Tube is about 2,5 centimeters thick, with dark brown and black hairs, sepals reddish to green in color and the petals are white.

Trichocereus chalaensis usually has a bright green color. The species is very close to Trichocereus glaucus and Friedrich Ritter considered it as a distant relative of Trichocereus chiloensis. He thought that the complex around T. glaucus/chalaensis originated from Chile and made their way by invasive evolution through large parts of south Peru. Trichocereus chalaensis is the most northern growing Trichocereus species, reaching from the southern part of the Chilean cactus west to the north all around the coast and in some parts west of the desert-belt, while all other Trichocereus were growing in the east, in much higher regions. Trichocereus chalaensis grows at around 200 meters altitude, which is really low for a Trichocereus.

 Cultivation of T. chalaensis:

There is not really that much information about how to grow this plant and about its frost resistance. I know of growers that grow Trichocereus chalaensis in California indicates that it is probably similar as other Trichocereus, what would mean that it might stand short night frosts and requires a minimum average temperature of 10° Celsius. I planted some of them too this year, but they are still too small to say more or make pictures of them. I will post more pics of Trichocereus chalaensis in the next couple days.

Sources for Trichocereus chalaensis seeds: 

This plant is really rare in cultivation, but there are a couple of shops and sellers that sell seed every now and then. Sacred Succulents is selling them as SS04 and as Trichocereus chalaensis but that´s about the only source I know apart from the cuttings that are actively traded in our Trichocereus Facebook group at https://facebook.com/groups/trichocereus. Most recently, Misplant has stocked some rare Trichocereus chalaensis hybrids as well.

Trichocereus harrissima (nomen nudum)

Trichocereus harrissima (nomen nudum)

Alright, it´s obvious that Trichocereus harrissima is not an accepted species. The name probably came from a seed or plant seller who sold this plant at some point in the past. I list it as a nomen nudum here, which means that it is a bad name that it is a “nude name” that lacks a formal description. This plant is actually Trichocereus purpureopilosus, which was described under that name and is extensively used in hybrid culture.

Trichocereus purpureopilosus is an amazing cactus with a beautiful appearance and flowers. The flowers are white in color and you can find out more about it here on the page: I wrote a whole lot more about this species on the page about it.

Synonyms: Trichocereus brevispinulosus, Trichocereus purpureopilosus.

I am currently not sure where the name Trichocereus Harrissima came from but I know for a fact that it originated after it was sold under that name. The name could be a reference to the genus Harissia, but it is very different to most plants from that genus.
