Trichocereus Lookalikes

There are various columnar cacti that you can encounter. And though many look very much like Trichocereus on the first look, many of them actually aren’t. This page is about the many lookalikes that are available on the open market. Some of them are labeled “Trichocereus” and some of them aren’t. It includes many plants that were originally collected by seed collectors and field botanists who made a description without having seen the flowers. Because despite the fact that many columnar cacti can be very similar to Trichocereus in their looks, the flowers are what´s usually the biggest help to find out more about the origin of a plant.

Soehrensia (Echinopsis formosa, Echinopsis bruchii)

Soehrensias are very similar to Trichocereus. However, most of them stay small, have way too many ribs or a different flower. In addition to that, some of them (like Soehrensia formosa) are very broad and thick. Soehrensias were integrated into the genus Echinopsis, until DNA testing revealed that they are very different in regards to their genetic profile. Because of that, they are regarded a real genus again.


This genus is not really a genus anymore and those plants were moved into the genus Browningia. The current name of the species shown is Browningia chlorocarpa. Other former Gymnanthocerei are now called Browningia altissima (Gymnanthocereus altissimus), Browningia Pilleifera (Gymnanthocereus pilleifer). There always was taxonomic chaos surrounding those plants and very few pictures exist. The flowers are usually a lot smaller than the ones on Trichocereus and vary in many more aspects.

Origin: Huancabamba and Abra Porculla. Ritters collection Number was FR 290. This species was also called Seticereus Chlorocarpus. If you have pics of any former Gymnanthocereus species, please let me know because I´d love to have more Trichocereus Lookalikes on the site.



This genus is extremely interesting and I am constantly looking for new pics or seeds of Rauhocereus species. The most popular one is Rauhocereus Riosanijiensis. There are´t many sources where you can buy seeds or plants. The breeder misplant sold a couple seedgrown Rauhocereus last year but I am not sure if he will get some more.

KK340 Trichocereus cuzcoensis (Echinopsis)

KK340 Trichocereus cuzcoensis (Echinopsis)

KK340 Trichocereus cuzcoensis is a wild strain collected by Karel Knize. Knize´s numbers stand for regions instead of mother plants, which is why there are various different plants with this field number and not all are the same species. Most ended up to be Trichocereus cuzcoensis, but the photos show that at least some of them are Trichocereus peruvianus or close to it.  The first strain was on the 1998 seed list and Karel gave “Area Cuzco” as place of origin. It also turned up on his 1999 seed list as var. cuzcoensis. In the year 2000, Knize sold it through his cuttings list. He also sold it as seed and cuttings through his 2004 Seed list with the remarks “Cuzco, Huachac, 3200 meters”.

I lack more pics of this plant to say anything for certain. The pics of the relatively small cuttings that Knize sent look like a mix between Trichocereus Cuzcoensis and Trichocereus Peruvianus. There is no real source for seeds or plants, apart from maybe Karel Knize. But everytime I tried buying from him, he let me down and either sent me nothing or dead seed. I always wanted to do business with him but ended up being extremely disappointed and frustrated. Well, but enough of that.

This pic shows KK340 Trichocereus cuzcoensis and is from the Shaman Australis shop. It shows a rather typical Cuzcoensis with a bright green epidermis. The plant is currently out of stock but if you are interested to buy one, maybe send them a message and ask if they will get them again.

We are working on a Karel Knize Field Guide or database, but I do not know when it´ll be finished. If you have photos of KK plants, please send them over and we´ll include them.

KK336 Trichocereus glaucus – Echinopsis glauca

I am totally not sure if Knize´s Trichocereus glaucus is actually the same plant that Friedrich Ritter described as Trichocereus glaucus. Here is what I have about Knize´s KK336. He sold the plant for a very long time and collected them at various sites. The first one was sold through Knize 1999 seed list and is supposedly from Rio Tambo at around 1500 meters. The plants look totally different to what Ritter described so I am not sure how Knize got the idea that KK336 is actually a Glaucus. I assume it was only based on the glaucous epidermis, which is really very blue. He also sold it through the 2004 seed list using the remark “Rio Tambo, Arequipa, Peru”.

I am sure that there are many of those KK336 on the open market but most of them are probably labeled as Trichocereus peruvianus, Macrogonus or Pachanoi. All plants that I ever came across with the label Trichocereus glaucus were more or less glaucous Perus.

The KK336 is definitely one of the coolest San Pedros that I´ve ever seen and it reminds me a lot of the dark blue Peruvianus from Matucana.

Where to buy seeds or plants of KK336: There sometimes are some american shops that sell this type on ebay. It´s been a while since I last saw one but they are definitely out there. Either as Trichocereus Glaucus, Macrogonus or Peruvianus. Knize also sold it as seed and live cuttings but I wrote about the shipping problems with him before.

Trichocereus schickendantzii (Echinopsis schickendantzii)

Trichocereus schickendantzii (Echinopsis) was originally described by Britton & Rose in their book THE CACTACEAE, which was published in 1920. The plants grow in large clusters, in which they are pupping abundantly from the base! They can get up to 40-50 Centimeters, though they usually stay around 30. They have a diameter of 5-8 centimeters and a very healthy, green colored epidermis.

Ribs: They usually have between 13-18 ribs that are between 0,5 and 1 cm high. The spines are yellow and between 1-2 cm long. It has 7-10 radial spines and 2-7 middle spines.

Flowers of Trichocereus schickendantzii:

The flowers are white and can get between 20-25 centimeters long with green tube and sepals and black heairs/white petals

Origin: Argentina, Tucuman

Cultivation: Trichocereus Schickendantzii is a very popular grafting stock and a hardy cactus. They can take a lot of water during the hot season, but should not get wet “feet”. The average temperature should be around 10° celsius during the winter time. In summer, they can be grown in full sun but usually prefer a spot with partial shade. They should be hardy down to at least 0° celsius (and maybe even more) but I would not feel comfortable testing the boundaries. In a European country like Germany or France, they won´t survive the winter if kept outside. Some growers in the south of france reported that they tried to overwinter it with some rain protection but I am not sure if it worked. They should be totally dry during the winter and only be watered from April to Oktober.

Seeds of Echinopsis schickendantzii

There are a couple of growers who offer seed every now and then on our Trichocereus Group on Facebook. The plant is also sometimes in stock in the SAB Shop. Apart from that, you might also be lucky to get it from Seed suppliers like Köhres or Kakteen Haage but I have no idea how viable their seed is. In case of fresh seed, they are very easy to grow from seed. They prefer a mineralic soil type.

At a very young age, they look very much like Trichocereus Grandiflorus. However, they don´t get as big as Grandiflorus and have a different pupping behaviour. But generally speaking, they can be very similar and many pics labeled as Schickendantzii, including some on that page may or may not belong to Trichocereus Grandiflorus. The pic that is underlined with cs California shows a very typical Schickendantzii, which is substantially smaller than the ones on the other pics. But since there also are hybrids, it´s pretty tough to keep them seperate from the more columnar growing Grandifloras.

Thank you very much to everyone who donated the Pictures! I greatly appreciate it!

Terscheckiinot (Peruvianus/Cuzcoensis)

Terscheckiinot (Peruvianus/Cuzcoensis)

This plant is from the breeder Shruman and I lack any substantial Information on the plant. I once got seed but unfortunately, the viability was not great so I did not get any adult plants from it. I would love to know more about it but currently, this pic is the only one I have and if anyone has this clone, please let me know and I´ll add some more pics or a description.

On the first look, I am inclinded to think that it is actually a Trichocereus Werdermannianus, which is most likely related to Trichocereus Taquimbalensis. The more I look at it, the more I think that this plant definitely shares some characteristics with Trichocereus Werdermannianus, such as the pale blue epidermis and the spination. If I see this correctly, its spines have a knobby base and a light touch of red, which would make it even more likely that it´s a Werdermannianus.
Nonetheless, I will keep it as Trichocereus cv. Terscheckiinot because thats the name it was given from Shruman. And I agree it definitely isnt a Trichocereus Terscheckii.

Buy seeds or plants: Just like I mentioned before, the only known source for this plant is Shruman. He sold or traded away seed of it but that was at least 2-3 years ago. Nonetheless, if you are interested in this type, you can make a post in the Trichocereus Facebook Group and maybe someone can help you.  The pic came from Prier and I´ll ask him if he knows more about it.

Trichocereus crassiarboreus (NN)

Trichocereus crassiarboreus is a plant that was discovered by Friedrich Ritter in 1957. When he found flowering specimens in 1964, he moved the species to Weberbauerocereus. I am not a specialist on Weberbauerocereus but I trust Ritters Experience on that ID. The species was later published by Karel Knize under the name Weberbauerocereus crassiarboreus but his description lacked substantial information and like the type locality, which made it impossible to have a baseline to compare against.

Karel Knize provided no photos for his collection, what makes it even more problematic to trace it back. Ritter wrote numerous interesting articles about this plant, including a complete description. Nonetheless, it seems that Knize´s description was the one that had priority. Because of that, Trichocereus crassiaboreus is now called Weberbauerocereus cuzcoensis. That also explains why Trichocereus crassiarboreus is nowhere to be found on most commercial seed and plant lists. At least not under this name. I have seen Weberbauerocereus cuzcoensis and it is a gorgeous plant that looks remarkably like a Trichocereus. I have never seen the flower of this species though. I also grew seeds from Karel Knize´s collection and they look a lot like Trichocereus glaucus so far.

Buy seed or plants of Trichocereus crassiarboreus:

The seed seller köhres once had some seeds of Trichocereus crassiarboreus/Weberbauerocereus cuzcoensis in stock. They are amazing plants and everyone should consider himself lucky to grow them. I might also add a flower description and a general description of this plant in the near future. But because it is not a real Trichocereus, I will push that back until I am done with the rest of the site!

Trichocereus poco (Echinopsis tarijensis)

Trichocereus poco (Echinopsis tarijensis ssp. tarijensis)

Synonyms: Trichocereus poco, Echinopsis poco, Helianthocereus poco, Trichocereus tarijensis var. poco, Trichocereus narvaecensis, Trichocereus poco var. fricianus, Trichocereus totorillanus

Taxonomic Background: These days, Trichocereus poco has been moved into the species Echinopsis tarijensis, formerly known as Trichocereus tarijensis. There are minor differences between these two, but that´s a normal thing within the genus Trichocereus. Trichocereus tarijensis is extremely variable and minor differences in appearance are to be expected. Backeberg tried to keep it separate from Trichocereus tarijensis (because he has a history of describing many species that were not really needed) and used the name “Helianthocereus poco” for the tarijensis-type Trichos from the southern highlands of Bolivia. His description was very lacking, in particular about the traits of the adult plants in the habitat.

Description: Trichocereus poco aka Echinopsis tarijensis var. poco grows like a tree and has between 16-20 needle-like spines per areole in his juvenile form. The adult form has 30-50 stump bristle-spines that are usually bent and twisted. Trichocereus poco starts shapeshifting into its adult form around a size of 50-70 centimeters while Trichocereus tarijensis has to get a little higher (1-2 meters) to start looking as its adult form.

Ribs: 20-32.

Flower: A mix between orange and red. 10-15 centimeters long, white with a little touch of rose on top, stylus white to red, filaments bright green (lower part) to white (upper part). There also are variations of the flower in colors like white, pink, beige, peach, etc.

Origin: Trichocereus poco grows in Bolivia and Argentina.

Cultivation: Trichocereus poco should not receive too much water and requires a good drainage to stay healthy. Species with such a thick spination should be kept drier than other species. The temperatures should never get lower than -5° celsius, though it probably tolerates short time night frosts of down to -9° celsius. But that is really not something that you would want to try because it already starts getting rot problems at around 0° celsius. So keep it dry, overwinter it at a bright and well ventilated area with temperatures around 10° celsius/50° Fahrenheit. If you live in a country with very mild winters, you might be able to get it over the winter by giving it additional frost protection, like a roofing and a purely mineral soil.

Seed & live cuttings sources: There are really not many sources for some seed of Trichocereus poco and most I know came from Köhres. There also are some live specimens on sites like eBay or Amazon sometimes and they make an amazing showroom plant.

Germination: They should be treated like seeds of Trichocereus Tarijensis or Trichocereus Terscheckii. Temperatures between 25° -29° celsius will be sufficient to make the magic happening. Make sure to give it a cactus soil that dries out very fast and only water every now and then after the old water has drained up. Light helps to induce the germination process, so maybe try adding a LED or HPS lamp to your sowing setup and you will get higher germination rates.

Trichocereus pasacana – Echinopsis atacamensis ssp.pasacana

Trichocereus pascana, also known as Echinopsis atacamensis ssp.pasacana, is a columnar cactus that can be found growing throughout the Andes.

Synonyms of Trichocereus pasacana:

Helianthocereus pasacana, Cereus pasacana, Pilosocereus pasacana, Echinopsis atacamensis, Echinopsis rivierii, , Echinopsis formosima, Trichocereus atacamensis ssp.pasacana, Echinopsis pasacana


Trichocereus pasacana is a tree-like cactus that gets up to 10 meters tall though the average height is usually a lot less. It can reach a diameter of 30-45 centimeters and has between 18-22 ribs. It has a lot of small, needle-like spines that can get up to 10-15 centimeters in length. The mature form looks a lot different to its early appearance. The spines are yellow in color and their length is decreasing during the life cycle of the plant. Old plants tend to have lesser spines that young ones and the early spine form is a lot stronger that the adult form.


The flower is white. 10-15 centimeters long. The flower has hairs on most parts and covered with a dark brown wool.


Round, up to 3 centimeters large.


Argentina, Catamarca, Jujuy, Tucuman, Salta and some parts of Bolivia.

There are different varieties of this plant and some tend to branch more than the others that grow like trees. The overall appearance of this plant is extremely variable and there are many intermediate tips between Trichocereus Pasacana, Trichocereus Terscheckii and Trichocereus Atacamensis. Because of that, most descriptions only cover certain varieties of this plant.

Close genetic proximity to other species

Trichocereus Pasacana is 0ne of those plants that are making it hard to draw the line. Backeberg considered this plant to belong into his own described Genus “HELIANTHOCEREUS” which divided the Day flowering from the Night flowering Plants but that was not accepted and reversed very soon after. The new taxonomic name of Trichocereus Pasacana is Echinopsis Atacamensis ssp. Pasacana, though I think Hunt decided to re-position the whole thing in Trichocereus. No matter what, it´s a remarkable plant that is extremely impressive. And the differences between Trichocereus Pasacana and Trichocereus Atacamensis are so minor that it is very likely that Pasacana is just a Variety of Trichocereus Atacamensis, which has priority. The difference between both types is that Trichocereus Pasacana tends to grow branched, while Trichocereus Atacamensis grows more like a tree. Trichocereus Pasacana is also called Cardon Grande, because of its large and mindblowing appearance!


Trichocereus Pasacana is a slow growing Tricho that should not be watered too much. It likes a little water every now and then in summer, but only when it´s actively growing. They should not be watered when it´s cold or rainy. Trichocereus Pasacana makes an extremely beautiful gardne plant but can get really big, so it´s actually only probable to grow them in a greenhouse that is heated all year long or in countries where they can grow outside. They usually produce very large root balls and if you grow them in a pot, it will get really heavy very soon.

Frost Tolerance Trichocereus pasacana:

The most important factor that influences frost tolerance is the wetness of the soil. Trichocereus Pasacana can tolerate very low temperatures for short periods of time. -5° celsius should be the limit though because low temperatures can cause the plant to rot. The minimum average temperature is around 10° celsius/50° Fahrenheit. It may even be possible for them to survive short night frosts lower than -5° celsius but I would absolutely not recommend it because it can leave permanent damage that doesn´t immediately show. But again, the plants HAVE to be dry over winter, no matter what. Personally, I don’t grow those Trichos in Europe because they just tend to get so massive that its hard to carry the pot.

Growing Trichocereus pasacana from seed: 

Trichocereus Pasacana is very easy from seed and requires the same treatment as Trichocereus Terscheckii. It helps to allow the seeds to cool down during the night to increase germination rates. But the minimum temperature required to germinate them is between 25° and 29° celsius. The seedlings don’t need that much water and can germinate with very little. The nutrients stored in the seed corn will allow the seedlings to grow a couple of months without fertilizer. But after then, you should fertilize them with a very weak fertilizer solution. VERY WEAK is the important word, or they might die because of fertilizer burns, which looks similar to sunburn.

Live plant & seed sources:

Most seeds on the market have a crappy quality and there are very little professionals who sell this type of seed. The fact that those plants have to reach a very large size before they flower leads to very little growers giving away some seeds. But every now and then, private growers in our Trichocereus Group give away some seed. Apart from that, you can get live cuttings on various places, including Ebay, Amazon and online nurseries. Often times, cuttings sold as Trichocereus Pasacana are actually Trichocereus Terscheckii, which is caused by their similarity at a young age. There are very little differences you can keep them apart.

Trichocereus pasacana for sale

Trichocereus pasacana is rarely for sale, but you can sometimes get lucky by obtaining a cutting from fellow growers who cut back their gigantic mother plants. If you want to buy a Trichocereus pasacana, you usually get very small plants and seedlings that will take many years to get tall. A large Trichocereus pasacana mother plant can cost 1000 bucks and more if you buy it from a professional landscaper.
