Trichocereus tarmaensis Rauh & Backeberg is a close relative of Trichocereus cuzcoensis that was described as a separate species. There are various differences between Trichocereus cuzcoensis and this species, and some forms of Trichocereus knuthianus are considered to be synonymous with T. tarmaensis as well.
Trichocereus tarmaensisreaches a size of 2 meters and is pupping from the base. It has 7-9 ribs that are approximately 2 centimeters wide, rounded at the top and with very distinct V-notches above the areoles. The areoles are approx. 2-2,5 centimeters apart with a diameter of 9 millimeters. Young growth areoles have a very fine brown wool that changes it´s color to a darker brown. It has 3-6 radial spines that are between 1 and 3 cm long. It often has one very large downward pointing spine that is up to 10 centimeters long. The plant usually has one of those middle spines. Old spine growth changes its color very soon to a gray, similar to what we know from Trichocereus cuzcoensis.
Flower of E.tarmaensis:
White, very similar or identical to some of the spiny forms of Trichocereus cuzcoensis or Trichocereus peruvianus. The tube has brown hairs and the fruit reaches a maximum diameter of 5 centimeters.
Central peru, Tarma in Peru at around 3000 meters.
Trichocereus tarmaensis looks very similar to Trichocereus tulhyacensis and both species are hard to distinguish if do not have the luck to observe them during the flowering phase . The flower of Trichocereus tulhuyacensis is pink, which is something that does not apply to any other Trichocereus species from this complex. If your Trichocereus has a reddish to pink flower, it´s not T. tarmaensis but Trichocereus tulhuyacensis or another close relative. Both Echinopsis tarmaensis and Trichocereus tulhuayacensis are very rare and mislabeled anyways. Karel Knize is selling seed of this type under the field number KK2148 .
Photos of Trichocereus tarmaensis
This picture shows a seedgrown specimen that was sold through the SAB shop in Australia.
When looking at this pic, it gets obvious that this type is VERY similar to some types of Trichocereus cuzcoensis, and even has similarities to a KK242. I do not think that specimens of KK2148 could be recognized as such without knowing the label. They are simply synonymous with some types of Trichocereus cuzcoensis. This species grows at around 3000 meters altitude.

Trichocereus peruvianus or Echinopsis peruvianais a columnar cactus that can get up to 4 meters long and reaches 20 centimeters in diameter. It´s also called the PERUVIAN TORCH cactus and is native in Peru. Britton and Rose – The Cact. II, S.136 /192
Most regional forms belonging to this species have a frosted blue color and grow between 6-9 ribs. Its flowers are white, though there are some close relatives that have a different flower color (Trichocereus tulhuayacensis). It usually grows upright, but sometimes grows prostrate hanging down from cliffs and rocks. The size and color of the spines varies greatly, but most of them have about 6-8 honey-colored to brown spines that can reach about 4 centimeters in length. The areoles are brown to beige-felted and up to 2,5 centimeters distanced from each other. The Spines do NOT have a knobbed Base. The spine color is one of the key traits if you attempt to tell it apart from Trichocereus macrogonus. We write more on Trichocereus macrogonus in that particular chapter.
A Peru at the type locality in Matucana.
Echinopsis peruviana flowers very easily as soon as it reaches a certain size and the plant is very easy to cultivate. Some of them have a distinct V-Notch above the areoles, but not all and it´s not a trait that is reliable for identification.
Cultivation of Trichocereus peruvianus / Echinopsis peruviana:
Trichocereus peruvianus can be grown from seed 0r propagated by cuttings. Seeds need to be sprinkled on top of the soil because they require sunlight to germinate. The seeds are tiny and only a few mm large and have a long viability. Usually, the seeds can stay viable for up to 10 years or above, though that depends on many factors. The Seed needs to be stored in a dry and cold environment to guarantee maximum viability.
Los Gentiles (Noah Reams)
The cactus can also be propagated through cuttings and it´s very easy to root. But make sure that the cuttings are not smaller than 20 centimeters because that stunts the growth tremendously.
The flower of Trichocereus peruvianus / Echinopsis peruviana:
The flower is white and reaches as size of up to 25 centimeters. Trichocereus peruvianus is a night flowering species.
Type locality of Trichocereus peruvianus / Echinopsis peruviana:
Peru (around Matucana). Trichocereus peruvianus is the dominant Trichocereus species in Matucana.
Plants that are closely related or are synonymous with Trichocereus peruvianus:
Trichocereus tacnaensis, Trichocereus puquiensis, Trichocereus santaensis (some of the plants around the Santa Valley belong to Tr. pachanoi though), Trichocereus tarmaensis (closely related to Trichocereus cuzcoensis as well), Trichocereus macrogonus, Echinopsis macrogona, Trichocereus f. Ancash, Trichocereus sp. Ayacucho, Trichocereus giganteus, Trichocereus longispinus, Trichocereus sp. Pamacoche, Trichocereus sp. Matucana, Trichocereus rosei,
Trichocereus peruvianus and Trichocereus pachanoiare sister species and closely related. Some field botanist considered them one large and variable species and there are countless intermediates and hybrids that could be placed in either species. Around 1950-1980, some authors came up with a large number of unnecessary species names and most of these plants would fit into the description of Trichocereus peruvianus as well.

Culture of T. peruvianus:
The culture of Trichocereus peruvianus is not very hard. The plant has very similar requirements as other Trichocereus species like Trichocereus macrogonus or Trichocereus pachanoi. Trichocereus peruvianus is an extremely frost resistant plant that can thrive in the most difficult environment. Some of its forms grow columnar while some others are creeping/prostrate. In their natural habitats, they even hang down on hills or rocky slopes. When watering cacti, the soil should not stay wet for more than a couple of hours because it greatly increases the probability of rot. Cacti need a substrate that dries out fast and too much water is often deadly for them. Apart from a little bit of water here and there, you should only water Trichocereus peruvianus when it´s warm. During the hot growth-season, they can take daily or weekly watering and like to be fertilized on a 7-14-days schedule. I even fertilize weekly during the main season, but that also depends on your personal way of growing cacti. It’s best to use a mineral substrate like Pumice or Lava, with additives like Coir, Sand, Sowing Soil, Expanded Clay etc. Just make sure to add in a very small part of Coir or Humus because it helps to solidify the soil and increases the cactus ability to take in nutrients. I personally love Lava and Pumice and the plants enjoy it very much! Echinopsis peruviana aka Trichocereus peruvianus likes a sunny place in half-shade, but not full sun. They can take it if they are used to it, but it increases the risk of sunburn. Especially directly after the winter period when they are not used to it yet.
Winter & Frost Protection: Trichocereus peruvianus is a relatively frost hardy cactus. It’s usually not a problem for it to take take a little night frost here and there and is tolerant down to -9° Celsius. But that’s really the limit and I would not be comfortable to push it below that. There are always plants are less frost tolerant than others and you never know where the limit for your plant is going to be. A plant that spent its life in a heated greenhouse, will die very soon if you suddenly start exposing it to cold winter frost. The cacti need to be hardened up and in a good general health. In my greenhouse I overwinter Trichocereus at 1° Celsius between December and March.
Minimum average winter temperature:
The ideal average winter temperature for Trichocereus peruvianus is 10° Celsius. That´s close to their natural winter period in habitat. Trichocereus peruvianus can compensate short frosts down to 15.8° Fahrenheit every now and then but you should take care that it has an average temperature of around 50° Fahrenheit.
Winter storage & Winter Protection for Trichocereus:
Trichocereus peruvianus needs fresh air during the wintertime if you want to overwinter the plant inside. It also needs light and the soil has to be completely dry, to make sure that the rootstock does not rot. This is important because that’s exactly what happens in the habitat during the winter time. Trichocereus peruvianus can deal with low temperatures as long as its dry. Of course all those overwintering-rules only apply of you live in a country with hard winter frost down to -20° celsius and lower. If you live in a warmer country such as Australia, this certainly is not a problem for you and water or high air humidity are the bigger problem then. I also know many growers from the CA area in the USA, and they usually get their plants over the winter without problems, if they do nor get surprisingly cold frosts. Leave your Trichocereus peruvianus in a bright room, give it a little bit fresh air every now and then and make sure to keep the temperatures below 10° Celsius. As soon as you put them in a heated room, they will require regular waterings and light or they will die quickly. In addition they will etiolate. If kept dry, the water requirements during the winter are minimal though. The minimum temp in Fahrenheit is 50° Fahrenheit. No water should be given between late autumn (October-early May) unless you grow them in a heated place, eg greenhouse or house. If you are lucky enough to have a greenhouse, you can take out most Trichocereus in early March, but you should also check the maximum frost tolerance of the species you take out. There are many cacti that need higher temperatures to stay healthy.
Germinating Trichocereus peruvianus seeds:
Just like Seed of other Trichocereus species, Trichocereus peruvianus seeds need light to germinate. I usually prepare a mix of Pumice, Lava, Coir, and Sand and and sprinkle the seeds on top of the soil. Make sure not to knock off the sowing container/pot because that would probably bury the seeds and that’s never a good thing. Buried seeds often do not germinate due to the lacking light or they germinate deep inside the soil and die. So yeah, sprinkle them on top of the soil and make sure that the temperatures are between 26° and 30° Celsius. Make sure to add in enough water to start the germination process. However, it does not take a lot of water to kick start the germination and it’s always better to give very little water early on because you can always add in some more. But if you add too much water in the beginning, it cannot be undone without risking to wash or soak away the seed with the excess water. With a syringe, excess water can be removed from the sowing container. Put the sowing containers in a bright and warm place and be patient. A window sill works perfectly. You can also use a LED lamp to give them enough light to germinate and I can recommend that very much because it increases the germination rate. Adding a decent LED Lamp (like 100 Watt and above) will increase germination rates dramatically and the plants are healthier and grow faster.
Germination of seeds and why some seeds don’t germinate
The problem with seeds is that some shops resell seed from South America wholesalers that sell over-aged seed. So the shops might not know about the bad germination rates that their seeds have and that´s a real problem with Trichocereus peruvianus seed on the market. If you did everything I just mentioned and your seed does not germinate within like 2-6 weeks, it´s most likely old garbage. It does not help to keep it wet for longer than that because that’s not how germination of cactus seeds works. Instead, you let it dry and start another cycle once the soil is completely dry. It does not help to keep dead seed in germination chambers for 6+ weeks. You will just grow Algae and Moss. Another problem that you can get with commercial seed is that there´s a lot of misidentified seeds of this species available on the market. The people who collect these seeds usually don´t have access to literature and that´s why the misidentification rate is extremely high. . Many Trichocereus cuzcoensis are sold as Trichocereus peruvianus and that´s a big problem for the seed market.
My best recommendation is that if you can get in touch with the seed producer, send them a message and ask about a pic of the mother plant. That way, you can minimize the risk of getting mislabeled seed.
Seed Viability of Echinopsis peruviana/ Trichocereus peruvianus:
The seed of Trichocereus peruvianus is viable for many, many years. I sometimes successfully germinate seeds that are more than 5-10 years old but it always depends on the storage and the seed. Some are dead within a couple of months while some can even stay viable for decades, like Ariocarpus seeds. The bigger the seed, the longer they are viable btw. Rebutia are dead within a couple of weeks, Trichocereus & Echinopsis 5-10 years, Ariocarpus 10+ years, Echinocereus (5-10 years), Lophophora (2-5 years at max).
How to differentiate Trichocereus peruvianus and Trichocereus cuzcoensis?
The swollen spine bases of Trichocereus cuzcoensis are the main trait that Britton and Rose used to tell them apart. Trichocereus peruvianus does NOT have swollen spine bases. There are many intermediates and forms in between the two, but in regards to the original description that’s the most important trait. In addition, Trichocereus cuzcoensis only grows in Cuzco. There are relatives of Trichocereus cuzcoensis that can be found in other parts of Peru however, e.g. Trichocereus knuthianus, Trichocereus schoenii, etc
How to differentiate Trichocereus peruvianus and macrogonus
Both species are probably synonymous. Trichocereus macrogonus was used for plants with dark brown or red spines, while plants with different spine color were seen as Trichocereus peruvianus. The original description of Trichocereus macrogonus is ancient, lacked important traits or information such as country of origin and the original plant was never found again afterwards. Technically, Trichocereus macrogonus is the older name and might replace Trichocereus peruvianus as official name one day (IF the problematic description will be accepted). Some authors have already started to use this system, but is unclear if it will be accepted officially. Modern taxonomy moves towards fewer species, with a larger number of subspecies or varieties and I completely support that.

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

Videos of Trichocereus peruvianus / Echinopsis peruviana
Trichocereus macrogonus, also known as Echinopsis macrogona, is a columnar cactus.
The first description about it was made using the name Cereusmacrogonus 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.
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 this species s is unclear and will be decided in the next years. Personally, I consider the name 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.

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.
Backeberg´s and Rauh´s Photos
And this pic is from Backeberg´s description and shows a plant that is very common in European collections!
Echinopsis macrogona or T. 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.
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 sterilewhat 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
The importance of 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.
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
This is a completely informational page and we do not sell seeds or plants of this species. 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 though. Trichocereus macrogonus and Trichocereus peruvianus are at least partially synonymous and sellers use both names interchangeably.
This here is what grows out of Köhres or Knize Trichocereus Macrogonus Seed:
Trichocereus macrogonus ‘Fields’
The Fields Macrogonus is an old Australian Trichocereus macrogonus clone that came to Australia through Blossfeld´s first South America expedition. Harry Blossfeld was a cactus collector that financed his expeditions by selling cacti to financiers, and that´s how it probably was with the Fields Macro.
European Macrogonus Clone
Different phenotype, associated with Trichocereus macrogonus.
Red or brown spines are an important way to differentiate between them.
Aerial roots of Trichocereus macrogonus
Good example of a Bolivian Trichocereus macrogonus sourced from Karel Knize. The plant is almost certainly a relative of Trichocereus werdermannianus or taquimbalensis.
Trichocereus macrogonus / Echinopsis macrogona ‘MG Red Spine’ (Rodni Kisar)
European Macro clone
Wild populations from Matucana that may or may not count as Echinopsis macrogona.

Huariquiña, not far away from Matucana. There are also some photos from that site from the Sacred Succulents Field Trip. Overall, this is a fantastic strain with beautiful plants that grow prostrate at times.
The Trichocereus peruvianus clones Rosei 1 & Rosei 2 are among the most interesting Trichocereus cultivars out there. Both are very glaucous with a dark blue skin. They have yellow or dark brown spines that often have black tips. The old spine growth looks very gray and the areoles are covered with very fine, white wool.
Trichocereus ‘Rosei 2’ was part of the legendary Australian Fields collection. Both Trichocereus rosei clones were brought to Australia by Harry Blossfeld, who was one of the first importers of cacti. . Prier donated some pics of the original mother plant at Fields and I am extremely glad we have them on the site.
“Rosei2” is certainly not a real species name and belongs into the context of Trichocereus peruvianus / Echinopsis peruviana. It is very similar to the dark blue Trichocereus peruvianus plants coming from Matucana and it´s possible that it was originally collected there. Either as seeds or as a live cutting. The spine color can be very variable and this clone is known to produce massive spines, which can be seen on some of the photos.
There are all kinds of Trichocereus hybrids out there and I am happy to show you a couple of the resulting crosses on this page. I will try to update this page as often as I can, to show you what others grew from a certain cross.
Now let me add a little bit of background info to give you an understanding how this breeding works in case you are completely new to this. Almost all Trichocereus species are self-sterile. That means that you need pollen from another plant to produce seed. The pollen donor needs to be genetically different from the receiver. Because of that, it´s not possible to cross two different cuttings from the same mother plant. If you list the parents of a cross, it looks something like this:
Trichocereus peruvianus x Trichocereus bridgesii
That simply means that the Peruvianus is the mother plant, while Trichocereus bridgesii is the Father. In most cases, the resulting offspring comes closer to the mother than to the father. However, there are a lot of exceptions to this and sometimes, the genes of the father are simply more dominant.
You can cross a whole lot of Trichos with each other and most of the crosses will work, if you did it right. But there are some crosses that just genetically don´t match. For example, the seedlings produced by that cross end up being variegated/albinos or simply die. That´s actually very common and can happen all the time. It happens the most when crossing plants like Hildewintera hybrids. And that´s probably because there werent many plants in the gene pool to begin with.
Most Trichocereus species have a white flower and apart from the extremely rare Trichocereus tulhuayacensis, all San Pedros are flowering white. Because of that, this community is trying to breed some San Pedros with colored flowers. There already are a handful of hybrids involving Echinopsis pachanoi with colored flowers. One such Trichocereus hybrid is called SAARWELLEN and the other one is AMUN-RE. But both Trichocereus hybrids are extremely rare.
Now, have a look at some of the photos of Trichocereus hybrids

KK242 Trichocereus cuzcoensis is a collection number by the Peruvian seed & cactus seller Karel Knize. He is know for his many Trichocereus species and KK242 was one of them. But it´s not actually a species because we grew all kinds of different species from those KK242 seeds. Most were Trichocereus cuzcoensis, but that´s definitely not the complete story.
Most of the plants labeled as KK242 are representative for a very typical Trichocereus cuzcoensis. However, the KK242 is simply a collection name that stands for the area where the plants come from. And within that area, there are all kinds of different populations and all were sold using the same name. Imagine you live in a town and every plant is given the same collection name. That is what´s actually going on with KK242. Like already mentioned, the largest part of the plants labeled KK242 are Trichocereus cuzoensis. That is also because the name became the archetype of a typical Cuzcoensis and there are many people that label every one of their cuzcoensis plants “KK242”.And that´s neither correct nor practicable.
Now, most of the KK242s on the market were distributed by Knize´s website. If I remember correctly, none of the KK242 sold was actually labeled as Trichocereus cuzcoensis.
Those are the KK242 collections that I know of:
KK242 Trichocereus peruvianus – Matucana (frosted stem, brown spines)
KK242 Trichocereus peruvianus – Rio Chillon (from central Peru)
KK242 Trichocereus peruvianus – form. Langa
KK242 Trichocereus peruvianus – Rio Lurin (please note that the Lurin Trichocereus is actually a peruvianus, despite it being labeled as KK242!)
KK242 Trichocereus peruvianus – Huancavelica (which probably is a Peruvianus too)
Please note that apart from those different collection sites, there were cuttings and seeds from all kinds of mother plants sold and distributed throughout the world. That means that seed labeled as Kk242 can produce all kinds of plants, not just the KK242 Cuzcoensis.
Where to buy seeds and plants of KK242? : Well, if you are looking for a KK242, it is your lucky day. And that is because they are everywhere. On Ebay, a large part of the Trichocereus species sold are actually KK242s. Nonetheless, there also are other cuzcoensis varieties that you can encounter and many of them might even be labeled KK242, though they actually are a different cuzcoensis type from another location. And that´s why the bad image that the species Trichocereus cuzcoensis, or the KK242 in particular, receives is not justified. They are wonderful and amazing specimens and have such a great diversity that it´s totally not fair to reduce KK242 to that well know cuzcoensis type from Matucana. Some seed sellers might even have some KK242 in stock (and potentially labeled as Trichocereus peruvianus) though they are not aware of it. Most seed collectors or seed producers just label them “Trichocereus peruvianus” and since they don´t have the space or the funds to grow them all before they offer the seed, they don´t or simply can´t test it. Many people that sell cactus seed are still poor and they neither have the funds to grow them nor the knowledge to ID them. Of course, there are very skilled Taxonomists and Botanists from countries like Peru, Argentina or Bolivia. But there also are many people selling seeds or cuttings that are not.
Mislabeled seed is a problem that almost every seed salesman has to face from time to time and I know of a couple of cases in which large shop owners stopped doing business with certain collectors/wholesalers who sell mislabeled seeds that brought them into trouble with their customers. I recently came across someone who was pretty pissed for receiving a KK242 instead of the Tr. Peruvianus that he ordered. And with a good reason. But I guess it comes with the job that stuff like this happens from time to time. And if I were in the position of someone who ended up getting a cuzcoensis instead of a peruvianus, I´d just message the seller and explain the problem. You know, there are so many different types, varieties, and even intermediates, that it´s sometimes impossible to draw the line somewhere. Again, Trichocereus cuzcoensis is SO MUCH MORE than just KK242. And there are countless peruvianus types that are somehow related to cuzcoensis and show or two traits that are typical for cuzcoensis too.
Most wholesale seed collectors label their plant “Trichocereus Peruvianus” and keeping in mind the current taxonomy (which tends to merge the plants into a bigger species), it might even be the correct taxonomical label. Personally, I think a shop owner should add as much information about the background of a plant that he has, in order to give the customer a vague idea of what he can expect to grow. But since that´s not always possible (due to collectors just not labeling plants right) it´s the stuff that will always happen. And usually, that´s not because the seller is greedy SOB who wants to rip-off his customers, but because there aren’t so many people around who can keep peruvianus and cuzcoensis apart. Those collectors rarely are skilled with ID and though they sometimes know how the type they collect seed of is called by the locals, it´s far from being reliable. There are cuzcoensis forms available from Peru that come labeled as Trichocereus macrogonus or Trichocereus peruvianus. Because that´s how the other collectors labeled them. And chances are that other collectors will use the same name in the future, whenever they collect seed of that plant.
It´s not hard to recognize the KK242 cuzcoensis, but as I already said…where to draw the line? There are so many intermediatory forms that it´s kinda pointless because you´ll end up calling some perfectly peruvianoid types a Trichocereus cuzcoensis, just based on the fact that it has a couple characteristics that also exist on a cuzco.
Most of the people who offer “cuzcoensis” labeled as “peruvianus” probably weren’t even aware of the fact that their plants are more on the cuzco end of the spectrum. And since modern taxonomy went on to merge a lot of those species into the larger ones like “peruvianus” and “pachanoi”, this might happen a lot more in the future. And when dealing with seed collectors that visit local populations in Peru, Bolivia or anywhere else in the world…it´s rare that they include the collection sites with their seed or even add pics. I know many wholesalers, who have to grow their seed just to know what type they have bought. And if you keep in mind that some of those plants will take 3-5 years until they are big enough to say anything about the local population, it get´s obvious that the remaining seed would have already become unviable in the meantime. And that is a problem that will never really go away. Of course, it´s actually a pretty bad situation but the short lifespan of some seeds is the reason why there are so many shaky ID´s when buying seed from Peru; or other areas where cacti are grown as commercial crops. But despite the fact that it can be frustrating to find out that you ended up buying mislabeled seed…I still prefer it to getting unviable seed. Because thats the only thing worse than getting mislabeled seed.
So yeah, always ask where the seed is coming from. And ask about how fresh it is too! An honest seed supplier is EXTREMELY important because when growing plants from seed, a lot of this is based on trust. From all the cactus seed, I bought in my lifetime, at least 1/3 was unviable or misidentified. And as a buyer, that´s something that you can´t prevent. Some crosses just are bad or are a genetic mismatch. Or, some seeds are just too old.
So yeah, if there are issues with seeds contact your seed supplier and tell them/ask for a replacement. Not only can you help to weed out unreliable suppliers but you give the store owner a fair and honest feedback. KK242 Trichocereus cuzcoensis is a type that is notorious for having a whole lot of bad seed available on the market. I honestly only heard about one or two people who successfully raised some of them from seed. One of them is the SAB store by the way. Apart from the two I just mentioned, I only heard of unviable KK242 seed. That doesn’t mean that there is/was no good KK242 Trichocereus cuzcoensis on the market…but please be careful when buying this type of seed because a lot of it is, well let´s call it “difficult”.
I have many pics on this website and most of them include data about where the plants are growing. It´s not always possible to guess how a seedling might look like in the future, but the collection site is a good starting point.
If you have pics of different KK242s, please let me know our Trichocereus Facebook group and I´ll add them to the site.

Another type that Knize sold as KK242. Please note that this plant looks nothing like the KK242 Cuzcoensis. It´s possible that it is related to the more Cuzcoensis type KK242, but it´s a great reminder that KK242 is nothing but a “location” and not, the plant!
The plant above is what was grown from KK242 Seeds from JLH.
KK242 – Rio Lurin or Lurin Valle
This Form is a Plant that is very different from the KK242 Cuzcoensis that became so common around the World. It´s more of a standard Trichocereus Peruvianus and looks absolutely stunning as an Adult Plant! Great Type!
TRICHOCEREUS KK242 Bridgesii
So this Peruvianus was grown from a KK242 Seed Bag. It is obviously not the typical Cuzcoensis Type Tricho so i found it noteworthy to add this plant.
Trichocereus peruvianus from Matucana is one of the most sought after types. Matucana is the type locality of Trichocereus peruvianus, which means that in Matucana you can find the most typical plants according to the description. The description was originally made by the Americans Britton & Rose, and the described a plant that must have been somewhere between Trichocereus peruvianus and Trichocereus cuzcoensis. And yes, Trichocereus cuzcoensis plays a part in the history of Trichocereus peruvianus as well. Both are so closely related and exist with many intermediate forms in between that Britton & Rose´s decision to keep them separated from each other was not regarded without criticism.
One of the most typical Matucana Peruvianus types is the ICARO DNA Peruvianus. Icaro Dna made a name for themselves providing great quality seeds that are probably as true as it gets to the original description. To me, when I hear the name MATUCANA, I think of this remarkable type.
Some more Matucana Peruvianus types are the LOS GENTILES Peruvanus from Sacred Succulents and my own Matucana Peruvianus in my shop! Sorry for the promo, but it´s super high quality seeds that you will love!
But now back to the Matucana Perus. Sacred Succulents had the great luck to visit some of them during their South America Field Trips. Here are some of them:
Trichocereus peruvianus, Matucana, Peru
Trichocereus Peruvianus without a field number. Again in Matucana Peru. Very cool Glauceous Tricho, similar to the cultivar Trichocereus Rosei or Trichocereus Glaucus. Pic: Ben Kamm, Sacredsucculents.com! Please support them because they are awesome!
BK08612.4-A Trichocereus peruvianus, Matucana, Peru
Another frosted Peruvianus from the Location in Matucana. Very similar to the Plants that are labeled “Trichocereus Rosei”. Or Trichocerus Glaucus! Pic: Ben Kamm, Sacredsucculents.com!
Another type that is believed to be a Matucana type is the Australian Trichocereus rosei clone. It´s fabulous and one of my absolute favorites. Rosei 2 is DEFINITELY a Matucana…and Rosei 1 most likely. The alternative would be that it comes from Rimac, but I want to show it here too!
This is Rosei 2, just for comparisons:
Some of those plants are sometimes called Trichocereus santaensis, but those are usually thinner and overall closer to Trichocereus pachanoi or sometimes even Trichocereus bridgesii than they are to Trichocereus peruvianus.
Well, that was one of the more typical Trichocereus peruvianus from Matucana. This city in Peru is one of the historic cactus sites, especially for the species Trichocereus peruvianus. Matucana is the type locality of Trichocereus peruvianus, which means that in Matucana you can find the most typical plants. But there is more; many many plants with cuzcoensis genetics. For example, KK242 is from Matucana too! And due to the high number of intermediates between Trichocereus cuzcoensis and Trichocereus peruvianus, it´s sometimes not easy to draw a firm line between them.
This photo shows a fairly typical KK242 from Matucana. The photo comes from K.Trout and his website troutsnotes.com.
And now compare this to this other plant from Matucana:
It´s funny…but that one was sold as KK242 from Matucana too. Just to give you an understanding of what is actually out there.
SS01 (Trichocereus peruvianus) was brought into cultivation by Sacred Succulents. It is one of their oldest clones, going back many years and the number of hybrids that involves it is really high. It actually is a very blue Trichocereus that would usually be called Tr. peruvianus or Tr. macrogonus outside the SS nursery. The origin of this plant is unknown, but because of Sacred Succulent´s constant work with this clone, it is widely distributed.
Here is an excerpt from the Sacred Succulents description of SS01:
SS01 (Trichocereus peruvianus )
Columnar cactus up to 8´+ tall. Fat blue-green stems up to 6″ in diameter and 2″+ spines. Huge white nocturnal flowers. Can grow very fast; up to several feet a year. Tends to grow prostrate with age. We believe this to be a clone of either Trichocereus macrogonus or Trichocereus peruvianus. Cold hardy to 25° Fahrenheit.
My personal impression of this plant is that it is one of the plants that were originally sold by Karel Knize. Those were really common at the time this clone showed up and I would not be surprised if it was one of them.
Sharxx Blue is a short spinedTrichocereus peruvianus clone that was named after SAB Member Sharxx. It originated from the well known DAWSONS cactus collection and was distributed and named by PD (another SAB member). It probably is some kind of Trichocereus peruvianus from Matucana, very much like ICARO DNA, the Los Gentiles, Rosei or the many other Matucana Perus.
The plant is extremely blue and glaucous. Overall, Sharxx is one of my all-time favorite Trichocereus clones and it’s a very popular among Trichocereus breeders.
This clone is sometimes available from Australian growers that gift or trade away cuttings every now and then. If you are interested in a cutting, you might try to make a posting at the SAB forum. There also are growers that use it to produce Trichocereus hybrids. This year was the first year that Misplant offered some crosses with this clone. It is also available from Trichocereus.com.au, who donated the pics below.
This is the crowdfunding campaign post for our first Trichocereus book TRICHOCEREUS VOLUME 1: THE SAN PEDRO GROUP.
Hi guys, I just wanted to take the time to let you all know about the status of my crowd funding campaign for the printing costs of my book TRICHOCEREUS VOLUME 1: THE SAN PEDRO GROUP. Until 2016, this book was available exclusively through my Indiegogo campaign here: https://igg.me/at/2h2Jsr6XawQ/x/13533390.
The campaign is now closed, but it is now up for sale in our shop here:
I´ve been working on this book for a few years now and it´s finally getting close to a release date. It´ll have more than 300 all-color pages and will contain hundreds of color pics showing plants from the San Pedro Group in the habitat, botanic gardens and collections worldwide. There were dozens of well known people helping me with photos for this book and I am extremely proud that I was given the chance to write it! I´ll make sure it´ll be a high quality book that will look awesome on your shelf! There will be descriptions, photos and cultivation advice as well as a detailed guide on how to germinate difficult seed. The book takes a close look at flowers, fruits and old names that are no longer valid. This book contains a whole lot of different species and commercial varieties like Trichocereus pachanoi, Trichocereus peruvianus, Trichocereus bridgesii, Trichocereus scopulicola, Trichocereus tarmaensis, Trichocereus cuzcoensis, Trichocereus huanucoensis, Trichocereus pallarensis and many, many more!
The printing costs are somewhere between 10.000 – 12.000 Euros and that´s why I started the campaign on Indiegogo two days ago. Now after just 2 days, the campaign already reached 69% of its goal and is getting new supporters every single day.
The number of available books is very limited. There only are 250 softcover books and 100 hardcover books available exclusively through the campaign. The hardcover books already sold out but I managed to add a few that I actually wanted to put in the Trichocereus shop. Both the softcover version as well as the hard cover version are available for a reduced crowd funding price to say thank you to all the backers. The soft cover version will costs 58 Euro (+shipping costs) and the hardcover version will cost 88 Euro (+shipping costs). Both versions will be printed on high quality paper and with high quality ink. But because of the increased price of the hardcover edition, I could use an even better paper- and ink quality as well as some thread stitching to provide a higher value for the collectors. All the hardcover books are limited, numbered and signed as way to thank you for your support!
There also are package deals and re-seller packages to make it easier for shops or group-buyers to buy it. The books will be printed in June and the shipping phase begins in June or July. If you are not able to participate in the campaign due to whatever reasons, just let me know and I´ll try to find a way to make it work. It´s important to me that everyone who supports this project will actually get one.
Alright guys, it counts now and if I can´t get the campaign funded, the books won´t look as brilliant as they will when it reaches its goal. So please support my project on Indiegogo. The crowdfunding campaign will run for 60 days and I hope to reach the goal within the first 2-3 weeks. If you have any questions or just want to get in touch with me, you can reach me through EG [ät] trichocereus.net. You can also get in touch with me through our Trichocereus Facebook Group!
Sausage Plant is a very blue type of short spined Trichocereus peruvianus or some kind of Trichocereus pachanoi. The name comes from the “sausage-like” growth. It has the tendency to terminate its growth and pup again on top of the old shoot. That look can sometimes make them impression of a sausage.
It originally comes from South Australia, but there also are other sites where it can be found. That also includes the Fields collection.
Unfortunately, I do not have a good pic of this pupping behaviour, but it’s been reported from various growers that own this plant. It definitely is one of the most interesting Tricho clones out there and exceedingly rare in cultivation.
TPQC is another clone from SAB member Nitrogen. The ID of the species changed repeatedly in the past, but it is probably a Trichocereus peruvianus. It developed crested growth after an injury, but is generally not a crested clone and I have never seen one of the cuts revert back to crested growth. It is probably best to consider it a normal clone of Trichocereus peruvianus.
Photos of TPQC (Trichocereus peruvianus Quasi Cristata)
Nitrogen´s TPC, not to be confused with Nitrogen´s TPM, is a mutant version of a Trichocereus peruvianus or Trichocereus pachanoi that became known in the Trichocereus community after the US breeder Nitrogen has produced quite a few hybrids involving it. This resulted in a large number of mutant offspring that Nitrogen donated during his first and second SAB seed giveaway.
Nitrogen´s Trichocereus Seed giveaway
The seeds that he harvested from this plant were given away to friends and other growers and we hope to see more TPC (Trichocereus peruvianus cristata) offspring soon.
This plant was so mutated that even its flowers looked abnormal somehow. It´s very rare that mutated cacti are even able to produce flowers. And not only did this one flower, but also in the most spectacular way.
As you can see on the pics, the plant can grow crested and monstrose at the same time. In 2012, Nitrogen used a pollen mix of Tom Juuls Giant, SS02 and a SS02 hybrid with Trichocereus pachanoi to pollinate this plant.
Where to get a cutting of Nitrogen´s TPC?
There are many different types of TPC. It´s an abbreviation that simply means “Trichocereus peruvianus cristata”. However, this particular TPC is very rare and can only be found in Nitrogen´s garden, and in the collection of US breeder Misplant.
Nitrogen distributed all seeds he got from his TPC among the community for free, which is why they should be traded actively among fellow growers . If you own one of them, please consider taking cuttings and making them available. Because that´s what the purpose behind Nitrogen´s 2012 giveaway was all about. If you want to see more photos of Nitrogen´s TPC, make sure to check out our Trichocereus & Echinopsis growers Facebook group.
The ICARO DNA is not actually a clone but a seller who is very well know for it´s high quality Trichocereus seeds. The plants grow into amazingly dark to blue-green colored columns with strong spines. Sometimes, those spines are also dark brown colored and are among the most beautiful Trichocereus types I know. Personally, it´s definitely one of my all-time favorite cacti, simply based on the impressing look.
ICARO DNA sold a lot of seeds of this type in the past, which is why there is a large genetic variety available on the market. There also are certain clones that most likely were sourced from ICARO, such as the SHARXX BLUE or MAYBE the Rosei 2.
Apart from seedgrown material, there also is a relatively common clone that´s been traded around by people of the Trichocereus community, but the larger number of seedgrown plants make a differentiation hard.
I do have quite a few pics of this interesting type and I´ll post further updates about it as soon as I get more pics. Those been around for at least ten years now.
These picture were donated by Prier. Thank you very much!
Plants that look like this were oftenly labeled as Trichocereus macrogonus and chances are that you bought some of these labeled as such. Their cold hardiness and soil requirements are pretty much identical to the ones from other Tr. peruvianus.

The ones in these pics were grown in Australia, where this type is a bit more common than in Europe. If you are looking for one, just send me a message at EG[ät]trichocereus.net or you could try making a post in our Trichocereus Facebook group where it shows up every now and then as well.
