Trichocereus schoenii , also known as Echinopsis schoenii under current nomenclature, is a south Peruvian Trichocereus species that Backeberg described and named after E. Schön, who assisted him financially on his trips. Mr. Schön was from Arequipa, which is where one of the most important habitats of this species is. However, the species is not limited to that area and grows nearby other South Peruvian Trichocereus species. Trichocereus schoenii usually grows in the company of some Corryocactus species and there are also some other Trichocereus species that grow at the same sites.
Trichocereus schoenii resembles Trichocereus santaensis, but differs from it by the long central spine and a slightly different areole shape and rib shape. You need to look very closely to tell them apart, and it´s usually the typical spination that allows you to recognize it as what it is. It´s a very rare and beautiful species which is very rare in cultivation. The plants that are available are usually mislabeled and are usually identified as Trichocereus cuzcoensis or Trichocereus knuthianus.
Trichocereus schoenii is a plant that roughly belongs to the Trichocereus cuzcoensis complex, but there are many differences and I hope to see some cladistic studies about this species one day. The species usually has seven ribs (as seen in the photos) and the spines can get up to 8 centimeters long. You can read a more detailed description including some habitat photos in my book.

Trichocereus peruvianus / macrogonus from Matucana Red Spines
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. Da eine genaue Bl.-Beschreibung nie erfolgte, gebe ich hier eine solche von einer Bl. (mit Foto) eines Exemplars östlich von SAMNE, Prov. OTUSCO, Depart. La Libertad, wo beide Formen mit Übergängen zusammen wachsen. Bl. seitlich, nicht sehr weit unter dem Triescheitel, ziemlich waagerecht vom Trieb abstehend, 21 cm lang, mit einer Weite zwischen den äußersten Krbl. vonca 20 cm. Über dem Frkn. ist die Rö. leicht nach oben gebogen, während die Öffnung der Rö. wieder leicht nach unten gebogenist. Frkn. 22 mm lang und dick, grün, gehöckert, mit schmalen grünen Schuppen von unten 1 mm bis oben ca 4 mm Länge und mit reichlichen schwarzbraunen Wollhaaren. N.-K. 23 mm lang, aber nur etwa 5 mm weit um den Gr., blaß bräunlich, mit etwas Nektar. Rö. darüber 8 cm lang, Öffnung 4,5 mm weit, mit 6 mm (unten) bis 25 mm (oben) langen graugrünen Schuppen und schwarzen, 15-25 mm langen Wollbüscheln. Stbf. blaßgrün, nach den Enden hellgelb, der Rö. aufliegend, 8-10 cm lang, die des Saumes 4,5 cm lang, Insertionslücke 4 cm lang unter dem Saum, Beutel brauncreme, 2,5 mm lang, 1 mm breit, Pollen weiß. Gr. blaßgrün, 19,5 cm lang, wovon 3 cm auf die 15 hellgelben, überragenden Narbenlappen kommen.

This is the crowdfunding campaign post for our first Trichocereus book TRICHOCEREUS VOLUME 1: THE SAN PEDRO GROUP. This book has since then been published and can be found in our shop. All links below are no longer valid.
Example photo. Original not identical
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!
