Trichocereus pachanoi (Echinopsis pachanoi)

Trichocereus pachanoi, also known as Echinopsis pachanoi, is columnar cactus with a long history of being grown as a crop and ritual plants. Today they can be found in every South American country. It is endemic to Peru and Ecuador, where the type locality can be found.

Please note that this is a purely informational article and we do not sell any plants or seeds of Trichocereus pachanoi.

The official and currently valid name is Echinopsis pachanoi, which came up when Friedrich & Rowley made a poorly thought out merger of the genus Trichocereus with Echinopsis! Trichocereus and Echinopsis are closely related, but there are so many differences in regards to the flowers and the body that it makes no sense to use Echinopsis for all kinds of different plants, while the same authors support the differentiation of even closer genera like Loxanthocereus and Borzicactus. I would jokingly call the chaos around the Echinopsis names the dark ages of Trichocereus  taxonomy. Now after numerous cladistic studies that pointed out that the genus Echinopsis needs to be changed again, the opinion of many authors have shifted and experts like Joel Lodé went on to use Trichocereus again. The genus Trichocereus is not officially back yet, but it would be highly unlikely if it wouldn´t be brought back within the next 10 or 20 years.

Echinopsis pachanoi aka Trichocereus pachanoi is a VERY variable cactus. It is not easy to differentiate Trichocereus pachanoi from other atypical Trichocereus types, such as a short-spined Trichocereus peruvianus or very spiny specimens of Trichocereus scopulicola. One of the most common strains of Trichocereus scopulicola, FR991, is very similar to Trichocereus pachanoi. It´s actually not really important, but I want to include this interesting little piece of information to point out what other and extremely similar plants can be out there-

Echinopsis pachanoi, aka Trichocereus pachanoi, is a very fast-growing columnar cactus native to the Andean Mountains, where it grows between 2.000 and 3.000 meters altitude.

It´s natural habitat includes Argentina, Bolivia, Chile, Ecuador and Peru but the plant can also be found in countless cactus collections all across the world. It is very similar to its relative Trichocereus peruvianus, now called Echinopsis peruvianus/peruviana or Peruvian Torch. Some growers, including Friedrich Ritter considered them to be synonymous and I tend to agree with that opinion because I’ve seen how extremely variable this whole group of cacti can be. Its general appearance depends on the environment and the overall health of a specimen. Trichocereus pachanoi is a very important plant for the Peruvian natives and has been used for all kinds of purposes.

Traditional names of Trichocereus pachanoi:

Achuma, Wachuma, Aguacolla, Huachuma, Hahuacollay, San Pedro,

Description of T. pachanoi:

Trichocereus Pachanoi naturally occurs in Ecuador and Peru, but can also be found planted all across Peru, because it was considered a sacred plant for the Peruvian natives. Its stems are light to dark green, sometimes glaucous and have a diameter of 5 to 20 cm  and usually 5–8 ribs, depending on the size. The white or gray areoles can produce numerous spines, that can get up to 2 cm long or more, depending on the environmental conditions it is grown in. As already mentioned before, the plant can be totally  spineless. The areoles are spaced evenly alongside the ribs, and between 1 and 2 centimeters apart.

Trichocereus pachanoi grows like a tree and reaches sizes of up to 6 meters and in some rare cases, even more. The plant pups from the base and grows columnar, unlike the smaller, clumping species of Echinopsis. Trichocereus pachanoi is a textbook example of a columnar cactus. It is one of the most beautiful cacti that are out there. The skin color can vary greatly and while some of the Ecuadorian Trichocereus pachanoi have a bright green color, there are many glaucous types. Most collection plants lack the spines while the specimens in the habitat usually tend to have more spines. There even are forms which are said to be the wild, spiny form of Trichocereus sachanoi and which was probably brought into cultivation by Karel Knize. I once bought some of those “wild Pachanois” and they had very long and yellowish spines.

Flowers: White, coming out at the upper parts of the Columns. Trichocereus pachanoi is a night flowering and self-sterile species. That means it needs another pollen donor to produce seed. The flowers are very large and attractive, usually around 18–25 cm long and with a diameter of up to 21 centimeters. It produces green fruits that are up to 7 cm long.

The flowers produce a very pleasant smell. The sepals have a brownish/reddish color while the petals are white. The stylus has a green base. The tube is covered with gray/black hairs.

Type location: Ecuador, Chan Chan Valley.

In the original description, Rose mentioned that Trichocereus Pachanoi comes from the higher areas of the Andes, where it grows at 2000-3000 meters altitude. Britton and Rose considered Cuena in Ecuador as the location of the type. That means that the plants that can be found there are the most typical for their description. Trichocereus Pachanoi grows all across Ecuador, from the Chan Chan valley down to the large Armatocereus populations in the south. In addition, the plant can also be found all over Peru and those plants are usually wild forms.

Trichocereus Pachanoi was named in honor of the well-known cactus collector and taxonomist, Pachano.

Commercial names and synonyms

Trichocereus sp. Torres & Torres, Trichocereus huanucoensis, Trichocereus, Tom Juul´s Giant (which is probably just an Ecuadorian Pachanoi), TPM, Trichocereus HBG 53196, Loehmans monstrose Trichocereus, Trichocereus OST 90641, KK2150 Trichocereus, and so on. 

Cultivation: Trichocereus pachanoi is very easy to cultivate. It’s a plant take can take a fair amount of frost and that´s relatively frost hardy for a cactus. Short night frosts and short temperature spikes down to minus 5° Celsius shouldn’t be a problem for them, but it also depends on the general health of the plant. I do not recommend to leave it in wet soil for long if the temperatures are low. This is one of the plants that takes a lot of water when the temperatures are high. In summer, I water them weekly and fertilize them once a month. And they love it. They need to reach a certain before they will ìflower, but if you give them a large enough pot and sufficient nutrients, they will even flower without free root run. I can recommend a sandy, acidic soil that dries up very fast. That ensures that the plant is dry once you bring it inside to the winter storage. In some warmer countries, Trichocereus sp. can be grown outside and they usually take it very well. I saw beautiful specimens in Australia or California. The Only thing you need to be careful about is rain because they don’t like getting wet feet for a long time. They take it for a couple of days, but it´s best if to give them some rain protection and a covering sail to prevent them from being overgrown by moss and algae. During the growth season, Trichocereus Pachanoi can grow very fast if watered on a regular basis.

Ecuadorian Specimens of Trichocereus pachanoi

Trichocereus pachanoi can be found on all kinds of witches markets in Peru and Ecuador. Ecuadorian Pachanoi tend to have a distinct, bright green color and are among the most sought after Trichos that are. In general, Trichocereus Pachanoi makes a great grafting stock, because of its fast growth and frost hardiness. Below you can find photos of plants that are typical for the Ecuadorian phenotype. The plants are often surprisingly spiny, with rounded ribs and 1-3 longer spines on white felted areoles.

Diseases and how to avoid them

They are fairly resilient and don’t suffer from many diseases. They can suffer from bacterial or fungal rot every now and then and there are various pests & infections that growers can encounter. Black rot is usually benign and heals up after a while. There are fungal infections that can infect all plants from the genus Trichocereus, for example Witches Broom Disease, Damping Off or some other forms of orange rot. In many cases, fungal infections kill the plant within short time and infected plants should be removed from the collection immediately. Another common pest are root mealies, which are often brought into the collection through bought plants from online marketplaces and it’s hard to get rid of them once and for all. Chemical pesticides like Imidacloprid work very well but because they have a very bad impact on the beneficial insects like Bees and worms, I wouldn’t recommend it. Neem or Neem Oil works very well against all kinds of pests, including the hardy spider mites, Root mealies or scale. Scale can also be scrubbed off if the outbreak is not very bad. Trichocereus pachanoi should get a soil without too much humus because it tends to attract rot. Another natural pesticide that is used in organic farming is sulfur, which works against Spider mites and infections. Some growers also like to use diatomaceous earth to get rid of minor pests. Generally speaking, Trichocereus pachanoi is one of the easiest cacti that you can grow and most beginners shouldn’t have a problem to grow them.

Frost tolerance of Echinopsis pachanoi:

Trichocereus pachanoi is able to take short night frosts, down to -9° Celsius, which is 15.8° Fahrenheit. The minimum average temperature is around 10° Celsius or 50° Fahrenheit. Using Valerian flower extract is beneficial and can help to improve their resistance against frost.

General recommendations of things to avoid

A common thing that new growers like to do is taking too many cuttings to get a lot of plants very fast. I really hate because that will slow down the general growth dramatically. Very large plants grow much faster than small cuttings. If you really want to  produce a lot of them them (to get grafting stock, for example), make sure not to cut too small segments. The minimum length should be at least 30 centimeters long. That ensures that your cutting is growing fast and vigorously. Cutting a Trichocereus promotes pupping; but only if you don’t cut away too much. Small stumps will often struggle to survive if they werent in a great general shape when the cut was taken and it´s just something that I see a lot. Don´t mess too much with the pH level of the soil, because it can kill the plant if the pH is too high or low. They usually like slightly acidic soil. Don´t use regular plant soil because it contains WAY too much Humus or wood products for them. They might like it in summer but as soon as the temps drop, your plant might rot away because the roots take forever to dry. Don´t leave water standing in the pot because it will spoil the roots. Don´t spray them with oil and leave them in the sun directly after the treatment, because the sun will probably burn it. Only apply oil or alcohol in the evening when the sun cannot burn the plant and make sure not to directly expose plants that spent the winter in the house to the burning sun, because it will give it a sunburn.

Getting Trichocereus over the Winter: Most Trichocereus species can be overwintered in a bright place with a temperature between 10° Celsius/50° Fahrenheit. As long as the plants are in winter storage, they don’t require water because they go into dormancy. Because of that, they should be kept completely dry between October and April. Otherwise, the soil might spoil, what often leads to the death of the plant. Please note that this only applies to growers in Europe or similar country, where the strong night frosts and rain periods would kill the plants outside. Make sure to give them enough fresh air to reduce the risk of fungal infection. Most Trichocereus tolerate cold winter storage very well. Besides, this cold storage is the same that happens to them in nature and it increases their general ability to flower. Plants that are kept too warm all year round have trouble to produce flowers.

Just like the other plants from the genus Echinopsis, Trichocereus pachanoi is very easy from seed. But only if you know what you´re doing. I can recommend the takeaway-tech, which is a development of the Fleischer Tec. Mr. Fleischer was a cactus enthusiast that invented a technique in which he germinated cactus seeds in small glass jars with a closed lid. Now, there are those 250 ml Salad containers that can be used in a similar way and they work with many cacti. Now, the seeds need light to germinate. So you don´t cover the seeds with soil but sprinkle them on the soil. The seeds of Trichocereus Pachanoi are very tiny. As a soil, I can recommend a mix of standard sowing soil (not regular plant soil because sowing soil does not spoil so easily) and sharp coarse sand. This way, the chances for fungal infections are rather slim. In addition, you can add a fungicide right when you add the seeds. There are various fungicides available on the market. Just make sure to not use Sulfur or copper during the germination process. Sulfur works great to get rid of infections on adult plants; but it can kill every single seed in a sowing container. So don´t use it if you intend to germinate seed. You can ask your pharmacist about potential fungicides.

Now, after you mixed the soil, you put it in the small see-through container and make sure to even out the soil layer by slightly stomping the soil with another growing container. This is to avoid that the seeds fall into little cracks. The soil level needs to be straight to ensure that the seedlings have enough stability later on. After you consolidated the soil, you can sprinkle the Trichocereus seeds on top of the soil. Then, you get yourself a water sprayer, add in some fungicide or antibiotic solution (but only one that doesn’t kill seeds) and spray the whole thing very lightly. Trichocereus Seed does not take a lot of water to germinate. Make sure not to add too much water, because it WILL 100% kill them if the soil looks like a swamp. Besides, make sure to get yourself VIABLE seeds. There are many crappy seeds available on the market and many of them are not viable anymore. Trichocereus seed usually stays fresh for 5-10 years, but the germination rates are best during the first year. After you’ve sprayed the whole seed/soil mix, you can close the lid and take it to a bright spot, like a window or under an LED lamp. Light increases germination rates dramatically and I can only recommend you to get yourself an LED lamp. But I’d recommend you to get one that uses High Power LEDs and that has at least 150 Watt. From all the things I got myself, this was the thing that increased the germination rates the most. Don´t bake the seeds though; a light spot on the window is absolutely sufficient. Ideal germination temperature is between 25 and 30 degree Celsius. If the seed was viable, you will get some germinations within 2-3 weeks. If you get white mold on the seeds, they are probably dead. It does not help to leave seed wet for more than 6 weeks in order to “wait for germinations”. It’s rather counterproductive so if you don’t get germinations within 4-6 weeks, take off the lid, let everything dry out and then, restart again. Difficult or half-dead seed can be treated with Gibberellic acid to wake it up from dormancy. Besides, cycles of drying out and watering can help to bring back zombie seed to life.
If you get mold inside the container, take off the lid asap and water away the mold. At this point, you´ll have to leave the lid open and grow them without a lid. If you do that, they need to be sprayed with water on a regular basis to stay alive. Like, twice a day. But don’t keep them wet for long and ensure that the soil can get dry between the watering cycles. Otherwise, you might get fungus gnats, which look like tiny, see-through worms. In that case, let the soil dry out.

The small seedlings have enough nutrients to survive for a couple months, but it helps to fertilize them IN A VERY DILUTED CONCENTRATION every now and then. Don’t use the regular dose that adult plants get or they will die. Besides, don’t expose the seedlings to DIRECT sunlight or they will get sunburn and die. Well yeah, after one year, they should be big enough to re-pot them and single them out. If you encounter problems in your culture, just let me know and I´ll try to help you!

The flowers of Trichocereus pachanoi: 

The flowers are large, white, hairy and covered with scales. The color of the hairs is usually black or brown, while the color of the hair on the buds or flowers on the PC clone is mostly white and similar to that of Bolivian species like Trichocereus bridgesii.

Trichocereus glaucus – Echinopsis glauca

Trichocereus glaucus Echinopsis glauca Rodni Kisar

Trichocereus glaucus, also known as Echinopsis glauca, is a Peruvian Trichocereus species described by Friedrich Ritter. It might be synonymous with Trichocereus chalaensis, or at least related to it in some form. There are also Peruvianoids that are sold under this name and I occasionally encountered Trichocereus fulvilanus being sold under this name as well. The whole complex is chaotic and it´s hard to verify which plant Ritter´s description was covering.

Trichocereus glaucus – Foto: Friedrich Ritter

Origin of Trichocereus glaucus:

Peru ( South Peru ), Arequipa (Rio Tambo), Chile. In Chile, this plant is closely related to Trichocereus fulvilanus and Trichocereus deserticolus.

Description of Trichocereus glaucus / Echinopsis glauca:

Trichocereus glaucus Echinopsis glauca Auxin photo

Trichocereus glaucus can get between 1,5-2 meters tall and is a prostrate/creeping species that you often find hanging down slopes and cliffs. This trait is very distinct in the variety Trichocereus glaucus var. pendens. The color of the skin is very glaucous and small specimens look absolutely like the type of plants that are labeled Trichocereus macrogonus / Echinopsis macrogona today.  Spiny, dark blue versions from the complex around T. peruvianus. However, macrogonus grows columnar while this species tends to bend over with age. New growth is very glaucous.

Areoles of Echinopsis glauca:

The areoles are dark brown to gray in color and approximately 2,5 centimeters apart of each other. Similar to other plants related to Trichocereus peruvianus, the plant has a diameter of up to 10 centimeters and the areoles are gray felted. The spines look a bit like the ones on Trichocereus cuzcoensis and old growth has a typical satin white glow that is common on this species. Trichocereus glaucus has 6-9 ribs, 3-6 middle spines and 8-11 radial spines. The middle spines are 5-10 centimeters and the radial spines 1-2 centimeters long.  New spine growth is black to brown and turns gray with age.

Flowers of T. glaucus:

White, just like almost every other Trichocereus from this complex. The diameter is very variable and usually is between 15-22 centimeters. Trichocereus glaucus is a night-flowering species with green, round fruits. However, the hairy flowers usually stay open until the next morning.

Fruit of E. glauca:

Round, green, and 3 centimeters thick.

Type locality: Lower part of the Rio Tambo in the department Arequipa.

Trichocereus glaucus is very similar to Trichocereus chalaensis and grows in a similar way. We think that Trichocereus chalaensis might be synonymous with Ritter´s Trichocereus glaucus. Ritter´s field number of Trichocereus glaucus was FR270. We distributed seeds of Trichocereus glaucus various times in the past and all ended up amazingly beautiful. It´s a very nice species.

Buy Trichocereus glaucus seeds:

Trichocereus glaucus aka Echinopsis glauca is extremely rare and most plants on the market will probably come labeled as “Trichocereus peruvianus” or “Trichocereus macrogonus”. It is common occurence for some Peruvian cactus collectors to label all glaucous Trichocereus species with this name. This is obviously wrong and causes chaos. We sometimes have plants of this species in our Trichocereus Facebook group, which can be found here: https://facebook.com/groups/trichocereus

Cultivation of Echinopsis glauca:

Trichocereus glaucus is a very resilient grower and likes to be watered well in summer. In winter, they should be kept as dry as possible at around 10° Celsius. Seed germinates very well and the plant is usually very tough. That´s also caused by its drought tolerance, which is very typical for these kinds of plants. The species will probably tolerate temperatures between -5° to -7° Celsius over very short time, but I would not stress it and this also depends on many other factors, like general health and dryness. I would recommend keeping at no lower than 10° Celsius in winter.

Varieties of E. glauca: Trichocereus glaucus var. pendens. This variety does only grow hanging down cliffs and small hills. This variety only grows at one location in Chile and is extremely rare. This local population is in the south of Arica, Camarca in Chile. Backeberg suggested that this would be his Trichocereus uyumpaensis, but Friedrich Ritter vehemently disagreed with that. More information is necessary about this topic.

Translation of Ritter´s description (loosely)

This species forms shrubs the size of 1 – 2 meters and often several meters in diameter, sprouting mainly from shoots that lay sideways on the ground. This plant rarely pups from the top or upper parts. The shoots are 5 – 8 inches thick, erect, later lying in the lower parts, the new shoot blue-green, later gray-green.

Ribs: 7-9, very broad, obtuse, 7.5 to 13 mm high, 15-25 mm wide, notched, with transverse furrows that do not reach down to the separating grooves of the ribs,
areoles: grey felted, 1/2-3/4 inches in diameter, 1 to 2 inches free removal, let down by the humps in the notches
Spines: In the new shoot black to brown, becoming gray, straight, rigid
Marginal spines: 7-10, directed laterally, the lower and lateral 8 to 15 mm long, coarse needle-shaped, somewhat flattened, the upper the upper stronger and not sharply separated from the Central spines.
Central spines: 3-6, very spread apart, subulate in the middle, but usually closer to the top edge and almost in the position of an edge of spine, below 1.5 mm thick
Flower: Not far from the apex, 13 to 19 centimeters long, fragrant, opening in the evening, the morning still open,
Ovary: Green with fleshy green, narrowly triangular, 2-5 mm long, pointed scales and large scales raised bases. The flowers are covered with brown/black hairs.
Partition against the nectar chamber 3-4 mm thick, tube-shaped, 13 to 23 mm long, to the stylus 1to 2 mm wide, brownish, almost openly, with nectar

Tubes:

In addition funnel shaped, 40-65 mm long, the top 2 to 3 cm wide, pale green interior, exterior gray-green, with triangular points, 7.5 to 10 mm long, dark green scales and tufts of hair as on the ovary.
Stamens: white, greenish below, insertions missing on the top 2 to 3 centimeters of the tube to a ring on the hem, pouch pale brown, approximately at half height petals standing
Stylus: pale green, white or pale brownish above, 10 to 11 cm in length, with 14 to 18 mm fall on the 13-16 spread pale yellow stigma lobes, between the pouches or outstanding.

Description of Trichocereus peruvianus:

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.

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.

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.

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 pachanoi are 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.

TRICHOCER. PERUVIANUS nur als eine Form der PACHANOI ansehen, die entweder

PACHANOI sind typisch Ar. von 3-5 mm Dm., feine Rst. von wenigen mm

fehlen die St. völlig, oder sie sind nur an jüngeren Pflanzen vorhanden
und fehlen 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. kann bei
beiden Formen bis auf etwa 10 gehen, die Anordnung der St. und das
Größenverhältnis zwischen Rst. zu Mst. 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.

Trichocereus macrogonus – Echinopsis macrogona Mega Page

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

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

Currently valid name name:

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

T.macrogonus and its connection to Trichocereus peruvianus

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

Kiesling´s article on Cereus macrogonus

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

Trichocereus macrogonus is a very old name and since Britton and Rose came along with their description of Trichocereus peruvianus, the plants that used to be called Macrogonus were then treated as T. peruvianus. Due to the old age of the species name Trichocereus macrogonus, it is possible that it will be given priority over the newer name T. peruvianus IF the original description of T. macrogonus will be considered to be correct. Right now, this hasn’t been decided yet, but there’s a chance that this will happen.  However, many people want to keep the old name Trichocereus peruvianus just because it has a lot of history and traditions attached to it. The future of 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.

Trichocereus macrogonus in the Huntington Botanical Garden by Richard Hipp

Origin of Trichocereus macrogonus:

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

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

trichocereus rauh Trichocereus macrogonus Echinopsis macrogona

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.

Areoles:

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

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

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

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

Culture of Trichocereus macrogonus:

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

You can improve the drainage o

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.

ICARO DNA Trichocereus peruvianus (Echinopsis peruviana)

ICARO DNA is a strain of Trichocereus macrogonus/peruvianus from Peru. They are collected by the reputable vendor Julio from the Icaro DNA shop, who has been active for many years now.

Their strain is an extremely blue and spiny Peruvianus strain that comes from the Matucana region on Peru. Everyone who ever grew some of them knows that they are THE epitome of a non-cuzco Peruvianus.
The shop owner Julio & his ICARO DNA shop have been around forever and just earned a reputation for their consistently great quality.

The ICARO seeds were picked up by many shops and ended up being one of the more common strains around Australia and other parts of the world. Those plants are not clones, but grown from Matucana seeds which are genetically diverse.

Here are some pics for your viewing pleasure! The Photos were donated by Trichocereus.com.au, SAB member Getafix, Blowng,Naja Naja & Sebastian Preiss! If you want to see some more photos of Icaro DNA, check out our Trichocereus Facebook group: https://facebook.com/groups/trichocereus

SS01 (Trichocereus peruvianus)

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.

Sacred Succulents used this clone to create many hybrids with this clone. Check out the Sacred Succulents website.

Crowdfunding Campaign TRICHOCEREUS book VOLUME 1

Crowdfunding Campaign TRICHOCEREUS book VOLUME 1 2

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.

Crowdfunding Campaign TRICHOCEREUS book VOLUME 1

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:

https://trichocereus.net/product/the-san-pedro-group-book-trichocereus-patrick-noll

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 (Trichocereus peruvianus)

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.

ICARO DNA (Trichocereus peruvianus)

ICARO DNA (Trichocereus peruvianus)

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.

Trichocereus ‘BOGAN’ (Echinopsis)

The Bogan clone has one of the funniest backgrounds of all the clones that are known in the community. It all goes back to the year 2006, when the SAB Member DuG discovered a very cool type of (back then, suspected Trichocereus macrogonus) growing in front of a house and named it Bogan. He initially asked for a cutting (which he was lucky enough to get) and next time he got there, he realized that the large motherplants had been hacked down by the “bogan” homeowners. And not only had they hacked them down, but they also tried to burn them. He immediately asked if he could take them with him and they were more than happy to get rid of them…because…you know, cacti don´t burn so well. Here is DuG´s original picture on SAB just to show you how they were looking back then.

So far, I havent seen a flower pic but I will certainly update this page as soon as I get some. The plants usually have a very bright green epidermis and look very much like the Ecuadorian types. On the earlier pics, they looked a lot more like a peruvianus, but this clone shows it´s genetics on the young growth. But for a pachanoi, it can get very long spines and it definitely is a very cool plant!

Fields Macrogonus (Trichocereus macrogonus -Echinopsis macrogona)

Trichocereus Macrogonus Fields Echinopsis macrogona 0

Trichocereus macrogonus ‘Fields’, also known as Fields Macrogonus is a Trichocereus that was originally part of the legendary Fields collection in Australia. The collection was founded in the early days of cactus collecting. Most of the plants from Fields, including the Fields Macro, were brought to Australia through Harry Blossfeld´s South America expedition. This was long before all the import restrictions on plants and cacti were put in place. The garden is now owned by Robert Fields, who took over the garden from his father, the person who began with the collection. 

Now back to the history of the Fields Macro. Harry Blossfeld, who was a field botanist, offered some cactus shares to finance his 1935 South America Expedition and Mr. Field was one of the people who took the chance to invest in it. In return, he received some very cool cacti that grew in what is known as the “Field´s Collection”. In addition, Mr. Field seems to have bought some plants or seeds from Friedrich Ritter, because some of their plants were (at least officially) discovered by Ritter, such as Trichocereus knuthianus.

This Fields Macro, also known as Trichocereus macrogonus ‘Fields’,  is one of the oldest confirmed specimens of Trichocereus macrogonus that are labeled as such. Of course there are still plants around from the early days of cactus taxonomy, but the majority of them have lost their labels. 

At the time of the expeditions, Britton and Rose had just described their Trichocereus species Trichocereus pachanoi, Trichocereus bridgesii and Trichocereus peruvianus and Trichocereus macrogonus was still a very well known species, even more well-known than Trichocereus peruvianus. 

There are a lot of plants labeled Trichocereus macrogonus on the market today, but the great confusion surrounding the name makes it very hard to differentiate between the ones that were originally called Trichocereus macrogonus and the ones that modern nurseries or seed collectors just identified themselves. On the commercial seed market, you can get all kinds of different species under the name Trichocereus macrogonus and plants from the commercial market are generally unfit to be used as standard for Trichocereus macrogonus.

Most Trichocereus macrogonus strains from Peru usually fall into the species Trichocereus peruvianus, which is why I think both names are at least partially synonymous.

In addition, the original description of T.macrogonus was very incomplete. There is no country of origin, no good photos from the earliest examples of Cereus macrogonus, no Herbarium specimen, no early flower description etc.  

From the time when Britton and Rose described T. peruvianus, the original Trichocereus macrogonus was never found again and today no one really knows which plant was originally described in the description. And because of that, an early example of Trichocereus macrogonus that goes back to the 1930s is a great thing! If you are interested in the history of Trichocereus Macrogonus, check out my article here:

Trichocereus macrogonus / Echinopsis macrogona

Personally, I think the Fields Macrogonus looks very much like a Matucana Peruvianus such as Icaro DNA or Los Gentiles. This particular form of Trichocereus peruvianus has brown spines and is very close to the overall description of Cereus peruvianus.

LOS GENTILES Trichocereus peruvianus

The Los Gentiles strain is mostly known through the California based Nursery Sacred Succulents, who has been offering crosses with this type for years. They sell both seeds and cloned plants, which is why there is a large generic diversity.

LOS GENTILES is Trichocereus peruvianus / Trichocereus macrogonus strain with a frosty epidermis and the color of the spines varies between Gold and reddish brown. Most of the spines have black tips and the ribs indicate that it is closer to Trichocereus peruvianus than it is to other strains. It definitely is an interesting population and I will add further info about it later on.

It is very similar to Trichocereus peruvianus strains from the area to the area around Matucana. Outside the United States, this clone is rare. There are a few local populations that look very much like it.LOS GENTILES is NOT the same strain as Trichocereus peruvianus ‘Icaro DNA’, but these two strains are so similar that I am very positive that they come from the same area in Peru. Sacred Succulents are the only source for this type of Trichocereus apart from the people who bought them there and sold or traded them.
Trichocereus ‘LOS GENTILES’ is an extremely fascinating population. And even if that´s not the case, it still is a fantastic Trichocereus with a deep blue epidermis and strong spines that have written “Dangerous” all over them.

In my personal opinion, LOS GENTILES is the same population as ICARO DNA.

ROSEI 1 (Trichocereus peruvianus) Fields

Both Rosei 1 and Rosei 2 are among the most popular clones in the Trichocereus community. Just like so many great plants, they originated from the Fields collection in Victoria. The name was used in very old cactus literature to label a certain, very blue types of Trichocereus peruvianus / Echinopsis peruviana. This name was mostly applied to the same plants that we label as Trichocereus macrogonus today. The name is mostly synonymous with certain forms of Trichocereus peruvianus.

The name Trichocereus rosei was never an officially described species and that´s why we count both Rosei clones as commercial varieties. Both clones are part of the Fields collection and came to Australia in the early days of cactus trading. Mr. Fields was one of the supporters of Harry Blossfeld´s South America expedition and got the plants as reward for the support.

Despite the fact that Rosei 1 and Rosei 2 are actually clones, you can find very similar specimens in nature. In particular, we see a striking resemblance to the forms of Trichocereus peruvianus from Matucana (e.g. the Icaro DNA strain, Sharxx Blue etc).  However, there are also similar plants in other parts of Peru and we probably won’t be able to find out where exactly they came from. In the future, I will have a look at old cactus catalogs to see if there might be some old seed lists that include the collection sites. The only information that is certain is that both clones are from South America, but that´s a pretty big area.

Rosei 1 has shorter spines than Rosei 2 and usually has a more glaucous/blue epidermis. But because the environment can have a huge influence on the look of a plant, I doubt that this works reliably.

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.
