Trichocereus angelesii / Echinopsis angelesii or angelesiae

Trichocereus angelesii, also known as Echinopsis angelesii or Echinopsis angelesiae, was originally described by Friedrich Ritter as a white flowering variety of Trichocereus strigosus / Trichocereus strigonus, until Kiesling publicized it under the name Trichocereus angelesii.

The flower of Trichocereus angelesii

The flower of Echinopsis angelesii is white and 12-24 centimeters long. Trichocereus angelesii is a day flowering / diurnal species with clear visual similarity to Trichocereus strigonus. The spines, fruits and seeds are pretty much indistinguishable from the ones of Trichocereus strigosus, which makes it nearly impossible to identify the plant unless you find it at the original type location. Trichocereus angelesii, aka Echinopsis angelesii, usually has 14-22 ribs . In comparison to this, Trichocereus huascha has 12-15 ribs.

The typus location is Famatima in the provence La Rioja, what makes it likely that it is synonymous with the commercial name Trichocereus famatinensis. It is also closely related to the plant that Ritter called Trichocereus callianthus. This plant was originally sold by Ritter as FR999, which was still labeled as Trichocereus huascha back then.

Kiesling´s description gives Darwinia in Argentina as the typus location and it´s not clear whether or not those plants were actually the same.

It´s a rare species that you only get rarely, but classic Kaktus nurseries like Kakteen Haage or Uhlig Kakteen might have some of them available. If you don’t have the chance to collect them at one of the aforementioned locations, you will probably not run into it very oftenly. There are also some older plants that you can find on the commercial market, and these are usually labeled as T. huascha or Trichocereus strigonus. White flowering Trichocereus huascha might very well be a mislabeled Trichocereus angelesii.

Trichocereus glaucus – Echinopsis glauca

Trichocereus glaucus – Echinopsis glauca

Trichocereus glaucus, also known as Echinopsis glauca, is a Peruvian Trichocereus species described by 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.

Trichocereus riomizquensis RITTER (Echinopsis)

Trichocereus riomizquensis RITTER (Echinopsis)

Trichocereus riomizquensis is a Bolivian Trichocereus species that is closely related to Trichocereus bridgesii. I count it as a close relative and potential regional form of Trichocereus bridgesii, which is only endemic to one site in Bolivia near the Rio Mizque.
The species was discovered and described by the German cactus field botanist Friedrich Ritter, who gave Chuyllas as the type locality and described it growing on steep slopes in the province Campero.

His Field Number was FR 856. Friedrich Ritter was one of the leading Cactus experts of his time and successfully ran a seed shop, in which he sold this species as seed to people all over the world. Trichocereus riomizquensis was also visited during the Sacred Succulents Fieldtrips and they found a couple of different types growing around that area.

In Ritter´s book, he published a photo of this species. Unfortunately this photo is not very good and it is one of the species that are rare in cultivation. Almost all labels on plants grown from Ritter´s seeds are lost, but the plant is definitely available. On the market, it sometimes shows up labeled as Trichocereus bridgesii, or probably also labeled as Trichocereus PC. Please note that there is a wide variety of plants from this site and the range is very big, ranging from spiny to completely spineless plants.

Ben Kamm published some photos of a Herbarium specimen that was very close to Trichocereus bridgesii as well.

Where to buy seeds and plants of Trichocereus riomizquensis?:

Though Trichocereus riomizquensis is common in cactus collection in the USA, it is usually mislabeled. Sacred Succulents were giving away seeds after their Field Trips and some plants might have gotten into the hands of collectors. They are also selling live plants grown from their collected seeds sometimes.

Description of Trichocereus riomizquensis:

This is partial description of Friedrich Ritter´s original description, including remarks on how to keep it apart from T. scopulicola.

Trichocereus riomizquensis is 6-8 centimeters thick (while Trichocereus scopulicola is 8-10 centimeters thick), it has 5-6 ribs, (T. scopulicola: 4-6), its flanks are 2 centimeters wide (Scopulicola 3-4 cm wide flanks), the flanks are less rounded than the ones on Tr. scopulicola. It has rounded areoles (while the ones on T. scopulicola are usually oval). The areoles have a very visible fluff with a diameter of 2-3 mm. The 1-5 spines are honey-colored and between 1-3 mm long. Sometimes they are even missing.
The flower of Trichocereus riomizquensis is 20 centimeters long (while the flowers of T. scopulicola are 16-20) and covered with dark brown/white wool with large scales. The fruit looks knobby.

Type locality: Chuyllas near the Rio Mizque, on very steep rock walls in the province Campero, Bolivia. Discovered from Ritter in 1958 – FR 856.

BK10512.1 Trichocereus riomizquensis, Totora, Cochabamba, Bolivia

Trichocereus riomizquensis is one of the most interesting species from the Sacred Succulents Field Trips because of its incredible range. Some plants look like the Trichocereus bridgesii-type plants with long spines from the Field Trips and some other ones look like the short spine versions that Friedrich Ritter´s description was about.

If you take a close look at the whole appearance of this plant, you can see that it has a similar areole shape to the areoles on the well known Trichocereus PC clone, also known as predominant cultivar or predominate cultivar.  The flower and the overall appearance are so similar that everything else would be extremely surprising. Despite the fact that there are some very spiny plants at this site, there are some other which get extremely close to Ritter´s original photo. Though this will probably never be proven, there´s definitely reasonable doubt that this PC clone is actually a Trichocereus pachanoi.

There is a lot variation within the populations the original site near the Rio Mizque. This population is one of the most interesting Trichocereus populations out there and DNA testing should absolutely be made to look into its relationship to Trichocereus bridgesii.

Where to buy seeds or cuttings of Trichocereus riomizquensis:

Well, Ben and Sacred Succulents would be my starting point if I were in the USA. They don´t ship plants internationally, but if you have the luck to be in the country you might be able to get some cuttings. Apart from this, I do not know any sources for this species. Most of Ritter´s old plants have lost their labels meanwhile, which makes getting one even harden. I am sure that some of them show up on online market places labeled as Trichocereus bridgesii every now and then.

Trichocereus scopulicola / Echinopsis scopulicola Mega Page

Trichocereus scopulicola, also known as Trichocereus scopulicolus or Echinopsis scopulicola is a columnar cactus from Bolivia. It was discovered and described by Friedrich Ritter. Its current status is unknown, but it may be extinct in nature. 

Trichocereus scopulicola FR991 Rod

Trichocereus scopulicola FR991 (Rodni Kisar)

Synonyms of Trichocereus scopulicola:

Echinopsis scopulicola, Trichocereus cv. Super Pedro, Trichocereus scopulicolus, Trichocereus scopulicola NMCR, Trichocereus cordobensis, Trichocereus crassicostatus, Scop,

Origin of Trichocereus / Echinopsis scopulicola:

Trichocereus scopulicola was discovered by Friedrich Ritter during one of his expeditions to Bolivia in 1959. The location of the type is Tarija, Bolivia. More precisely, Ritter gave Tapecua as the location and assigned the collection number FR991 and sold seed of his discovery through his legendary Winter Seed lists. Because of that, he helped spreading the plant all over the world, despite the fact that Trichocereus sScopulicola is really rare in nature. There are very few collections of this plant in nature and I am always interested in obtaining seed from new scopulicola types. The plant grows in Tarija in the province O Connor. And no, this has nothing to do with Sarah Connor from the movie TERMINATOR. Trichocereus scopulicola grows in the cactus forests around the Department Tarija at around 1000-1500 meters.

Description of Trichocereus scopulicola:

Trichocereus scopulicola grows columnar like a tree and pups from the base. But it´s actually rare for this plant to produce numerous shoots and most plants don´t have any side shoots. Trichocereus scopulicola can get up to 4 meters tall though most specimens are smaller. The columns are between 5-10 centimeters in diameter and have a nice, dark green epidermis.


Trichocereus scopulicola can have 4-6 ribs though most specimens have five. The areoles are furrowed. The areoles are sunk in and have very little white fluff/wool on top of them. The areoles are rounded or oval and are between 1-4 mm long and 1-2 mm broad, which is very small for a Trichocereus. The distance between the areoles is between 15 and 30 mm. Areoles that form flowers have 4-5 mm diameter. Large, adult plants often lack the spines, while very young seedlings look remarkably similar to a Trichocereus pachanoi and can only be differentiated by the weird rib shape of Trichocereus scopulicola. Adult plants have (if they have any) 3-6 spines that are very small and up to 1.5 mm long. Seedlings have 6-7 ribs, areoles up to 2 mm in diameter and 3-5 mm away from each other, 7-14 needle-like spines (2-3mm long), of which two are central spines.

Flower of Echinopsis scopulicola:

Trichocereus scopulicola flowers from the apex but there are plants where the flowers come out from lower points on the plant. The flower is white and between 15-22 centimeters long. Trichocereus scopulicola is a night-flowering species but the flowers stay open until the late morning.

Fruit of Trichocereus scopulicola:

The fruit of Trichocereus scopulicola is green and can get up to 6 centimeters thick.

Friedrich Ritter considered this species to be very close to Trichocereus bridgesii, which is one of the plants that grow in the neighborhood of Trichocereus scopulicola. And it´s very likely that Tr. scopulicola is some kind of natural hybrid involving Trichocereus bridgesii or Trichocereus pachanoi.

In addition, Ritter wrote that Trichocereus riomizquensis is related to it, but not as closely related as Trichocereus crassicostatus is. These days, Trichocereus crassicostatus is generally seen as a synonym of Trichocereus scopulicola or Tr. pachanoi. So far, I´ve not been able to track a specimen down but they are certainly out there. If you grow one, let me know.

Cultivation of Trichocereus scopulicola:

Trichocereus scopulicola is similarly tough as Trichocereus bridgesii. The reason is simple; both come from Bolivia and are used to the same conditions. Bolivian Trichocereus species are very drought resistant, but can also deal with strong rainfalls in summer pretty flawlessly. However, they should not be watered when it´s cold and they prefer a purely mineral soil mix because that dries up a lot faster. During the hot summer season, they can be watered every few days when the soil has dried up again. Don´t water them when it´s cold or rainy because that can cause rot.

Winter protection and Minimum Temperature:

Scops are relatively hardy and can short night frosts of down to -5° Celsius and maybe even lower than that, but I would not test it out because low temps weaken the plants. The minimum average temperature should be around 10° Celsius and they should be completely dry over winter if you take the plants inside. If the get wet over a prolonged period of time, it can cause root rot or other infections.

Seed & live cuttings:

I get seeds every now and then and I know a couple of growers who actively breed with Scops. There sometimes are some available at SAB and the SAB forum. Besides, Misplant makes a couple Scop Crosses a year. This year, he made a pretty cool cross between a Scop and a colored Grandiflorus, which I can wholeheartedly recommend you because it might produce Scop seedlings with a colored flower.

Trichocereus scopulicola can be used as a grafting stock. It is a great stock that accepts graftings very easily.

The history of the PC Trichocereus clone – Predominant cultivar

The history of the PC Trichocereus clone – Predominant cultivar

I wanted to clarify some things about the PC Trichocereus clone. What it is, where it probably is from and what it isnt. The name is probably the most overused name in the history of Trichocereus culture. I personally hate it and spent days discussing the whole situation with friends or interested people in the Trichocereus Facebook group. If you hear the word PC in a Trichocereus group, JUST RUN. Log off, go outside and be in your garden. Still, if you actually wonder what those guys are actually talking about, I am happy to shed some light on this issue. Please keep in mind that I hate to use the name of this cultivar, strain or whatever you might want to call it and I will only mention this one time and one time only.

What does PC stands for? It originally means PREDOMINATE CULTIVAR. However, PREDOMINANT CULTIVAR would probably be more appropriate.

Now what is it really and is this all BS?

It is a clone, but there also are other plants grown from seeds that are probably coming from the same site this clone is coming from too. In California and parts of the USA, this clone is really common around parks, schools or gardens. It is very similar to most other San pedros, but it originally comes from Bolivia. This plant was originally collected by Friedrich Ritter and described as Trichocereus riomizquensis.

Trichocereus Riomizquensis 335This is the original photo from Ritter´s book. Do you see the white hairs on the flower and the way the areoles look? Well, keep in mind. You will need it later. Ritters official collection name of this plant was Trichocereus riomizquensis FR856 and they originally comes from Chyllas.

The original site is the Rio Mizque and we and my friends from Sacred Succulents visited the original site a couple of times.  It is extremely similar to Trichocereus pachanoi, but differs in substantial points like the hairs on the flowers and the overall rib structure. Though it is common belief that the San Pedro cactus aka Trichocereus pachanoi grows in Bolivia, all the San Pedro related plants we ever came across IN THE WILD either belonged to Trichocereus bridgesii or Trichocereus scopulicola. That also applies to the regional type from the Rio Mizque. I have all kinds of photos of those plants on the pages about Trichocereus riomizquensis and I don´t want to repeat this information here again.
This is a long-spined version of this but there also are a lot of short-spined ones on that site. I seen them. Just like this PC, they have 6-7 ribs, those weird areoles and golden spines without swollen spine bases. Overall, they are just a short-spined version of Trichocereus bridgesii.

Let me just say that one thing that the Bolivian Trichocereus species have in common is their drought resistance. They literally live in a hot desert and are a lot more resistant to drought than Trichocereus pachanoi or some of the other Peruvian San Pedros. And that´s where I want to draw the line directly to this Californian clone. Clones & cultivars are not humbug or bullshit….cultivars exist in EVERY field of commercial cultivation and everyone who tells you different is a fool. One such cultivar is actually this Tr. riomizquensis that was originally described by Friedrich Ritter. Is is extremely drought resistant and manages to thrive in the Californian climate. That´s why this plant is literally everywhere there. We tested it numerous times…almost none of those Californian plants were able to mate with each other…simply because they were genetically identical and cuttings of each other. I seen whole nurseries filled up with them because they are so damn easy to grow. They just cut them in small pieces and stick them into the ground. And after five years, they sell it for 30-100 bucks. All those plants share the same flower characteristics and are closer to Trichocereus bridgesii than they are to Trichocereus pachanoi. They are covered with white hairs, which is absolutely typical for Trichocereus bridgesii. I know a Bolivian Trichocereus species when I see one…and this PC is one without a doubt.

The flowers of the PC:

Do you see all those white hairs? Good, because it´s important to differentiate between certain Trichocereus species. Trichocereus pachanoi tends to have black or brown hairs, while this PC has white hairs. And that´s typical for the Bolivian San Pedro strains.

pcPachBudDSC_0462Those two photos are from Misplant.net! Check out their seeds because they are amazing.
Well, just compare the photos and see for yourself. The top photo is the flower bud of this PC Trichocereus and the lower one is a bud on a Trichocereus scopulicola. They are at different stages in their development, but I am sure you see the similarity in the important parts. And the same applies to the flower on Trichocereus bridgesii, which is another Bolivian Trichocereus.

Alright, now that we have this out of the way let me just say that the whole internet started having shitty discussions about the PC and what not. Most of the times, those guys just pick out one of the charasteristics of those plants and call  everything that resembles this Californian strain a PC…which is a really bad generalization. Imagine you were a botanist and field explorer that collected seeds in Bolivia. Now you find a cool regionality that produced a whole lot of seeds. Friedrich Ritter was this guy and collected so many seeds that he could populate the whole world with them…which he probably did. He sold his seeds through his Winter Samenlisten (which were written in three languages) and shipped them everywhere. Like literally. People grew them, raised those plants and planted them in their gardens. Some in California, some in Australia and some in other places of the world. That PC clone from California and the rest of the USA is probably just one cutting that was grown from those seeds. All the plants cloned from this one plant are genetically identical. But that doesn´t mean there can´t be more plants grown from the same seeds…which in fact are genetically diverse. You know, this whole site at the Rio Mizque is pretty big and as far as I know, Ritter collected loads of fruits. These days, most labels are lost but what´s left are the plants. And they are usually slapped with a short PC comment in the Facebook groups, though that is only a tiny piece of the puzzle.

And just to make sure this posting here is not misinterpreted. Are all the plants called PC the same? NO, absolutely not. Many people throw this word around and have absolutely no idea what they are talking about. Just one example. Here is a Bolivian San Pedro. As those are also related to Trichocereus bridgesii, they have a similar rib structure. Imagine them with long golden spines and you are good to go.

Well, okay. I want to come to and end but it´s important to make a very good point. YES, there are many San Pedros that are extremely similar to this clone. Not all of them are the same and I am sure there´s a fair amount that has absolutely nothing to do with this PC. But there IS a common clone in the USA (apart from the many other cultivars that are there, such as the three or four types of cereus monstrosa or all the other mutants that are currently flooding ebay. Nurseries are in the money business and they will replicate everything they can sell. And those Bolivian Trichos (and I count that PC in as well) are TAH (Tough as hell). You literally stick them in the ground and they grow. And that played a part in the fact that this PC Trichocereus strain is so common in some parts of the USA.

Alright, I want to sum this up. Everyone is a bit in the right here. The way this plant is discussed recently is out of control. And some people tend to forget that there is a huge number of plants that are really similar to this PC…and they are coming from the habitats. In Peru, there are similar plants and I just posted the examples that you can find in Bolivia as well. But that doesn´t mean that those plants were just invented by cookoo internet theoreticians. They were collected, sold and commercially cultivated. This plant does probably NOT come from Backeberg, which is another theory that was discussed heavily.

Trichocereus pallarensis / Echinopsis pallarensis

Trichocereus pallarensis / Echinopsis pallarensis 

Trichocereus pallarensis, also known as Echinopsis pallarensis, is an obscure species from North Peru that was discovered and described by Friedrich Ritter. It belongs into the same context that Trichocereus santaensis / Echinopsis santaensis belongs to.

Trichocereus pallarensis is a species that was described by Friedrich Ritter and listed in his WINTER catalogs starting in 1961! I do have most of the old Winter catalogs, but I unfortunately not the ones after 1960. But that´s not a problem as I have a whole lot of other information about Trichocereus pallarensis.

Ritter wrote about this species numerous times. He basically called this plant a “variety of Trichocereus pachanoi”, but described it as a new species just in case. Back then, it was common that botanists or taxonomists wrote new descriptions only based on minor differences, that would only be seen as a regional form by today´s standards.

Trichocereus pallarensis has 3 – 6 radial spines (15 – 50 mm long). Those are brown or honey colored and relatively thin compared with the ones on Trichocereus peruvianus and Trichocereus pachanoi. The middle spines are often missing or there is only one very strong and long middle spine. It is very similar to Tr. pachanoi in regards to the spination and most of the spines are only few millimeters long. The areoles are often very small and those packed areoles usually tend to miss the one middle spine as well.

Flowers of Trichocereus pallarensis:

Friedrich Ritter was not able to get a good description of the flower and I am working on one myself. The plant is very rare and if you happen to have a flowering sized one, please let me know so we can improve the flower description. With that said, it comes from the Pachanoi group and is probably almost identical to the one of Tr. pachanoi. The flower is definitely white, but I´d love to measure it some more.

Fruit of Echinopsis pallarensis: 

The fruit of Trichocereus pallarensis is 5 cm long and 4 cm thick. Covered with GRAY wool.
Seeds: The seeds of Trichocereus pallarensis are identical to the ones on other Tr. pachanoi types.

Origin/ Type locality of T.pallarensis:

Trichocereus pallarensis grows in Llancora, near Cajamarca. Near Pallar (that´s where the name comes from) and east of the cordillera Blanca. Department Ancash at 2.500 – 3.000 meters altitude.

Where to buy Trichocereus pallarensis seeds and plants:

Trichocereus pallarensis is very rare and only a few shops have them in stock. If you want to buy seeds of Trichocereus pallarensis, please join my seed list and I´ll let you know next time I have some. You can also get some fresh seeds from Sacredsucculents.com every now and then. They have a beautiful number of crosses that they produce every year. You might also be able to get some from Cactusaffinity and Misplant.

Trichocereus spachianus / Echinopsis spachiana

Trichocereus spachianus / Echinopsis spachiana 

Trichocereus spachianus aka Echinopsis spachiana is a columnar cactus that originates in Argentina.

Synonyms: Trichocereus shaferi, Trichocereus santiaguensis, Cereus spachianus, Echinocereus spachianus, Cereus santiaguensis, Echinopsis santiaguensis, Trichocereus manguinii, Trichocereus trichosus, Trichocereus spachianoides

If you want to buy seeds of Trichocereus spachianus, you can find some here:

The history of Trichocereus spachianus is very confusion and most taxonomists have their own opinion on how the plant originally came from and which subspecies or varieties are synonymous with it. The original plant described by Lemaire as Cereus spachianus in 1840 was said to originally come from Mexico and differed substantially from what we know as Trichocereus spachianus. Ten years later in 1850, Salm-Dyck described the Trichocereus spachianus as we know it today. Salm-Dycks plant is the modern Trichocereus spachianus. And according to his description, it has around 8 Ribs, a rib height of 10 mm and an areole distance of 20 mm.  Both descriptions lacked Flower descriptions, but there is what Lemaire´s plant looked like according to the description: 10-15 ribs, rib height of 5 mm and an areole distance of 6-10 mm.  The origin of Trichocereus spachianus is still not known, but there are some types in nature that are very similar to almost identical. Trichocereus santiaguensis grows around Santiago de Estero is the one that I suspected to be the original plant that was described as our modern Trichocereus spachianus. Besides, there is another population of a plant that was described as Trichocereus shaferi, which is probably synonymous too. Trichocereus shaferi grows in Jujuy near Leon. Another very similar Tricho grows in Bolivia and is called Trichocereus tenuispinus. That name is absolutely not valid and I am just mentioning it for the sake of completeness.

Trichocereus spachanius Description

Up to 2 meters tall and pupping from the base. Pups grow upwards and parallel to the main column. 10 – 15 Ribs and areoles approx. 1 centimeter apart. With yellow wool. 8-10 radial spines (0,6 bis 1 cm long) and 1 strong middle spine.

Flower: The flower of Trichocereus spachianus is white and up to 20 centimeters large. The Flowers don´t smell and the wild varieties are very unlike the ones in cultivation. Trichocereus spachianus is a night-flowering species, but the flowers stay open until late in the day.

Origin: Argentina (around Mendoza), in San Juan, La Rioja and San Luis. Jujuy (1500-1800 meters)

Trichocereus spachianus is a very tough and resistant cactus that can be used for all kinds of purposes, including as Grafting stock, fencing plant or for Hybrid cultivation. The flowers are very large and there are some amazing hybrids that involve Trichocereus spachianus. It is one of the best grafting stocks because it accepts many hosts. There are all kinds of plants that are synonymous with Trichocereus spachianus and none of the older species names like Trichocreus Santiaguensis or Trichocereus shaferi are valid today. Trichocereus spachianus is also called “Golden Torch” or “Golden Torch Cactus“.

Cultivation: Trichocereus spachianus is very frost resistant, but temperatures shouldnt go below -5° to -10° Celsius and it greatly depends on the general health of the plant and the dryness of the substrate if the plant suffers any damage. It has to be kept completely dry over winter and the bets temperature to overwinter it inside is at around 10° Celsius and with sufficient fresh air.

Seed & live cuttings sources: There are many sources for Trichocereus spachianus, including seed from various private sellers or commercial shops like Köhres, Misplant or SAB. Besides there are cuttings available from shops like Ebay and Amazon.

Varieties: There really aren´t that many accepted varieties of Trichocereus spachianus available. But there are a couple of regional varieties like Trichocereus shaferi, Trichocereus santiaguensis or Trichocereus spachianoides, which was a very similar plant that was probably synonymous and was collected and sold by Friedrich Ritter. The plant had the collection number FR980 and was collected in 1960/61.

Soil requirements: Trichocereus spachianus should be given a purely mineral soil mix that dries out very fast because it tends to suffer from rot if it is grown in seed with too much humous. You can use pumice, sand or any other mineral substrate. They like to get fertilizer on a regular basis. But I would recommend to water them only when it´s hot. No water on rainy or cold days and only water as soon as the soil has completely dried up! Trichocereus spachianus likes to be grown in partial shade but can also tolerate being grown in full sun. On the pics, you see that the plants are usually sown in full sun and they like it a lot. The flower is very large and beautiful, but the species needs to reach a certain size before it can flower.

BK10508.7 Trichocereus riomizquensis, Totora , Cochabamba, Bolivia 

Trichocereus riomizquensis BK10508.7 is a very cool Plant! that is obviously related to Trichocereus bridgesii.

Trichocereus riomizquensis is probably partially synonymous with Trichocereus bridgesii or belongs to Trichocereus bridgesii in a wider sense. The latter is not very surprising because both are from Bolivia and grow very close to each other.

Ritter gave CHYLLAS near the Rio Mizque in the province Campero as the type locality of Trichocereus riomizquensus, growing on rocky slopes.

Ritter assigned the FR/Winter seed code (after the name of his sister, who ran his seed business) FR856. After all these years, there are only very few plants of Ritter´s FR856 left which still have their original label intact and if thereanybody out there who grows a plant labeled Trichocereus riomizquensis FR856, please let me know and I will add them to the database! There were also seeds given away in the Sacred Succulents Field Trips and I´d love to see photos of the offspring as well.

If you are interested in Trichocereus riomizquensis, it can´t get any better than seeing the species in field expert Martin Cardenas´garden in Chochabamba. This plant is very unique, but also shows a close connection to Trichocereus bridgesii. I am sure if I was to take a look at the flowers now, I would see a flower that is extremely close to the flower of Trichocereus bridgesii. Buds, flowers and fruit bear white hairs, which can also be see on the notorious PC clone in the United States (which we suspect might be grown from Ritter´s Trichocereus riomizquensis seeds).

Trichocereus Crassiarboreus (NN)

Trichocereus Crassiarboreus (NN)

Trichocereus Crassiarboreus is a plant that was discovered by Friedrich Ritter in 1957. When he found flowering specimens in 1964, he moved the species to Weberbauerocereus. I am not a specialist on Weberbauerocereus but I trust Ritters Experience on that ID. The species was later publicized by Karel Knize under the name Weberbauerocereus Crassiarboreus but his description lacked substantial information and if he wouldnt have mentioned the typus location, there wouldnt have been a chance to find that species again. Besides, Knize added no pics, what makes it even more problematic. Ritter wrote numerous interesting pieces on this plant, including a complete description. Nonetheless, it seems that Knize´s descripion was accepted. Because of that, Trichocereus Crassiaboreus is now called Weberbauerocereus Cuzcoensis. That also explains why Trichocereus Crassiarboreus isnt offered in most commercial seed and plant lists. If you are lucky, you might be able to get some labeled as Weberbauerocereus Cuzcoensis though.

Buy seed or plants of Trichocereus Crassiarboreus: The seed seller köhres still has some seeds of Trichocereus Crassiarboreus/Weberbauerocereus Cuzcoensis in stock. I have no idea about the viability but when I ordered some around 4 years ago, they were still viable and looked very much like what is shown on those pics from K.Trout! They are amazing plants and everyone should consider himself lucky to grow them. I might also add a flower description and a general description of this plant in the near future. But because it is not a real Trichocereus, I will push that back until I am done with the rest of the site!
