Trichocereus knuthianus (Echinopsis knuthiana)

Trichocereus knuthianus (Echinopsis knuthiana)

Trichocereus knuthianus is a plant that can be found in many parts of Peru. As a species, it is much more diverse than the clone that it is mostly reduced to and there are various forms that belong into the context of Trichocereus knuthianus.  In addition, there are intermediates with Trichocereus schoenii, Trichocereus tarmaensis and Trichocereus cuzcoensis.

Alternative name: Echinopsis knuthiana

Synonyms: Trichocereus knuthiana, Trichocereus knuthianus, Trichocereus cuzcoensis var. knuthianus, Cereus knuthianus, Azureocereus deflexispinus, Cereus deflexispinus, Trichocereus tarmaensis, Trichocereus peruvianus var. Tarma, Trichocereus crassiarboreus, Trichocereus schoenii, Echinopsis schoenii, Echinopsi tarmaensis (not all, but some of them clearly belong into the knuthianus context as well)

Though Trichocereus knuthianus is still considered a correct species with the name Echinopsis knuthiana, it is closely related to Trichocereus cuzcoensis and Trichocereus peruvianus. There was never any good DNA testing done to verify or question this, which is why it is on our short list of species that we´ll test for our upcoming book on the genus Trichocereus. In my opinion, it is a relative of Trichocereus cuzcoensis. We will find out how related exactly once we´ve ran some tests.

Trichocereus knuthianus was discovered and described by Curt Backeberg on the upper course of the Rio Marañon. The plant was named after Graf F.M.Knuth, who was Curt Backeberg´s co-author in the book KAKTUS ABC and a financier for some of his trips.

Most plants that are available on the open market were originally sourced from Friedrich Ritters Seed list. Ritter´s collection number of Trichocereus knuthianus was FR567, sometimes also labeled as Trichocereus knuthianus f. pachanoi or Trichocereus knuthianus FR 677! This strain can be found in collections throughout the World though it is most common in Australia.

Ritter wrote that it´s probably synonymous with Trichocereus tarmaensis and I agree to a certain degree. In addition, he shared the opinion that Trichocereus knuthianus is actually a variety of Trichocereus cuzcoensis, which is most likely correct as well. Trichocereus cuzcoensis only grows in Cusco, but its close relatives grow all over Peru, e.g. Trichocereus tarmaensis, Trichocereus schoenii, etc.

Curt Backeberg, on the other hand did absolutely not agree with Ritter´s attempt to nullify Backeberg´s species, as it would mean that his newly described “species” would´ve become invalid. Generally speaking, Friedrich Ritter knew that plant very well .

Mature plants of Echinopsis knuthiana in habitat tend to have that tree-like rounded log-shape that you can observe on Trichocereus cuzcoensis too. Most other Trichocereus species do not form such  a rounded and tree-like stump, which is another indicator for its genetic proximity to the Cuzcoensis complex.

Trichocereus knuthianus is very widespread and grows in Central Peru and some Departments that surround it.

Trichocereus glaucus – Echinopsis glauca

Trichocereus glaucus – Echinopsis glauca

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

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:

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 lamprochlorus / Echinopsis lamprochlora

Trichocereus lamprochlorus / Echinopsis lamprochlora

Trichocereus lamprochlorus is strange species that needs investigation. There are various species associated with Trichocereus lamprochlorus / Echinopsis lamprochlora, such as Trichocereus purpureopilosus and some forms of Trichocereus candicans that are considered to be synonymous with it. The species was merged into the genus Echinopsis during Friedrich & Rowley´s merger in 1974 and named Echinopsis lamprochlora (Lemaire).

Synonyms: Trichocereus lamprochlorus, Cereus lamprochlorus, Cereus nitens salm-dyk, Trichocereus candicans, Trichocereus purpureopilosus,

The situation around Trichocereus lamprochlorus is complicated because the original description of Cereus lamprochlorus (Lemaire) and the Trichocereus lamprochlorus that we know today are two different plants. It is unknown what kind of plant Lemaire was describing as Cereus lamprochlorus, but the description differs greatly from our modern Trichocereus lamprochlorus. One of the two plants associated with this name is a medium sized Trichocereus that pups very strongly from the base and grows in groups of many side-arms. The other one is a classical columnar cactus that grows upwards and tends to get a lot bigger than the other type. Both are totally different types of cacti, but were at some point, described as the same plant. The columnar growing type of this plant is the one that´s generally accepted as Trichocereus lamprochlorus today. Trichocereus lamprochlorus belongs to a very variable complex involving numerous closely related or visually similar species. Despite the fact that the two plants known as Trichocereus lamprochlorus are different types of cacti, they might still belong to the same group of plants and just be examples of different forms belonging to different populations. It is also possible that the columnar version is what´s shown on the photos below, and the smaller clumping cactus is the forum that was later described as Trichocereus purpureopilosus. Both of them are related and show visual similarities, but differ greatly in regards to their type of growth.

These pics were shot in Tiatako, Cochabamba, Bolivia. They show a regional form related to the type that we regard as Trichocereus lamprochlorus today. It has up to 15 ribs, strong spines, a reddish touch around the spines, a very bright green epidermis, 10-15 radial spines and 4 middle spines. The flower of the originally described plant was not know.

Britton & Rose already had problems with the two mixed up plants mentioned before and tried to get to the bottom of it. Without success. The other version of Trichocereus lamprochlorus was also described as “Trichocereus neolamprochlorus”. It is a plant that´s very similar and even related to  Trichocereus candicans. This plant stays relatively small, pups from the bottom, has a bright green epidermis that later changes to a sickly looking yellow color. The plants can get up to 10 centimeters in diameter, have between 8-12 ribsm, spines with a reddish touch. Its flowers are up to 25 centimeters large, white, covered with black wool. This type originally grows around Cordoba in Argentina and is a different type of cactus, one which is close to Trichocereus candicans. Due to the chaotic history, the nomenclaturic situation around these plants is convoluted.T

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-seeds-samen-north-peru Echinopsis pallarensis

trichocereus-pallarensis-seeds-samen-north-peru Echinopsis pallarensis 2Photo:

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 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 huanucoensis (Echinopsis)

Trichocereus huanucoensis (Echinopsis)

Trichocereus huanucoensis goes back to a nursery owner called Harry Johnson senior, who brought this plant into the USA in the 1950s. Unlike popular belief, Trichocereus huanucoensis is NOT an official species. There is no official description and very little information about the plant. According to Herbarium pieces, its place of origin is Huanuco. It is a beautiful town directly beside Chavin de Huantar and the plants that can be found there are Trichocereus santaensis and intermediate forms between Trichocereus santaensis and Trichocereus pachanoi. The same applies to Trichocereus huanucoensis too. It is fairly typical of Backeberg´s species Trichocereus santaensis and the place of origin underlines that. If you want to see similar plants, check out the posting about Chavin de Huantar.

Trichocereus huanucoensis Echinopsis Misplant

Trichocereus huanucoensis has very wide ribs, which give it a similar look to Trichocereus santaensis and Trichocereus bridgesii. The original site where Johnson collected his seeds is unknown, but the plants grown from them are common to be found in some parts of the USA. In California, quite a few larger plants were planted outside. Apart from its occurrence in cactus nurseries and collected in the USA, it is very rare in Europe. This underlines the suspicion that Mr. Johnson was indeed the source and distributed this plant among his friends and customers.

Trichocereus huanucoensis tends to be extremely fat and has a very bloated look. Its spine length is extremely variable and the specimens can have no spines or long spines but it usually has very few spines per areole. The spines are usually golden, but lack a swollen spine base. This is a key similarity to the plants from Chavin de Huantar as well.

Though the obvious lack of a description, it is a very attractive plant that deserves to be propagated. It is commercially available from Sacred Succulents or Misplant but it is still a rare plant.

One specimen of Trichocereus huanucoensis is also growing in the Huntington Botanical Garden in California. The specimen that Sacred Succulents use for their Huanucoensis crosses was originally from Ed Gay, who was a close friend of Johnson & Huntington. Some people tend to believe that Trichocereus huanucoensis is a Bridgesii relative, but the flower morphology pretty much rules that out right away. Its flowers and flower buds are typical for a Peruvian San Pedro, especially T. santaensis.

There is a variety of this plant on the market labeled H80361, which probably originated from Johnson also. There might have been the chance to find out more about the origin of the plant in the Huntington Botanical Garden but unfortunately, they do not have any info on where some of their older plants came from. At some point, their ID cards were stolen or lost, what makes it more difficult to find more information on the plant´s origin other than that it came from Huanuco.

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

This is a purely informational post and database entry. We do not sell seeds or plants of this species. 

Photo Trichocereus pachanoi Echinopsis pachanoi cactus

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 flower, 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: 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: 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.

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 Manguinii aka Trichocereus WK

Trichocereus Manguinii aka Trichocereus WK

Trichocereus Manguinii366 aa

Hi Guys, another cactus from the ancient times. Trichocereus Manguinii Backeberg, which can also be found throughout Australia under the name Trichocereus WK. I have absolutely no idea what WK stands for but the name Trichocereus Manguinii goes back to Backeberg, who tried to describe it as a species. Sometimes, we come across plants in our Trichocereus Facebook group. Most of the plants we encountered were probably brought into circulation by Backeberg himself or Friedrich Ritter in the early days of worlwide cactus trade.

The plant looks like a mix between a Trichocereus Terscheckii and Trichocereus Schickendantzii. It is very similar to Trichocereus Schickendantzii but it grows more columnar, is thicker and has red flower bulbs instead of green ones on Trichocereus Schickendantzii. The color of the epidermis is usually very dark green.

Description: Upright growing columnar cactus that usually pups very strongly from the base. The plant tends to form a lot of shoots and can form small group of plants very fast. Trichocereus Manguinii reaches a size of up to 120 centimeters and a maximum diameter of up to 15 centimeters. It has 18-21 ribs. The body of Trichocereus Manguinii has a dark green body, that differentiates it from similar lookalikes. Trichocereus Shaferi is similar for example, but it isnt as green as this one and has a lot less ribs.
The areoles are somewhat sunken in and usually have a dominant white fluff covering them. It has 10-12 radial spines and up to 4 middle spines than can get up to 0,5 centimeters long.

Flowers: The flowers are usually white and reddish/brown sepals that are covered with scales. The flowers can get up to 15 centimeters long and are very massive, compared to Trichocereus Schickendantzii. Trichocereus Manguinii forms a lot of flowers that are coming from all over the plant, including from the areoles.

Origin: Probably Argentina. But there was great confusion surrounding this plant because it was mostly known as a collection plant. One very large plant was located in the collection of Mr. Rivierre but I have no idea what happened to it. This plant is really rare today and will probably not come labeled under the “correct” name. The name was not accepted, which is why I chose the quotation marks. Trichocereus Manguinii is now integrated into Trichocereus Schickendantzii, though this large monster of  a cactus is definitely different from what I know as Tr. Schickendantzii. But since the plant is extremely rare, it´s probably not really high on any modern Taxonomist´s “To-Do” list to re-classify it.

As there are many Trichos from around the time of Backeberg and Ritter growing in Australia, this plant can be found sometimes over there. I´ve seen two of them recently that were posted in our Trichocereus group and I really hope to get some more pics and/or seeds in the future. It´s an amazing plant that usually comes labeled “Trichocereus WK”. If someone has an idea what it might mean, please let me know.

Where to buy seeds or plants of Trichocereus Manguinii? Well, this plant is currently not available anywhere in the world. I am trying to get some seeds and if I should ever locate a source, I´ll let you know.

Trichocereus Poco (Echinopsis Tarijensis)

Trichocereus Poco (Echinopsis Tarijensis ssp. tarijensis)

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

Taxonomic Background: These days, Trichocereus Poco has been integrated into the species Echinopsis Tarijensis aka Trichocereus Tarijensis though there are minor differences between the two. However, the fact that the species is extremely variable makes this a somewhat acceptable decision. Backeberg tried to keep it separate from Tarijensis and used the name “Helianthocereus poco” for the tarijensis-type Trichocerei from the southern highlands of Bolivia. But his description did not say anything the mature form of this species, which looks totally different to it´s juvenile forms.

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

Ribs: 20-32.

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

Origin: Trichocereus Poco grows in Bolivia and Argentina.

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

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

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