Trichocereus grandiflorus / rowleyi (Echinopsis grandiflora) – Awesome!

T.grandiflorus rowleyi grandiflora echinopsis weird flower_6

Trichocereus grandiflorus is a cactus from the genus Trichocereus. Its status is highly questionable as a correct species and the opinions are as varied as the names it carried. Joel Lodé has listed Trichocereus grandiflorus as Trichocereus rowleyi right now, while Anderson listed it as a synonym of Echinopsis huascha in his Cactus Lexicon. Please note that some people also refer to this plant as Echinopsis grandiflora, but this name is also used by Echinopsis eyriesii v. grandiflora and the older name has priority.

Synonyms of Trichocereus grandiflorus:

Lobivia grandiflora, Lobivia grandiflorus, Helianthocereus grandiflora, Helianthocereus grandiflorus, Helianthocereus huascha, Trichocereus rowleyi, Echinopsis huascha

Trichocereus grandiflorus was moved around between the genera  a lot in the past. It is genetically close to both Lobivia and Soehrensia, which is why it was sometimes included there. Friedrich et al. listed it as Echinopsis grandiflora. Anderson then listed it as a synonym to Echinopsis calochlora in his CACTUS LEXICON. Joel Lodé lists it as Trichocereus rowleyi. Schlumpberger lists it as Soehrensia grandiflora (Schlumpberger).

T.grandiflorus Flower:

The flowers of Trichocereus grandiflorus are often red and/or show various variations of red flowers. There are many hybrids, which is why the flower color is relatively unrelaible. There also are versions of flowers that are white in color and between 15-25 Centimeters in size. The tube is usually very hairy, but there are countless hybrids with all kinds of flower colors available on the open market.

Origin of Trichocereus grandiflorus:

Argentina, especially around Catamarca. The original description refers to a plant from a private collection and it is suspected that Trichocereus grandiflorus is extremely close to Trichocereus huascha and might even be part of this species.

The original description as Lobivia grandiflora came from Britton & Rose. Because of that, the plant was labeled as a Lobivia in most classic cactus literature. In addition, the title “Grandiflorus”, which roughly means “Large Flower” makes a lot of sense because most Lobivias usually have smaller flowers. The large flower size for a Lobivia shows that it is not a very normal Lobivia either. The collector Fric, who labeled it Chamaecereus giganteus (same principle because most Chamaecereus are tiny Lobivia), originally introduced the plant into the market, but since it was so different from Chamaecereus, this did not last long. Backeberg wanted to put it in his own problematic Genus Helianthocereus due to the diurnal flowers, but this flawed system was not adapted. Eventually, the plant ended up in Trichocereus, where it was until the restructuring made by Friedrich et al.

Cultivation of Trichocereus rowleyi (ex GF):

Trichocereus grandiflorus is a very hardy plant that can grow a lot during just one growing season if watered accordingly. The plant is able to tolerate some light frost but I would not recommend trying it out to the limit. I keep them at around 10° Celsius during the wintertime in a bright and well-ventilated room. I do not water them during the wintertime and only start watering again in March.

Buy Trichocereus grandiflorus / Seeds or Plants:

This plant is available every now on then on marketplace sites like Ebay or Amazon. In addition, many growers use it to produce hybrids. The Californian nursery Sacred Succulents has some colored Grandiflora hybrids and they sell seed every now an then. You can also try to make a post at our Trichocereus group at https://facebook.com/groups/trichocereus   because there are some growers there who give some away every now and then.

Trichocereus grandiflorus also shows similarities to Trichocereus schickendantzii and some even consider them close relatives. It´s sometimes difficult to keep the two apart and growers or collectors mix them up all the time. The same applies to Trichocereus huascha, which differs from Trichocereus grandiflorus through its spination.

Due to the fact that there are so many misidentified Trichocereus grandiflorus, or plants that are identified as Trichocereus huascha but are actually GF, a large part of the photos that can be seen online show something else. This whole confusion is worst with small and juvenile plants. Trichocereus grandiflorus is MULTI-Ribbed and grows columnar. Its higher rib count and the strange pupping behavior in combination with shorter spines than T. huascha and its typical pupping style at the base make it possible to identify it reliably though. The pups almost look like little balls on the base of the plant while Trichocereus schickendanzii forms large clusters that can get up to 1-2 meters wide. The problem with Trichocereus grandiflorus is that the original description was written after a collection plant, which may or may not have already been a hybrid of Trichocereus huascha.

Before we get to the pics, let me first take the time to say thank you to Prier, who donated those amazing pics. Thanks Prier!

Note the differences in regards to the flower. White versions of Trichocereus grandiflorus are almost always misidentified Trichocereus schickendantzii, Trichocereus shaferi, or true hybrids involving T. huascha or T. grandiflorus that resulted in a white flower.

Trichocereus huascha (Echinopsis huascha)

Trichocereus huascha Echinopsis huascha Lobivia Helianthocereus Delia 2

Trichocereus huascha, also known as Echinopsis huascha, is an Argentinian Trichocereus species that looks very similar to Trichocereus spachianus, Trichocereus grandiflorus, Trichocereus shaferi and Trichocereus schickendantzii. However, there are important differences to distinguish them.

Trichocereus huascha has had a long history with many name changes due to its unique position between Trichocereus, Lobivia and Echinopsis. Friedrich & Rowley renamed it to Echinopsis huascha in 1974 but their actions weren´t really embraced with love.

I have some fresh seeds of Echinopsis huascha. You can get them here:

Synonyms: Lobivia huascha, Helianthocereus huascha, Trichocereus huascha, Echinopsis huascha, Soehrensia huascha, Cereus huascha, Cereus huascha variety flaviflorus, Cereus huascha var. rubriflorus, Lobivia purpureominata, Trichocereus andalgalensis, Echinopsis andalgalensis, Lobivia andalgalensis, Trichocereus grandiflorus, Echinopsis grandiflora,

Described varieties of T.huascha:

Trichocereus huascha v. robustior or robusta

Trichocereus huascha v. pecheterianus

Trichocereus huascha v. rubriflorus 

Trichocereus huascha v. auricolor 

The list of names that Trichocereus huascha already had does not fit on one page, so I will only keep the most important ones. Many varieties of this species were actually labeled Lobivia, Cereus or even Chamaecereus and it´s very difficult to differentiate the plant from similar plants like Trichocereus schickendantzii, Trichocereus spachianus or Trichocereus grandiflorus.

Echinopsis huascha usually grows in small, clumping groups that reach up to 1,1 meters in height. It usually pups abundantly and can grow upwards like a columnar cactus or creeping. The pups can get up to 5-6 centimeters in diameter and has up to 15 ribs as a mature plant. The areoles are between 1 cm and 1,5 centimeters apart from each other. There are yellow colored and needle-like spines on each areole. Trichocereus huascha has 10-12 radial spines that are up to 2 centimeters long. The flower color is absolutely variable; also because there are SO many natural and commercial hybrids. This plant is used extensively in Trichocereus hybrid culture and many hybrids that are floating around on the market cant fully be id´d because the offspring can sometimes look very different from the parental generation. The plant flowers from the apex, through the areoles and the flower color can be yellow, red or orange. You can keep it apart from plants like Trichocereus schickendantzii by the color of the flower (Schickendantzii has white flowers) and the thinner growth of E. huascha. The flowers are 6-8 centimeters in diameter and the species is usually dayflowering! They also are sometimes self-sterile, while other forms are self-fertile. You usually need two plants to get seed, but T.huascha hybridizes so easily in nature that there are some plants that form fruit without being pollinated! There are constant arguments about its synonymy with Trichocereus andalgalensis and at the moment, I consider them synonymous. Trichocereus andalgalensis was described as a red flowering variety of T. huascha (T. huascha v.rubriflorus), but since there are also yellow flowering T. andalgalensis at the original site, this is not really a species that I consider correct.

Origin of Trichocereus huascha:

Argentina. Very widely distributed and can be found almost everywhere around Catamarca & La Rioja. The plant grows at 900-2000 meters altitude.

Trichocereus schickendantzii (Echinopsis schickendantzii)

Trichocereus schickendantzii (Echinopsis) was originally described by Britton & Rose in their book THE CACTACEAE, which was published in 1920. The plants grow in large clusters, in which they are pupping abundantly from the base! They can get up to 40-50 Centimeters, though they usually stay around 30. They have a diameter of 5-8 centimeters and a very healthy, green colored epidermis.

Ribs: They usually have between 13-18 ribs that are between 0,5 and 1 cm high. The spines are yellow and between 1-2 cm long. It has 7-10 radial spines and 2-7 middle spines.

Flowers of Trichocereus schickendantzii:

The flowers are white and can get between 20-25 centimeters long with green tube and sepals and black heairs/white petals

Origin: Argentina, Tucuman

Cultivation: Trichocereus Schickendantzii is a very popular grafting stock and a hardy cactus. They can take a lot of water during the hot season, but should not get wet “feet”. The average temperature should be around 10° celsius during the winter time. In summer, they can be grown in full sun but usually prefer a spot with partial shade. They should be hardy down to at least 0° celsius (and maybe even more) but I would not feel comfortable testing the boundaries. In a European country like Germany or France, they won´t survive the winter if kept outside. Some growers in the south of france reported that they tried to overwinter it with some rain protection but I am not sure if it worked. They should be totally dry during the winter and only be watered from April to Oktober.

Seeds of Echinopsis schickendantzii

There are a couple of growers who offer seed every now and then on our Trichocereus Group on Facebook. The plant is also sometimes in stock in the SAB Shop. Apart from that, you might also be lucky to get it from Seed suppliers like Köhres or Kakteen Haage but I have no idea how viable their seed is. In case of fresh seed, they are very easy to grow from seed. They prefer a mineralic soil type.

At a very young age, they look very much like Trichocereus Grandiflorus. However, they don´t get as big as Grandiflorus and have a different pupping behaviour. But generally speaking, they can be very similar and many pics labeled as Schickendantzii, including some on that page may or may not belong to Trichocereus Grandiflorus. The pic that is underlined with cs California shows a very typical Schickendantzii, which is substantially smaller than the ones on the other pics. But since there also are hybrids, it´s pretty tough to keep them seperate from the more columnar growing Grandifloras.

Thank you very much to everyone who donated the Pictures! I greatly appreciate it!
