Rosei 1- Trichocereus Peruvianus

Rosei 1 – Trichocereus Peruvianus

Both Rosei 1 and Rosei 2 are among the most popular clones in the Trichocereus grower 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 San Pedro. This name was mostly applied to the same plants that were later called “Trichocereus Macrogonus”. Which is another old name that is no longer in function. The name Trichocereus Rosei was never an officially described species and that´s why the Rosei 1 and Rosei 2 can only be called “commercial varieties” of simply a local form of Trichocereus Peruvianus. It´s not clear where the Rosei 1+ Rosei 2 seed came from but based on the fact that they both originated from the Fields collection, chances are that they grew out of the same seed bag.

Despite the fact that Rosei 1 and Rosei 2 are actually clones, you can find very similar Peruvianus specimens in nature. In particular, one of the types that occur in Matucana is very similar and chances are, that Rosei 1 and Rosei 2 originally came from that area too.

But because of the countless “planted” populations that can be found throughout the habitats, you can sometimes encounter similar plants at different locations too. So we probably won’t be able to find out where exactly they came from, but I´ll have a look at old cactus catalogues to see if there might be some old seed lists that include the collection sites.

According to people who visited the Fields family, those plants originally came from South America. But since that´s really a very big area, that´s not really helping. It is said thatRosei 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 am not entirely sure about what´s normal for this clone and what not.
