Tr. peruviana “Sharxx Blue”
Sharxx Blue is a short spined Trichocereus peruvianus clone that was named after SAB Member Sharxx. It originated from the well known DAWSONS cactus collection and was distributed and named by PD (another SAB member).
It probably is some kind of Trichocereus peruvianus from Matucana, very much like ICARO DNA, the Los Gentiles, Rosei or the many other Matucana Perus.
The plant is extremely blue and glaucous. Overall, Sharxx is one of my all-time favorite Trichocereus clones and it’s a very popular among Trichocereus breeders.
Tr. peruviana “Rosei 1”
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.
Peruvian Torch are relatively easily grown in the UK, especially due to the fact that they do not require massive amounts of sunlight. As most cacti grown in the UK, they are best grown in a greenhouse or conservatory (grow tents are also used for younger plants), South facing is a distinct advantage.
Watering from Spring (April) to the beginning of Autumn (End September). Depending on what kind of summer we get will depend on how frequently you need to water, but, less is better with cacti. During the winter months, little to no watering is required or the roots could rot (they do not like to be wet for long periods).
In warmer climates, you could go for a more nutrient-rich mixture (50% organic / 50% inorganic). But, in the UK, it is best to err more on the side of inorganic (60% – 70% inorganic) to ensure the pot is drained quickly.
