Rosei 2 x Sharxx Blue

T. Peruvianus x T. Peruvianus 

Trichocereus ‘Rosei 2’ was part of the legendary Australian Fields collection. Both Trichocereus rosei clones were brought to Australia by Harry Blossfeld, who was one of the first importers of cacti.

Sharxx Blue is a short spined 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
