This species of Trichocereus, which some want to lump in with Echinopsis, is from northern Argentina. An offsetting shrubby plant, this species is one of the species that was used to create many of the spectacular Trichocereus hybrids that have sprung up over the years. These plants have flowers that could be any number of different colors. We offer rooted cuttings of this species in one-gallon pots.
