Echinopsis pachanoi (San Pedro Cactus)

(Cereus pachanoi, Trichocereus pachanoi)

This fast-growing cactus is native to the Andes in South America (Ecuador and Peru), at elevations of 2,000–3,000 m above sea level. The species has not naturalised in Australia, but it has naturalised in Colombia and Galapagos islands. There is no evidence of invasive behaviour anywhere in the world. Reproduction is via both seed and vegetative means. The fleshy fruit is likely dispersed by birds and other animals. A closely related species, Echinopsis spachiana, has been recorded as invasive in South Africa. San Pedro cactus contains mescaline, a psychedelic alkaloid. Whilst it is legal in NSW to cultivate this cactus for ornamental purposes, it cannot be cultivated for consumption.
