Echinopsis macrogona

Peruvian torch cactus (Trichocereus macrogonus, including T. peruvianus) is a branching columnar cactus 2.5–5 m tall with six to eight ribs, native to the high inter-Andean valleys of Peru and perhaps north-west Bolivia. It wants strong sun, a dry season, cool nights and mineral soil, and is widely cultivated.

Where it grows wild

Dry rocky slopes and scrub of inter-Andean valleys; widely planted, so many records are cultivated.

The wild habitat is mainly 2,000–3,500 m; recorded elevations go down to 68 m, which is a coastal Lima record and probably a planted specimen.
