Echinopsis arboricola

An unusual tree-dwelling Echinopsis (often placed in Trichocereus) from the dry-season forests of southern Bolivia and Salta. Its slender stems start upright, then hang, rooting in the air, and it bears large white night-blooming flowers. Treat it as a warm, bright epiphytic cactus with a dry, cooler winter.

Where it grows wild

It grows on trees, and probably rocks, in seasonally dry foothill forest at the edge of the Andean Yungas, with aerial roots holding it to bark.

Literature gives 500–1000 m; the single climate site is at 1100 m.
