Echinopsis uyupampensis

A shrubby columnar cactus with stems up to 1–2 m long and night-opening, pale yellow to white flowers. It grows on cliffs in the coastal mountains of southern Peru and far northern Chile. It lives almost without rain, getting moisture from coastal fog, so it needs full sun, mild temperatures, and very little water.
