Eulychnia breviflora

A tree-like, heavily branched columnar cactus, 2 to 3 m tall with long central spines, from the fog-fed coastal desert of northern Chile. It grows on coastal hills where rain almost never falls but a daily fog bank keeps the air cool and moist, so it wants full sun, mild temperatures, a gritty mix and very little water.
