Cereus repandus

A tree-like columnar cactus up to about 10 m tall, from the hot, dry thorn scrub of the ABC islands and the Caribbean coast of Colombia and Venezuela. It grows in full sun, in constant heat, with little rain. Give it maximum light, warmth all year, and a dry spell in the early part of the year.

Where it grows wild

Coastal xerophytic scrub and cactus woodland on limestone, coral rubble and dry hills, exposed to steady trade winds. It is often the tallest plant in the scrub.

Mostly near sea level (median 31 m). The few records near 2,000 m are probably mislocated or come from dry inland valleys.
