Guide

The species-level account. Cultivar pages build on this and say where they differ.

A deciduous shrub or small tree native to seasonally dry forests from Mexico through Central America to Colombia, accustomed to strong light and a pronounced dry season. Give it the brightest spot you have and let the top two inches of mix dry out before watering deeply, easing off further in cool or dormant months. It tolerates ordinary household humidity and resents staying wet.

ToxicityAuthoritative · species

Toxic to cats & dogs & humans

Euphorbiaceae produce an irritant milky latex that can harm skin, eyes, and mucous membranes if ingested. This is where toxicity lives: every cultivar of this species inherits it and none can override it.
