Guide

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

A succulent shrub from arid northwest Mexico, Euphorbia lomelii stores water in its stems and wants gritty, fast-draining mix with strong light. Water deeply but infrequently, only once the soil has dried out completely through to the bottom of the pot. It rots quickly if left sitting in moisture, so err toward keeping it dry.

ToxicityAuthoritative · species

Toxic to cats & dogs & humans

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