Guide

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

Euphorbia trigona is a succulent shrub that stores water in its upright, triangular green stems, so it tolerates drought far better than standing wet. Give it bright light with some direct sun, plant it in gritty, fast-draining mix, and water only when the soil has dried out completely to the bottom of the pot. In lower light or cooler conditions, lean toward the longer interval.

ToxicityAuthoritative · species

Toxic to cats & dogs & humans

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