Guide

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

Euphorbia canariensis is a columnar succulent shrub native to the arid, sun-exposed slopes of the Canary Islands, so it stores water in its stems and wants gritty, fast-draining mix and strong direct light. Water deeply but infrequently, only once the soil has dried out completely throughout the pot; when in doubt, wait longer, as standing moisture rots the roots. It tolerates dry indoor air well and needs no added humidity.

ToxicityAuthoritative · species

Toxic to cats & dogs & humans

Euphorbiaceae produce a caustic, 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.
