Guide

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

A hardy perennial from the dry, rocky slopes of the Mediterranean and Caucasus, with succulent blue-green foliage built to store water through long dry spells. Give it gritty, fast-draining soil and full sun, and water deeply only when the mix has dried out completely — wait until the top several inches are bone dry before watering again. It tolerates neglect far better than wet feet, which will rot the roots.

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.
