Guide

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

Euphorbia glauca is a member of the spurge family, a group whose succulent and semi-succulent members store water and resent staying wet. Plant it in gritty, free-draining mix and let the top several centimetres of soil dry fully before watering again. Give it a bright spot, some direct sun if available, and err toward keeping it too dry rather than too wet.

ToxicityAuthoritative · species

Toxic to cats & dogs & humans

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