Guide

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

Euphorbia cyathophora is an annual or biennial herb ranging widely from the warm Americas into temperate North America, suited to open, sunny, well-drained ground. Give it bright light and a gritty, free-draining mix, and water only when the top inch or two of soil has dried out. Like other spurges it bleeds a milky latex when cut.

ToxicityAuthoritative · species

Toxic to cats & dogs & humans

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