Euphorbia

RHS Genus Guide

Euphorbias are among the most useful of garden and house plants. Some make imposing domes of foliage while others create more modest but good ground cover. In addition to the hardworking foliage, their flowers, often a zingy acid yellow, are usually long-lasting. Botanically related are the tender, succulent euphorbias and houseplants that hail from arid or tropical areas of the world.
