One of the most beautiful of the Euphorbias from tropical East Africa, Euphorbia greenwayi grows on rocky hillslopes. From central Tanzania, this subspecies is larger than the typical, has square stems that are subtly marked in rich blue-green and pale-gray colors, has brownish-red spines, and the cyathia have red stamens. We offer rooted cuttings of this species in 4-inch pots.
