This species, from the Ruaha River Gorge, Tanzania, is one of the most beautiful of the Euphorbias from tropical East Africa. It has square stems that are brilliantly marked in rich blue-green and pale-gray colors. The spines are reddish, and the cyathia have red stamens. The overall effect is an extremely beautiful container plant. These plants have a little wider stems than the typical species. We offer rooted cuttings of this species in 5-inch pots.
