Euphorbia triangularis

A tree-forming succulent euphorbia with three-angled, candelabra-like branches, native to the subtropical thicket and coastal bush of the Eastern Cape, KwaZulu-Natal, Eswatini and southern Mozambique. In the wild it grows in strong sun with warm, fairly humid summers and a mild, drier winter; in cultivation it wants maximum light, a free-draining mix and drier, cooler winters.

Where it grows wild

Grows in dense valley thicket, coastal bush and on rocky slopes and river valleys, often emerging above the surrounding scrub. Most wild records cluster in the Eastern Cape thicket between Port Elizabeth and East London.

Mostly lowland, from near sea level to a few hundred metres; the measured sites lie at 30-165 m.
