Euphorbia triangularis is the most common tree Euphorbia in the Eastern Cape Province. Their distribution extents from the Uitenhage district northwards into KwaZulu-Natal.
The branches of Euphorbia triangularis can be 3, 4 or 5-angled. The 3-angled form occurs more in the Eastern Cape and the 5-angled form in KwaZulu-Natal. The branches are segmented and deciduous, leaving older trees with a naked trunk and a whorl of branches at the top.
The trees can grow up to 18 m high.
The cultivation of Euphorbia triangularis is quite easy. The plants can withstand a considerable amount of water as long as the soil has good drainage. The plants can be propagated from seed or cuttings.
