Euphorbia stellata grows amongst grass and pebbles in the Eastern Cape in the districts of Port Elizabeth, Albany and Peddie. The root and stem form one large subterranean tuber. The branches are prostrate with paired spines on the margins.
Euphorbia stellata prefers a well drained soil. In habitat the plants often grow fully exposed. In very hot areas the plants may need some protection from the sun.
