(Baja California - Zone 11b) on Mar 9, 2019 4:03 PM concerning plant:
Low, branching South African succulent Euphorbia with characteristic star-shaped spines (thus the name) which are actually persistent peduncles, the bases on which cyathia appear. Some peduncles may be sterile, and some flowers lack the characteristic peduncle. Newly formed spines are pinkish red, fading to gray. Cyathia are small, with wool and green glands bearing marginal cilia. Stems are pale green, with marked tubercles, branching at the base. Plants are dioecious (separate male and female individuals).
Widespread range in habitat across South Africa, though not common there, and not particularly common in cultivation. May be found in older publications as E. stellaespina. Well behaved in container culture, though not particularly fast growing.
