Of the about 30 species of the so-called medusoid group of Euphorbias, this is one of the biggest, sometimes reaching a metre or even more in diameter (including the branches).
It is very common over a large area stretching from the dry sandy plains east of Addo, northwards as far as Graaff Reinet and southwestwards towards the Baviaanskloof and the eastern border of the Little Karoo.
When the substrate is very hard, the main body is pushed above ground.
The name esculenta means “edible”, because the plants can be used as fodder in times of drought.
The flowers with their white woolly bracteoles give off a pleasantly sweet scent.
