Othonna euphorbioides is a remarkable caudiciforms species with the habit of a miniature spiny succulent shrub, broader than tall barely 10-15(-30) cm tall. It is the most cactus-like of all succulent Compositae (near Senecio) forming spiny masses of succulent stems seemingly remote from the better known Othonnas. This plant acquired its name by resembling many of the spiny succulent euphorbias.
O. euphorbioides is one of the easier species to cultivate. They must be grown very hard in the nursery as close to the natural conditions as possible. This ensures that they keep their compact habit.
