Euphorbia caput-medusae is a succulent euphorbia native to South Africa, growing in the Cape (Captown) region either in the rocks or in the sand on the west coast. It grows to around 30 cm in height and 2-3 m in circumference. The white flowers last from summer to early autumn. We grow two specimens in a greenhouse in the ground, while one grows on our rock. Often it's other jellyfish-headed euphorbias that are sold under this name.
