Spiny succulent shrub to about 12-18 inches from southern Africa with waxy stems (thus the common name) and beautifully delicate white or yellowish flowers, often in profusion. The most common member of an uncommon group in cultivation. From the geranium family. Often and formerly called Sarcocaulon crassicaule. Like the ocotillo, these plants make two types of leaves: one with a persistent petiole that hardens and becomes a spine, and one without a petiole that emerges from the axil.

May be seasonally deciduous, but usually quite leafy in mild climates with regular water. This plant comes from areas with low rainfall, and it is quite drought tolerant. It responds to rainfall by leafing out and flowering. It does very well in dry winter rainfall (Mediterranean) climates.

Provide strong light and excellent drainage in cultivation. This is a well behaved container plant which responds nicely to pruning, often by branching. It is suitable for bonsai or cultivation in relatively small pots. Fertilized flowers will develop a sort of horn that breaks open when released at the base to reveal long seeds with long fine, feathery hairs attached. This plant is not self compatible.
