Portulacaria afra Botanical Information
Name Derivation: The name Portulacaria is composed of Portulaca + aria suggesting a similarity to the genus Portulaca. The word afra is in reference to the fact that the plant occurs in Africa.
Morphology: Succulent shrub or small tree, up to 5 m high. Leaves fleshy, obovate, sessile. Small flowers produced in profusion, in dense sprays at ends of short lateral branchlets. Flowers pink to mauve. They are a rich source of nectar for many insects, which in-turn attracts insectivorous birds.
Habitat: Dry rocky slopes and hillsides.
Growing Portulacaria afra: The Porkbush is easily propagated from cuttings, the seed is not often available. Cuttings or truncheons strike root easily and can even be planted directly into the ground where they are to be grown. Alternatively, cuttings can be taken in the normal manner and allowed to dry out for a day or two in a cool, dry place and then planted in washed river sand. Keep them in a warm shady position until they are rooted and ready to be planted out. Cuttings root quickly and can usually be planted out after four to six weeks.
