Portulacaria
Family: Portulacaceae
Common Name: Elephant Bush
This single-species genus from South Africa is not too well known but will appeal to succulent enthusiasts. A succulent, evergreen, many-branched shrub, in its native habitat it is often used as a fodder plant.
Species
P. afra, to 2 m (6 ft) high, has a thick, fleshy, silvery brown trunk. The branches are horizontally arranged, rather brittle, and sometimes twisted. The small, fleshy, round leaves are glossy green and flat. The infrequent flowers are borne in bundles on a thick stem and are a pretty salmon pink, colouring the whole bush. The cultivar 'Foliisvariegatus' has leaves variegated with yellow.
Cultivation
P. afra will grow just about any-where. It makes an attractive pot plant or bonsai specimen and does well in the garden, provided it receives protection from frost. In climates which are prone to frost, grow it in a warm greenhouse or conservatory. In its hot, dry habitat, it produces clusters of tiny, pink flowers, followed by small, pinkish berries. However, it is said that the plant will flower only when it is old and has been left completely dry for several weeks, or even months, through the winter. Its flowers should appear in summer. Propagation may be from seed but is very easy from cuttings at almost any time of year.
