Portulacaria afra

Portulacaria afra, or Elephant Bush, is native to South Africa. In nature they will reach 12 feet (4 m) in height with an equal spread. In containers, they will stay much smaller and their size is easily controlled with selective pruning and pot size. The attractive reddish-brown stems with dark green inch (2 cm) leaves make a great bonsai plant with very little care involved. They are hardy in USDA zones 10-11 where they are used as hedges.

Blooming Time: In the spring, they have clusters of small, inconspicuous pink flowers.

Culture: Portulacaria afra do best in full sun with a well-drained soil mix. In the greenhouse, we use a soil mix consisting of 2 parts sand to 1 part loam, with small gravel added to increase drainage. During the summer months, these plants are watered regularly, but we allow the soil to dry before watering again. During this period they are fertilized twice using a balanced fertilizer. Care should be taken during the winter months not to over water them. During this period, one should water only enough to keep the leaves from shriveling.

Propagation: Portulacaria afra is easily propagated by cuttings in April- May.

Portulacaria afra was featured as Plant of the Week June 6-12, 2003.
