About

Portulacaria afra (known as elephant bush, porkbush, purslane tree, dwarf jade and spekboom in Afrikaans) is a small-leaved succulent plant found in South Africa. These succulents commonly have a reddish stem and green leaves, but a variegated cultivar is often seen in cultivation. They are simple to care for and make easy houseplants for a sunny location. In frost-free regions they may be used in outdoor landscaping.

How to grow it

In the wilds of South Africa, large plants do survive the winter frosts by growing dense enough to provide their own natural cover. Drought-tolerant and fire-resistant, it will endure desert sun and heat once established, which the jade plant will not. P. afra is a common landscape plant in Phoenix, Arizona, and southern California, growing in USDA plant hardiness zones 9–11. Cuttings root very easily in most potting media.

Where it grows

It is very widespread in the east of South Africa (as well as Eswatini). In this moist climate, it is relatively rare, and tends to favour dryer rocky outcrops and slopes.
