Portulacaria afra “Elephant Bush” is a large, bushing succulent with woody stems that can grow to incredible heights when given the proper time, nutrients, and growing conditions. It can also be used in hanging baskets to add “spiller.”
Elephant bush plant may get 2 - 6m tall in habitat where it is a favourite food of elephants. In the home interior, it is much more likely to remain just a few feet (around 1 m.) tall. The bush has thick succulent brown stems with small tender green leaves that resemble a diminutive jade plant. The home interior is an excellent place to grow elephant bush houseplants. Portulacaria care requires warm temperatures and bright light. After a dormant period in winter, the bush produces small pink flowers grouped in clusters at the ends of the branches.
