Portulacaria afra, commonly known as the elephant bush, is a semi-evergreen succulent shrub native to the semi-arid regions of South Africa. It features reddish-brown woody stems and dense clusters of small, fleshy, rounded leaves that store moisture efficiently. Often mistaken for the traditional jade plant, it is widely appreciated in drought-tolerant landscaping, indoor container gardens, and the art of bonsai.
This hardy plant thrives in full sun and handles hot, dry environments with ease. Its growth rate is moderate during the active spring and summer months, while slowing noticeably during cool winter weather. Thanks to its remarkable ability to absorb carbon and conserve water, it makes a tough, dependable addition to any plant collection.
Caring for elephant bush is remarkably straightforward as long as you provide plenty of light and avoid overwatering. Saturated soil and low-light corners are the two most common culprits behind leaf loss and root problems. When potted in an open, gritty substrate and watered sparingly, it will live and flourish for decades.

Care
- Watering
- Water thoroughly only after the potting soil has dried out completely from top to bottom. During spring and summer, watering once every ten to fourteen days is usually plenty, reducing to once a month or less in winter. Insert a wooden skewer to the bottom of the pot to confirm dryness before adding water.
- Light
- Elephant bush demands abundant sunlight and thrives best with several hours of direct sun each day. If grown indoors, set it right beside your brightest south- or west-facing window to prevent stretching.
- Temperature
- The optimal temperature range is between 18°C and 28°C during the active growing season. It does not tolerate freezing conditions and must be protected when temperatures drop below 5°C.
- Soil
- Plant it in a gritty, fast-draining cactus and succulent mix amended with coarse sand, perlite, or pumice. Heavy, moisture-retaining potting soils will quickly lead to root decline.
- Fertilizer
- Feed with a balanced succulent fertilizer diluted to half strength once a month from early spring through late summer. Hold off on feeding entirely during the fall and winter rest period.
- Pruning
- Pinch back tender growing tips in spring to encourage dense, bushy growth and a sturdy branch structure. Use clean, sharp pruning shears to remove leggy or crossing branches as needed.
- Propagation
- Propagating elephant bush from stem cuttings is simple and highly successful during warm weather. Allow the cut ends to callus over for two to three days before inserting them into barely moist, well-draining soil.

Frequently asked questions
Why is my elephant bush dropping leaves?
Excessive watering and inadequate sunlight are the primary reasons for sudden leaf drop in elephant bush. Relocating the plant abruptly or exposing it to cold drafts can also trigger shedding. Check the soil moisture and ensure the plant receives several hours of bright, direct light.
How do you tell Portulacaria afra apart from a jade plant?
While both look similar, Portulacaria afra has much smaller leaves and distinctive reddish-purple stems. Its branches are also finer, more flexible, and ramified, making it far more pliable for styling as a bonsai.
Why are the leaves wrinkled and soft?
Wrinkled, shriveled leaves are a classic sign of dehydration due to prolonged dry soil. Give the root ball a thorough soaking so water drains freely from the base, and the leaves should plump back up within a day or two.
Can elephant bush live indoors permanently?
Yes, provided it is placed in an exceptionally bright spot with direct sunshine, such as an unshaded south-facing windowsill. In low light, the stems become weak, pale, and spindly while losing leaves rapidly.
