Elephant Bush

Portulacaria afra,Dwarf Jade, Spekboom, Porkbush

Elephant Bush is a resilient, woody succulent native to South Africa, where it serves as an important food source for elephants and other wildlife. It features small, round, fleshy green leaves on reddish-brown, often arching stems. It naturally grows into a dense shrub, but is often grown indoors as a houseplant, bonsai, or trailing plant. It does produce tiny pinkish-white flowers in clusters, but these are extremely rare when grown indoors. Popular cultivated varieties include the standard green form, 'Variegata', and 'Prostrata'.

Care Guide

LIGHT

  • Requires bright light, including direct sun, to maintain compact, healthy growth and prevent leaf drop.
  • Place in a South or West-facing window for best results.
  • In low light, the stems become weak and leggy, and the leaves will drop easily.

WATER

  • As a succulent, it is very drought-tolerant.
  • Water thoroughly and deeply, then allow the soil to dry out completely before watering again.
  • Overwatering is the fastest way to kill this plant, causing root rot and mushy stems.
  • Reduce watering significantly during the winter when the plant is dormant.

SOIL

  • Needs an extremely fast-draining, gritty soil mix.
  • Use a mix formulated for cacti and succulents, with a high percentage of perlite, pumice, or coarse sand.
  • Avoid heavy, water-retaining soils.

GROWTH HABIT

  • Ideal conditions: Full sun, warm temperatures (65-80F), and low humidity.
  • Growth rate & size: Growth rate is moderate to fast under full sun. It grows as a woody shrub, usually 1-3 feet tall indoors, easily shaped by pruning.

PROPAGATING

  • Propagates extremely easily from stem cuttings.
  • Cut a 3-5 inch segment of stem, allow the cut end to callus (dry) for a few days, and then plant it in dry succulent soil.
  • Water sparingly only after the cutting is established (a few weeks).

PRUNING

  • Pruning is essential for shaping, especially when grown as a bonsai.
  • Can be pruned hard at any time during the growing season to encourage bushier growth.
  • Remove leggy or weak stems to maintain a compact shape.

REPOTTING

  • Repot when the plant is root-bound, typically every 2-3 years.
  • Repot in spring or early summer.
  • Use a pot only slightly larger than the current one to maintain control over soil moisture.

FERTILIZING

  • Feed lightly during the spring and summer growing season (once a month).
  • Use a liquid fertilizer formulated for cacti and succulents, diluted to half strength.
  • Do not fertilize in fall or winter.

FLOWERING

  • Produces tiny pinkish-white flowers in small clusters at the tips of the branches.
  • Extremely rare when grown as a houseplant; usually only occurs on mature, large outdoor specimens receiving maximum sun.

TOXICITY

  • Considered non-toxic to humans, but the ASPCA lists it as toxic to cats and dogs, causing mild digestive upset.

PRO TIPS

  • If the leaves start to wrinkle or shrivel, the plant is underwatered and needs soaking.
  • It is a fantastic plant for bonsai training due to its small leaves and woody structure.
  • If moving outdoors for summer, transition slowly to prevent the leaves from burning.

Variability in Care

Most varieties of this plant follow the standard care above, but some require adjustments.

Variegated Elephant Bush

Examples: Portulacaria afra 'Variegata'

  • Features white or creamy-yellow variegation on the leaves and stems.
  • Requires brighter light than the green form to maintain the crisp variegation.
  • Is often slower-growing and more sensitive to overwatering due to less chlorophyll.

Dwarf and Miniature Cultivars

Examples: Portulacaria afra 'Aurea', Portulacaria afra 'Prostrata'

  • Dwarf types are prized for their compact leaf structure and smaller size.
  • Trailing types ('Prostrata') should be grown in hanging baskets to allow the stems to cascade.
  • Both need small containers and less frequent watering than large, vigorous plants.

Rainbow Bush

Examples: Portulacaria afra 'Rainbow'

  • The leaves display shades of red, green, and cream, often with a pink tint.
  • The colorful tint is only maintained under intense, bright light conditions.
  • Colors will fade dramatically and leaves will turn mostly green in shade.
