A Miniature Jade Look-Alike
Elephant bush, Portulacaria afra, is a succulent shrub often mistaken for a small jade plant, though the two are not related. It is grown both as a modest houseplant and, in its native range, as a much larger landscape shrub, and it has drawn recent attention for how efficiently it draws carbon from the air.

A South African Native
This plant comes from South Africa, where it grows wild as a shrub reaching up to fifteen feet, its foliage grazed by elephants, which is how it earned its common name. The leaves are also eaten by people, offering a sour flavor often used in salads. Botanically it sits in the Didieraceae family under the genus Portulacaria, though it is sometimes still associated with the purslane family.

Sun, Sparing Water, Warmth
Give elephant bush bright but indirect light, with tolerance for full sun and a preference for gentler morning rays over harsh afternoon exposure. Water only once the soil has dried out, roughly weekly in the hottest months and tapering to monthly over winter, always in a very well-drained, gritty mix. It also appreciates more humidity than most succulents, around fifty percent, and steady warmth between 65 and 80°F, with feeding kept light: a diluted, low-nitrogen fertilizer once a month in spring and fall, a bit more often in summer, and none in winter.

Easy From Stem Cuttings
Stem cuttings taken in spring or summer, from a healthy stem clipped just below a node and left to callus for a few days before planting, are the quickest and most reliable way to propagate this plant. Leaf cuttings work too, treated the same way, but they take longer and root less reliably than stems. The RHS route is similar in spirit: softwood cuttings of stem sections rooted with a bit of bottom heat in spring.

Fleshy Leaves, Red Stems
Elephant bush carries small, oval to round, fleshy green leaves, sometimes edged in purple, set against reddish stems that turn woody and grey-barked with age. In cultivation it is slow growing and evergreen, never dropping its leaves for a dormant spell, and can live for decades under good care. Clusters of tiny, star-shaped pale pink flowers appear at branch tips in summer, though indoors bloom is rare and tends to need a spell of dryness followed by rain to trigger it.

Watch for Sap Suckers
Whiteflies, spider mites, and mealybugs are the pests most likely to trouble elephant bush, often arriving on new plants brought into the home. Whiteflies tend to follow excess nitrogen in the soil, spider mites give themselves away with fine webbing on leaf undersides, and mealybugs show up as waxy white clusters that resist easy removal. The RHS adds that scale insects can also be an occasional issue.

Overwatering Is the Main Risk
The single biggest threat to elephant bush is overwatering, which leads to root rot from fungal breakdown in soggy soil. Cool, damp conditions can also invite botrytis (grey mold), while powdery mildew shows up as a chalky coating that stunts growth, most often when plants move between indoors and out. Southern blight is a soil-borne fungus that is hard to treat but rarely troubles potted specimens.

Light Pruning, Careful Repotting
Because its root system is shallow and not much of an anchor, elephant bush suits hanging baskets or bonsai-style pots, and it needs little in the way of routine upkeep. Prune at the end of spring to shape the plant or keep its size in check, cutting stems back by about a third if restraint is the goal, and clearing any branches crossing through the interior. The RHS notes that overall it asks for only minimal pruning.
