Portulacaria afra variegata speckbaum dwarf jade plant

Portulacaria afra (known as elephant bush, dwarf jade plant, porkbush and spekboom in Afrikaans) is a small-leaved succulent plant found in South Africa.

It is a soft-wooded, semi-evergreen upright shrub or small tree, usually 2.5–4.5 metres (8–15 ft) tall. Similar in appearance to the unrelated "jade plant" Crassula ovata (family Crassulaceae), P. afra has smaller and rounder pads and more compact growth (shorter internodal spaces, down to 1.5 mm). It is much hardier, faster growing, more loosely branched, and has more limber tapering branches than Crassula once established.

Within the genus Portulacaria, it has been shown to be an outlier, relatively unrelated to the other species in the genus, which are all restricted to small ranges in the arid far west of southern Africa.

Distribution and habitat

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

It is also found in much denser numbers in the dryer southern Cape. Here it occurs from the "Little Karoo" of the Western Cape, eastwards up until the thicket vegetation of the Eastern Cape. Spekboom is found most prolifically in the Albany thickets, a woodland ecoregion, which locally is often called noorsveld, after the high number of succulent Euphorbia species, which are often called noors plants.

Cultivation and uses

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. Cuttings root very easily in most potting media.


It is popular as an indoor bonsai, and as a hardy xeriscaping plant. Several varieties exist - some bred in cultivation, others naturally occurring:

  • "Limpopo": A variety with much larger leaves. It is the natural form from the far north of the species' range.
  • "Prostrata": A low-lying, decumbent form that is frequently used as a ground-cover.
  • "Aurea": A compact, upright form with rounded leaves that go bright yellow in the sun.
  • "Foliis variegatus": A variegated form.
  • "Medio-picta": Variegated with a lighter centre.
  • Food source

    In southern Africa it is commonly eaten, usually as one component of a salad or a soup.

    Carbon sequestration

    It is capable of either C3 or CAM carbon fixation, depending on factors such as the season and the age of the leaves.
