A small to medium sized tree native to southern Africa. The distribution of the Kei apple extends from the Kei river in the south, from which the common name derives, northwards along the eastern side of the continent to Tanzania. This tree grows in a variety of habitats, from evergreen, coastal and riverine forests to dry woodland and rocky outcrops, where it is often associated with termite mounds.

Dovyalis caffra can reach a mature height of 3 to 5m when growing conditions are favourable. This thorny evergreen tree has a moderate growth rate. Its leaves are alternately arranged, they are also glossy green above and paler below. From November to January, D.caffra produces creamy green flowers rich in nectar. Male and female flowers on separate plants and only female plants will bear fruit. Male flowers are about 3mm long, and occur in dense clusters of 5-10 flowers, while female blooms are longer, 4-10 mm, and occur singly or in sets of 2-3. The flowers also attract a myriad of butterflies, honeybees and insects, which will of course in turn lure a lot of insect eating bird species. After flowering, fleshy yellowish-orange fruits are produced.

The Kei apple can withstand quite severe frosts and extended periods of drought, as well as the strong, gusty, salt-laden winds typical of coastal areas. It is suitable for container growing on the patio. It responds very well to pruning, and trains easily. This tree also grows well in either full sun or light shade conditions.
