Dispyros austro-africana tree

Diospyros austro-africana is a beautiful indigenous shrub or tree that bears little cream, pink and even red lantern-like flowers. Not only attractive to man but also to birds and butterflies, it grows in different regions and conditions across the country.

Diospyros austro-africana is a multistemmed shrub or small tree, somewhat rounded, 2 to 10 m high. The bark is medium to dark brown with fine, flakey strips. The brown branches are finely haired, similar to the fine hairs on the small, narrow-obovate leaves which give this shrub a dusty grey appearance.

The leaves are whorled and crowned at the tips. They are 35 x 2-5 mm, subsessile, oblanceolate, slightly darker and velvety on top and felted beneath.

The flowers are pendulous, creamy white, cherise-pink or red. Each flower is surrounded by a 5-lobed calyx which holds the developing fruit and is unique to Diospyros. Plants are dioecious, either male or female. Flowering time: August to November

Round, fleshy fruits are borne from January to June. These are also velvety and ripen red to black. The fruit is usually 15 mm in diameter.

Conservation status
Diospyros austro-africana is not a threatened species and therefore has no conservation status.

Distribution and habitat
There are four varieties of this species (a variety means a subdivision of a species). Diospyros austro-africana var. austro-africana occurs in the Western Cape regions and north towards Namaqualand; var. microphylla is the most common and widespread, occurring in the Western Cape, Northern Cape, Free State and further north of the Vaal River; var. rubiflora occurs inland from the Free State, Lesotho to KwaZulu-Natal; var. rugosa occurs in the Western Cape.

Generally this is a water-wise plant that can tolerate cold temperatures and severe frost. It is suited to the winter rainfall regions of Western Cape, KwaZulu-Natal and northern South Africa.

Derivation of name and historical aspects
Diospyros austro-africana belongs to the family Ebenaceae. It was previously known as Royena hirsuta. There are two genera, Diospyros and Euclea.

The common name of the genus Diospyros is persimmon or tolbos. It is characterized by: the calyx (composed of sepals) which usually increases in size after flowering; the ovary is borne on a smooth, hairless disc; fruits carry 2 or more seeds; leaves are alternate.

There are 500 species in the genus and these are found in pantropical and tropical areas. Diospyros is derived from the Greek, dios meaning divine, and pyros meaning wheat or grain.

Diospyros austro-africana is water-wise with characteristics such as tiny leaves and felt-like hairs.

Speckled and Red-faced Mousebirds, Black-collared, Pied and Crested Barbets, Black-eyed Bulbuls and Red-winged Starlings enjoy the fruits of this shrub. The flowers attract insects and they are eaten by Southern Boubou, flycatchers, white-eyes, robins and thrushes. The larvae of the Natal Copper butterfly feed off this plant.

Uses and cultural aspects
The wood of Diospyros austro-africana is used to make fire. The fruits are also edible. This shrub has good potential as a bonsai.

Growing Diospyros austro-africana

Even though this plant is considered water-wise, moderate watering will benefit it, as well as a good potting mix with compost. Diospyros austro-africana is slow growing, a good rockery plant and can be used in a mixed border or as a screening shrub.

It is grown from seed. Propagate from seeds as the cuttings are very difficult to root. Fresh seeds grow much better than stored seeds. Collect the seeds when ripe and clean them as soon as possible. Use 50% sand and 50% seedling mixture in the trays. Cover the seeds with the mixture. Place the trays on hotbeds and do not allow them to dry out.

The seeds will germinate within three weeks. After a week of germination, allow the seedlings to harden off. Seedlings can be transplanted after a month in the hardening off area or can stay in the seedling tray for years. The plants need full sun and well-drained soil.
