Kiggelaria africana

Well-shaped and reasonably robust, the low-branching, wild peach has smooth, pale grey bark that becomes rough with age. The variable leaves of this evergreen tree may resemble those of the peach. The tiny, bell-shaped flowers which bloom from August to January (spring to summer), are yellow-green, with male and female flowers on separate trees. The hard, round, knobbly, greenish yellow capsule which forms in February to July (late summer to mid-winter) splits to expose shiny black seeds, enclosed in an oily, sticky, bright orange-red coat.

The hardish, pink-brown wood is a useful general purpose timber (beams, floorboards, furniture).

Reasonably frost-hardy, it likes a moderate amount of water, and a place in the sun. Always add plenty of compost to the soil when planting, and apply a thick mulch layer (organic material, e.g. dried leaves) to protect the surface of the soil. This tree grows in both summer and winter rainfall areas. It tolerates temperatures ranging from about - 2 C to +36C.

Oncoba spinosa

A spiny shrub or small tree. The flowers are white, honey-fragrant and solitary (3" across). The fruits have a sour, edible pulp. Beautiful white and yellow camellia-like flowers look like 'fried eggs' when they drop off and fall on the ground with their yellow stamens facing upwards. Light tip pruning promotes bushy growth. Flowers attract butterflies. Blooms late spring to summer. The hard-shelled fruits are used as snuff boxes. If the fruit are left to dry with the seeds inside they it make amusing rattles for children and are also used as anklets and armlets for dancers to add rhythm when performing. The pulp of the fruit is edible, but is seldom used for that purpose. In African medicine the roots are used in the treatment of dysentery and bladder complaints. It is said that the seeds contain a drying oil that is suitable for varnish, but it is too difficult to extract to be of any commercial significance. The wood is light brown in color and can take a good polish, but the pieces are seldom large enough to be of any commercial value.
