Ochna pulchra (Peeling plane)

Although the captivating Ochna pulchra can be quite challenging to grow from seed, it is well worth the effort as this is truly one of the most decorative indigenous trees and will do really well once it is established. The specific name pulchra, means beautiful, which is a most appropriate description while the Afrikaans name ‘Lekkerbreek’, refers to the brittle branches that are characteristic of these lovely trees. This elegant small tree is fairly widespread on the hills around Johannesburg and Pretoria where it can be easily identified when the distinctive flowers and fruit appear.

Bark
The distinctive bark of these lovely trees is rough and scaly on the lower trunk while the upper trunk is pale grey, peeling to reveal smooth, opalescent creamy white patches.

The hairless, fresh green, many veined leaves are alternate, elliptic to oblanceolate with margins that are slightly toothed towards the apex. The spring foliage is pale green to reddish bronze while in autumn, the leaves change to rich russet shades. 
Flowers
In early spring, the pale yellow to greenish yellow, sweetly scented flowers are borne in terminal racemes for a short while, as they fall  early.

The round seeds are black.

Best season
Spring
Hardiness

Propagation
Propagating this tree from seed can be difficult, but the best results will be achieved if very fresh seed that has not yet turned black is planted directly into soil collected from the area where the trees grow naturally. Keep moist and plant out the seedlings as soon as possible as this will ensure the highest success rate.
Growth rate
Peeling plane trees grow at an average rate of approximately 500mm per annum.
INTERESTING FEATURES
The soft, pale brown wood of Ochna pulchra has a papery feel when planed and being rather brittle, is only suitable for making small ornaments. An unpleasant smelling, greenish brown oil is obtained from the seeds which is used to polish iron as well as for the manufacture of soap and candles while the indigenous people of the Kalahari use the oil for their hair. The fruit pulp is edible but the seeds are said to be poisonous.
