|Other Uses Rating||
Succeeds in full sun and in moderate shade[
The wood is fine-textured, straight-grained, moderately heavy, with poor mechanical properties and very susceptible to rot. It has been used for making shoes, boxes and toys[
Seed - it has a hard seedcoat and may benefit from scarification before sowing to speed up germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing. Sow the seed in a partially shaded position in a nursery seedbed. A low germination rate can be expected, with the seed sprouting within 40 - 60 days[
