I have not grown this plant. It is native to South Africa, Swaziland, Zimbabwe, northern and eastern Botswana, northern Namibia and tropical Africa north to Ethiopia and can be found in woodlands, wooded grasslands and along riverbanks. The leaveas are blue-grey and pinnate. The branches and sometimes the leaves are covered with yellow hairs. Birds love to build their nests in it with Pied and Crested Barbets make their nesting holes in the trunks. The seedpod is often invaded by insects that feed on the seeds and eaten by stock, birds andgame. The seedpods contain prussic acid and may be poisonous. The gum it produces is edible and it is a good adhesive. Twine from the inner bark is used for threading beads.
