The tree is little used other than as fuel and a source of beads. However, the wood is of reasonable quality and freely available within its native range and so should be suitable for a range of uses. The tree would probably make a good pioneer species for restoring woodland and is possibly suited for shade or ornament[

Agroforestry Uses:

The tree quickly invades open areas of secondary forest and has a fast rate of growth. It also fixes atmospheric nitrogen. These qualities suggest that it would make a very good pioneer species for restoring native woodland and also for establishing woodland gardens[

The heartwood is a uniform salmon colour with occasional darker streaks; it is distinctly demarcated from the yellowish sapwood. The wood is somewhat coarse-textured, of medium weight, with indistinct growth rings, and large open pores. It is very susceptible to damage by dry-wood termites. The rate of air-seasoning is slow, and amount of degrade is moderate. Machining characteristics are as follows: planing, shaping, sanding, and resistance to screw splitting are good; turning, boring, and mortising are fair. The wood is little used, but should be suitable for furniture, millwork, construction, boxes, crates, and general carpentry[

Propagation

Like many species within the family Fabaceae, once they have been dried for storage the seeds of this species may benefit from scarification before sowing in order to speed up and improve 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[
