We have no more information on the wood of this species, but a general description of the wood for the American members of this genus is as follows:-
The heartwood is yellowish or whitish; it is not distinct from the sapwood, though traumatic heartwood can be dark brown or purplish. The texture is medium to coarse; the grain straight to irregular; lustre medium; thre is no distinctive odour or taste. The wood is generally reported to be very susceptible to attack by decay fungi. Most species are relatively easy to air season, with only slight checking and moderate warp, particularly in thinner boards. It is easy to work and finishes smoothly in all operations. The wood is used for purposes such as rough construction lumber, particleboard and fiberboard, general carpentry, plywood, and furniture components[

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 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[
