The wood is moderately heavy, porous, soft with thick fibres, of low durability in contact with the soil or humidity. It can be used in construction for purposes such as beams, rafters, frames etc; and is also used in carpentry and for making matches and boxes[
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. Germination can be expected within 24 - 40 days[
