It can be used as a pioneer species when restoring woodland and is a very ornamental tree, though it is not as yet cultivated[

Propagation

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. Seedlings are very sensitive to root disturbance, so the seed is best sown as soon as it is ripe in a partially shaded position in individual containers. A very low germination rate can be expected from untreated seed, with the seed sprouting within 30 - 50 days[
