Dalbergia delphinensis is a small, deciduous tree[
The tree is selectively felled in the wild for its high quality timber, which is exported[
Selective felling for export, coupled with the fragmented and declining state of the habitat has brought the species into danger. Its restricted distribution coincides with a proposed site for titanium mining, which threatens all the remaining forest in the area. The plant is classified as 'Endangered' in the IUCN Red List of Threatened Species(2011)[
Africa - southeastern Madagascar.

Prefers a moist, sandy soil in the wild[
]. In cultivation they are likely to do well in a fertile, loam soil and a position in full sun[
A high quality timber[
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[
Softwood cuttings of many species, especially if taken from younger plants, will root in a well-drained, sandy medium in a closed case with bottom heat[
