The heartwood is light pinkish to reddish-grey, or in some cases nearly white towards the outside of the log; it is not distinctly demarcated from the sapwood. Texture is medium to fine, the grain straight, the wood lustrous, with a smooth feel. The wood is light in weight, soft and fairly durable. It is easy to saw, works well by hand and on machine, and finishes to a dull smooth surface. If cut on the quarter it presents a noticeable silver grain, which should be taken advantage of in cabinet work, as it apparently does not warp much if so cut. It is used for boatbuilding, well construction, rice pounders, cabinet work, and carts[, ]. The wood turns black if buried in mud[].

Propagation

Seed - best sown as soon as it is ripe in a position in full light. About 90% of fresh seed germinates[].
Cuttings of half-ripe wood[].
