Jengkol plants grown by seeds or seedlings will begin to bear fruit when it is five years old or more. If Jengkol tree growing through the graft, the fruiting period will be much shorter. The leaves are green, elongated oval-shaped with a slightly pointed tip, lighter-colored veins. Has a taproot, and able to withstand large amounts of ground water.


One other characteristic of this tree is the tops of the leaves in the form of young leaves have a purple red color. The leaf color will turn greenish when old.  Generally grows wild, leafy tree, so that it fits into the tree shade.
