Discussion

Diospyros ebenum is the historical source of the finest jet black ebony. It bears small persimmons that are attractive to birds, allowing it to become established to a limited extent in tropical southern Florida, where it is grown as an ornamental. The plant is cultivated in the Malaysian peninsula.
