Persimmons are the edible fruit of a number of species of trees in the genus Diospyros. The most widely cultivated species is the Asian persimmon, Diospyros kaki. In color the ripe fruit of the cultivated strains range from light yellow-orange to dark red-orange depending on the species and variety. The calyx generally remains attached to the fruit after harvesting, but becomes easy to remove once the fruit is ripe. The ripe fruit has a high glucose content.
