The Persimmon is the fruit of an Asian tree, Diospyros kaki of the ebony fmily, Ebenaceae. It is considered a true berry. The fruits are very sour and astringent when immature, but very sweet and juicy when ripe. The fruit is known in Japanese as kaki.
The most popular cultivars are the "Fuyu," a stout, orange fruit that is very sweet, and the "Hachiya," a red, larger variety that is slightly more sour than the Fuyu variety.
