A persimmon is an edible fruit (a berry, specifically) that grows on a variety of trees in the genus Diospyros. The most widely cultivated among these is the Diospyros kaki, or the Asian persimmon.
When ripe, persimmons range in color from light yellow to dark red-orange. They range in size and shape, too. You can find persimmons as small as three-fourths of an inch in diameter or as large as three and a half inches in diameter. Some are rounded, while others are heart- or pumpkin-shaped
