The persimmon is a fruit that comes from certain trees in the genus Diospyros. Like the tomato, it is technically a berry but rarely considered one. The fruit is picked in late fall and sometimes stays on the tree into winter. Depending on the strain, the color ranges from yellow to dark red-orange. While some persimmons are spherical, others have the shape of an acorn or pumpkin. In size, they can be anywhere from the size of a half-dollar to a small grapefruit.
