Persimmons can be a dioecious tree, that's to say, trees with only male flowers and trees with only female flowers. In this case, since these types of trees do not self-pollinate, we need to have both types of trees in order female trees can produce fruits.
In most cases trees that are planted are hermaphrodites, so, they have male flowers and female flowers in the same tree. Pollination is entomophilous. The trees are usually pollinated by insects such as bees.
Persimmons reach between 5 and 17 meters high, but usually their height is over 10 meters and its top reaches about 5 or 6 meters in diameter. Leaves alternate, oval, hard, about 13 to 15 cm long, bright green to golden yellow to become the fall.
Female flowers of creamy yellow that spring from the axils of the leaves individually. The male flowers are pink in color and are grouped into groups of 3.
Persimmons belong to the genus Diospyros which in Greek means "divine fire" (Dios = god + pyros = fire). This name is due to the orange or reddish skin and to the great sweetness of the fruit when fully ripe.

Persimmon fruit characteristics
