The specific virginian epithet comes from Virginia, Virginian, a reference that should not be made only and so much to the current Virginia, a state of the eastern USA of rather limited dimensions, but to the original conditions in which Virginia was an area that covered the East coast of the West Indies under British rule, ie from French Canada to Spanish Florida. It is also recalled that Virginia took its name from Elizabeth I Tudor (1533-1603), called the Virgin Queen, never having married.

Geographic Distribution and Habitat –
The American persimmon is a plant originating in an area that includes eastern North America: from New England to Florida, west from Texas to Kansas.
Its habitat is that of dry woods, old fields and clearings where it grows preferably on light, well-drained sandy soils but is found on most types of soil, from sands to shales and muddy bottoms.

Description –
Diospyros virginiana is a deciduous tree that can grow up to 20.00 meters in height.
In summer produces perfumed flowers that are dioecies, so it is necessary to have both male and female plants to obtain fruit. Most cultivars are partenocarpic (with fruits without seeds obtained without pollination).
The flowers are pollinated by insects and wind. Fruiting typically begins when the tree is about 6 years old.
The fruit is round or oval in shape and usually yellow-orange, sometimes bluish, ranging in size from 2 to 6 cm in diameter.

Cultivation –
The American persimmon is a plant that requires a good deep clay soil and in a sunny position or in light shade.
If grown for its fruit, the tree needs a warm, sunny and sheltered location. It does not like very acidic or humid and poorly drained soils.
It is a plant that resists up to -35 ° C; for a good vegetative restart, in spring, it is best to cultivate the plants in a sheltered position exposed to the early morning sun.
Even if it is a dioecious plant it can produce fruit (via parthenocarpy) without seeds in the absence of a pollinator.
The plants have a long taproot and are difficult to transplant; in fact it is best to plant them in their permanent position as soon as possible and protect them during the winter for the first two years.
Trees can start producing fruit when they are only a few years old. This species is occasionally grown for its edible fruits, there are several varieties.
Propagation can take place by seed which must be sown in a cold greenhouse as soon as it is ripe.
It usually germinates in 1 – 6 months at 15 ° C.
Propagation can also take place by woody cutting at mid-ripening in the midsummer period.
Commercial varieties include the very productive Early Golden, the productive John Rick, Miller, Woolbright and the Ennis, a seedless variety.
