 by insects and wind. Fruiting typically begins when the tree is about six years old.

The fruit is round or oval and usually orange-yellow, ranging to bluish, in color and from 2 centimetre in diameter. In the American South and Midwest, the fruits are referred to as simply persimmons or "'simmons", and are popular in desserts and cuisine.

Commercial varieties include the very productive Early Golden, the productive John Rick, Woolbright, and Miller and the Ennis–seedless variety. Another nickname of the American persimmon, the 'date-plum', actually refers to a variety of persimmon found in South Asia, Diospyros lotus.

Description

It is a small tree usually thirty to eighty feet (ten to twenty-four meters) in height, with a short, slender trunk and spreading, often pendulous branches, which form sometimes a broad and sometimes a narrow round-topped head. The roots are thick, fleshy and stoloniferous. It is also given to shrubby growth.
The tree has oval entire leaves, and unisexual flowers on short stalks. In the male flowers, which are numerous, the stamens are sixteen in number and arranged in pairs; the female flowers are solitary, with traces of stamens, and a smooth ovary with one ovule in each of the eight cells—the ovary is surmounted by four styles, which are hairy at the base. The fruit-stalk is very short, bearing a subglobose fruit an inch in diameter or a bit larger, of an orange-yellow color, ranging to bluish, and with a sweetish astringent pulp. It is surrounded at the base by the persistent calyx-lobes, which increase in size as the fruit ripens. The astringency renders the fruit somewhat unpalatable, but after it has been subjected to the action of frost, or has become partially rotted or "bletted
Bletting
Bletting is a process that certain fleshy fruits undergo when, beyond ripening, they have started to decay and ferment. There are some fruits that are either sweeter after some bletting, such as sea buckthorn, or for which most varieties can be eaten raw only after bletting, such as medlars,...

  • Bark: Dark brown or dark gray, deeply divided into plates whose surface is scaly. Branchlets slender, zigzag, with thick pith or large pith cavity; at first light reddish brown and pubescent. They vary in color from light brown to ashy gray and finally become reddish brown, the bark somewhat broken by longitudinal fissures. Astringent and bitter.
  • Wood: Very dark; sapwood yellowish white; heavy, hard, strong and very close grained. Specific gravity, 0.7908; weight of cubic foot, 49.28 lb (22.4 kg).
  • Winter buds: Ovate, acute, one-eighth of an inch long, covered with thick reddish or purple scales. These scales are sometimes persistent at the base of the branchlets.
  • Leaves: Alternate, simple, four to six inches (152 mm) long, oval, narrowed or rounded or cordate at base, entire, acute or acuminate. They come out of the bud revolute, thin, pale, reddish green, downy with ciliate margins, when full grown are thick, dark green, shining above, pale and often pubescent beneath. In autumn they sometimes turn orange or scarlet, sometimes fall without change of color. Midrib broad and flat, primary veins opposite and conspicuous. Petioles stout, pubescent, one-half to an inch in length.
  • Flowers: May, June, when leaves are half-grown; diœcious or rarely polygamous. Staminate flowers borne in two to three-flowered cymes; the pedicels downy and bearing two minute bracts. Pistillate flowers solitary, usually on separate trees, their pedicels short, recurved, and bearing two bractlets.
  • Calyx: Usually four-lobed, accrescent under the fruit.
  • Corolla: Greenish yellow or creamy white, tubular, four-lobed; lobes imbricate in bud.
  • Stamens: Sixteen, inserted on the corolla, in staminate flowers in two rows. Filaments short, slender, slightly hairy; anthers oblong, introrse, two-celled, cells opening longitudinally. In pistillate flowers the stamens are eight with aborted anthers, rarely these stamens are perfect.
  • Pistil: Ovary superior, conical, ultimately eight-celled; styles four, slender, spreading; stigma two-lobed.
  • Fruit: A juicy berry containing one to eight seeds, crowned with the remnants of the style and seated in the enlarged calyx; depressed-globular, pale orange color, often red-cheeked; with slight bloom, turning yellowish brown after freezing. Flesh astringent while green, sweet and luscious when ripe.

Uses

The peculiar characteristics of its fruit have made the tree well known. This fruit is a globular berry, with variation in the number of seeds, sometimes with eight and sometimes without any. It bears at its apex the remnants of the styles and sits in the enlarged and persistent calyx. It ripens in late autumn, is pale orange with a red cheek, often covered with a slight glaucous bloom. One joke among Southerners is to induce strangers to taste unripe persimmon fruit, as its very astringent bitterness is shocking to those unfamiliar with it. Folklore states that frost is required to make it edible, but fully ripened fruit lightly shaken from the tree or found on the ground below the tree is sweet, juicy and delicious. The peculiar astringency of the fruit is due to the presence of a tannin similar to that of Cinchona

Cinchona or Quina is a genus of about 38 species in the family Rubiaceae, native to tropical South America. They are large shrubs or small trees growing 5–15 metres in height with evergreen foliage. The leaves are opposite, rounded to lanceolate and 10–40 cm long. The flowers are white, pink...

Cultivation

The tree prefers light, sandy, well-drained soil, but will grow in rich, southern, bottom lands. It can be grown in northern Ohio only with the greatest of care, and in southern Ohio its fruit is never edible until after frost.

The tree is greatly inclined to vary in the character and quality of its fruit, in size this varies from that of a small cherry to a small apple. Some trees in the south produce fruit that is delicious without the action of the frost, while adjoining trees produce fruit that never becomes edible.

It was brought to England before 1629 and is cultivated, but rarely if ever ripens its fruit. It is easily raised from seed and can also be propagated from stolons, which are often produced in great quantity. The tree is hardy in the south of England and in the Channel Islands.

In respect to the power of making heartwood, the locust and persimmon stand at the extreme opposite ends of the list.

 (of which it is not a true variety).

It is a common misconception persimmon fruit needs frost to ripen and soften. Some, such as the early-ripening varieties "pieper" and "NC21"(also known as "supersweet"), easily lose astringency and become completely free of it when slightly soft at the touch—these are then very sweet, even in the British climate. On the other hand, some varieties (like the very large fruited "yates", which is a late ripening variety) remain astringent even when the fruit has become completely soft (at least in the British climate). Frost, however, destroys the cells within the fruit, causing it to rot instead of ripen. Only completely ripe and soft fruit can stand some frost; it will then dry and become even sweeter (hence the misconception). The same goes for the oriental persimmon (Diospyros kaki), where early frost can severely damage a fruit crop.
