Diospyros lotus, with common names date-plum, Caucasian persimmon, or lilac persimmon, is a widely cultivated species of the genus Diospyros, native to temperate Asia and southeast Europe. Its English name derives from the small fruit, which have a taste reminiscent of both plums and dates. It is among the oldest plants in cultivation.
Distribution and ecology
The species area extends from East Asia to the west of the Mediterranean, down to Spain. The date-plum is native to southwest Asia and southeast Europe. It was known to the ancient Greeks as "God's fruit" (Διός πυρός, Diós purós), hence the scientific name of the genus. Its English name probably derives from Persian Khormaloo خرمالو literally "date-plum", referring to the taste of this fruit which is reminiscent of both plums and dates. The fruit is called Amlok املوک in Pakistan and consumed dried. This species is one candidate for the "lotus tree" mentioned in The Odyssey: it was so delicious that those who ate it forgot about returning home and wanted to stay and eat lotus with the lotus-eaters.
The tree grows in the lower and middle mountain zones in the Caucasus. They usually grow up to 600 m (2,000 ft) above sea level. In Central Asia, it rises higher—up to 2,000 m (6,600 ft). They rarely grow in stands but often grow with hackberry, ash, maple and other deciduous species. It is not demanding on the soil and can grow on rocky slopes but requires a well lit environment.
It is cultivated at the limits of its range, as well as in the U.S. and North Africa.

This is a tree of height 15–30 m (49–98 ft) with sloughing of aging bark. The tree will commonly stop growing at 15 m (49 ft), it grows slowly and will spread in a horizontal direction as it matures.
The leaves are shiny, leathery, oval-shaped with pointed ends, 5–15 cm (2.0–5.9 in) long and 3–6 cm (1.2–2.4 in) in width.
The flowers are small, greenish, appearing in June to July. The plant is dioecious, and so obviously not self-fertile.
Fruits are berries with juicy flesh, yellow when ripe, 1–2 cm (0.39–0.79 in) in diameter. Seeds with thin skin and a very hard endosperm. Fruits ripen Oct. to Nov.

Caucasian persimmon fruits are edible and contain much sugar, malic acid, and vitamins. They are used as fresh fruits or after frost, but usually dried. Drying and frost destroy their tartness.
