Description
It is a small deciduous tree or shrub reaching a height of 5–10 metres (16–33 ft), usually with thorny branches. The leaves are shiny-green, ovate-acute, 2–7 centimetres (0.79–2.8 in) wide and 1–3 centimetres (0.39–1.2 in) broad, with three conspicuous veins at the base, and a finely toothed margin. The flowers are small, 5 millimetres (0.20 in) wide, with five inconspicuous yellowish-green petals. The fruit is an edible ovaldrupe 1.5–3 centimetres (0.59–1.2 in) deep; when immature it is smooth-green, with the consistency and taste of an apple, maturing brown to purplish-black and eventually wrinkled, looking like a small date. There is a single hard stone similar to an olive stone.
Distribution
Its precise natural distribution is uncertain due to extensive cultivation, but is thought to be in southernAsia, between Lebanon, Iran, Pakistan, India, Bangladesh, Nepal (called as Bayar), the Korean peninsula, and southern and central China, and also southeastern Europe though more likely introduced there.This plant has been introduced in Madagascar and grows as an invasive species in the western part of this island.
Nomenclature
The species has a curious nomenclatural history, due to a combination of botanical naming regulations, and variations in spelling. It was first described scientifically by Carolus Linnaeus as Rhamnus zizyphus, in Species Plantarum in 1753. Later, in 1768, Philip Miller concluded it was sufficiently distinct from Rhamnus to merit separation into a new genus, in which he named it Ziziphus jujube, using Linnaeus' species name for the genus but with a probably accidental single letter spelling difference, 'i' for 'y'; for the species name he used a different name, as tautonyms (repetition of exactly the same name in the genus and species) are not permitted in botanical naming. However, because of Miller's slightly different spelling, the combination correctly using the earliest species name (from Linnaeus) with the new genus, Ziziphus zizyphus, is not a tautonym, and was therefore permitted as a botanical name; this combination was made by Hermann Karsten in 1882.] In 2006, a proposal was made to suppress the name Ziziphus zizyphusin favor of Zizyphus jujuba, and this proposal was accepted in 2011. Ziziphus jujuba is thus the correct scientific name for this species.
Cultivation and uses
Jujube was domesticated in South Asia by 9000 BCE. Over 400 cultivars have been selected.
The tree tolerates a wide range of temperatures and rainfall, though it requires hot summers and sufficient water for acceptable fruiting. Unlike most of the other species in the genus, it tolerates fairly cold winters, surviving temperatures down to about −15 °C (5 °F). This enables the jujube to grow in mountain or desert habitats, provided there is access to underground water through the summer. The species Ziziphus jujuba grows in cooler regions of Asia. Five or more other species of Ziziphus are widely distributed in milder climates to hot deserts of Asia and Africa.
In Madagascar, jujube trees grow everywhere in the western part of the island, from the north all the way to the south. It is widely eaten by free ranging zebus, and its seeds grow easily in zebu's feces. It is an invasive species, threatening mostly protected areas.

Chinese Jujube trees are among the rarest of all fruit trees in the U.S., however, in China the Jujube Tree is the most commonly known fruit and rate as popular as the apple tree is in the U.S. The Chinese Jujube fruit can be dried into sweet, tasty snacks that last for weeks, even after no refrigeration.
The Chinese Jujube fruit is almost round in some varieties and elongated like a kumquat in others. Some people like to eat the Chinese Jujube cultivar green straight off the tree, but most prefer to pick the Jujube fruit when amber spots appear, or even wait until the fruit is completely brown. The Chinese Jujube fruit ripens well on a kitchen counter or in the refrigerator. The Chinese Jujube trees are cold hardy down to -25*F.
