| + | Small deciduous tree with spines, grows fast, popular from S Europe to China. Serrated leaves are oval to lance-shaped serrated. Gives tiny (5mm) cream-colored flowers in late spring, which are followed by plum-like fruit (1.5-3 cm) which become dark red when ripe, and has one hard stone in it, like that of the olive. |

| | | | |
| − | Its precise natural distribution is uncertain due to extensive cultivation, but is thought to be in southern [[Asia]], between [[Syria]], northern [[India]], and southern and central [[China]], and possibly also southeastern [[Europe]] though more likely introduced there.<ref name=rushforth>Rushforth, K.

| − | It is a small [[deciduous]] [[tree]] or [[shrub]] reaching a height of 5-10 m, usually with thorny branches. The [[leaf|leaves]] are shiny-green, ovate-acute, 2-7 cm long and 1-3 cm broad, with three conspicuous veins at the base, and a finely toothed margin. The [[flower]]s are small, 5 mm diameter, with five inconspicuous yellowish-green petals. The [[fruit]] is an edible oval [[drupe]] 1.5-3 cm long; when immature it is smooth-green, with the consistency and taste of an [[apple]], maturing dark red to purplish-black and eventually wrinkled, looking like a small [[Date Palm|date]] (hence the name Chinese Date). There is a single hard stone, similar to an [[olive]] stone.<ref name=rushforth/>

| | | | |
| − | ==Nomenclature== | + | ==Cultivation== |
| − | The species has a curious nomenclatural history, due to a combination of botanical [[International Code of Botanical Nomenclature|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 [[tautonymy|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 therefore permitted as a botanical name; this combination was made by [[Gustav Karl Wilhelm Hermann Karsten|Hermann Karsten]] in 1882.<ref name=clarke>Clarke, D.

| − | The Jujube has been cultivated for over 4,000 years for its edible fruit, and over 400 [[cultivar]]s have been selected.
| + | Tolerant of a wide range of temperatures and water, but won't give good fruit without summer heat and water during fruit development. Very drought tolerant if fruit is not important. Does well in desert with some water, can take extreme heat, down to -15C temperatures. |
| | | | |
| − | 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. This enables the jujube to grow in desert habitats, provided there is access to underground water through the summer. Virtually no temperature seems to be too high in summertime.
| |
| | | | |
| − | Many jujube trees can still be seen in the central and southern regions of [[Israel]], especially in the [[Arava Valley]], where it is the second most common tree.<!--please check to make sure the species is the same as the one described in this article--> A jujube tree near Ein Hatzeva in the Arava is estimated to be over 300 years old.

| | + | ===Propagation=== |
| | | | |
| − | ===Medicinal use=== | + | ===Pests and diseases=== |
| − | The fruits are used in Chinese and Korean [[traditional Chinese medicine|traditional medicine]], where they are believed to alleviate stress. {{Fact|date=October 2007}} The fruit is ground to powder, with very small amounts required to promptly calm nerves and purify blood quality. {{Fact|date=October 2007}} The Australian drink [[1-bil]] makes de-stressing (or relaxing) claims on the basis of its jujube ingredient.<!--It is not always ground to a powder; it may also be eaten or boiled by itself or with other herbs. Why do you say it is always ground to a powder? Also, stress is not the only condition jujube is recommended for in TCM.-->
| + | No serious pests in the USA. [[Witch's broom]]s are a wide problem in China and Korea. |
| | | | |
| − | [[Ziziphin]], a compound in the leaves of the jujube, suppresses the ability to perceive sweet taste in humans.<ref name="crfsn-32-231">[http://www.ncbi.nlm.nih.gov/sites/entrez?db=pubmed&uid=1418601&cmd=showdetailview Kurihara, Y. 1992.

Nutr. 32:231-252.]</ref> The fruit, being [[Mucilage|mucilaginous]], is also very soothing to the throat and decoctions of jujube have often been used in pharmacy to treat sore throats.
| + | ==Cultivars== |
| | + | There are over 400 cultivars of the Jujube. Here are a few selections: |
| | | | |
| − | ===Culinary use=== | + | ===Early Ripening=== |
| − | [[Image:Ziziphus jujuba MS 2461.JPG|right|thumb|Dried red jujube fruits]]
| + | * '''Li''' - Large, round fruit up to 3 ounces in mid-August. May be picked at the yellow-green stage. Tree is many-branched, yet narrow and upright. Best eaten fresh. Best first tree to have. |
| − | The freshly harvested as well as the candied dried fruits are often eaten as a snack, or with tea. They are available either red or black (called ''hóng zǎo'' or ''hēi zǎo'', respectively, in Chinese), the latter being [[Smoking (food)|smoked]] to enhance their flavour [http://www.seasonalchef.com/jujubes.htm]. In mainland China, Korea, and Taiwan, a sweetened tea syrup containing jujube fruits is available in glass jars,<sup>[http://www.megaq.co.kr/product_images/pro_images/04441649/S04441649L.jpg photo]</sup> and canned jujube tea or jujube tea in the form of teabags is also available. Although not widely available, jujube juice[http://www.tianjiaohong.com.cn/ecpjs/ZAOZHI.HTM] and jujube vinegar are also produced.[http://www.tianjiaohong.com.cn/ecpjs/ZAOCU.HTM]
| |
| | | | |
| − | In China, a wine made from jujubes called ''hong zao jiu'' (红枣酒) is also produced.[http://www.tianjiaohong.com.cn/ecpjs/ZAOJIU.HTM] Jujubes are sometimes preserved by storing in a jar filled with ''[[baijiu]]'' (Chinese liquor), which allows them to be kept fresh for a long time, especially through the winter. Such jujubes are called ''jiu zao'' (酒枣; literally "spirited jujube").
| + | ===Mid Season=== |
| | + | * '''Ed Hegard''' - Very similar to the Lang and Thornless. |
| | + | * '''GA-866''' - An outstandingly sweet selection out of the Chico Research program. Large, elongated fruit. |
| | + | * '''Jin''' - An excellent elongated fruit. Very chewy when allowed to dry on the tree. |
| | + | * '''Globe''' - A new, Chinese introduction. |
| | + | * '''Honey Jar''' - Another new, Chinese introduction. |
| | + | * '''Lang''' - Large, pear-shaped fruit which must be fully colored to be best eating. This fruit is best to let dry on the tree. Tree is upright and virtually spineless. |
| | + | * '''Redlands #4''' - Collected at an old homestead in Redlands, California. Very large, sweet, round fruit. |
| | + | * '''So''' - A tree of most beautiful shape. At each node of the stem the branch decides to go off in a new direction. Hence, a very zig-zag branching pattern which casts a beautiful shadow in the wintertime. Tree is somewhat dwarfed. |
| | + | * '''Sugar Cane''' - Small to medium fruit which can be round to elongated. Extremely sweet fruit but on a very spiny plant. The fruit is worth the spines! |
| | + | * '''Thornless''' - Just as the name implies. Very few, if any spines occur. A fruit very similar to the Lang. |
| | | | |
| − | In addition, jujubes, often stoned, are a significant ingredient in a wide variety of Chinese delicacies. In [[Persian cuisine]], the dried drupes are known as ''annab''.
| + | ===Late Season=== |
| | + | * '''Admiral Wilkes''' - Collected on a South Seas expedition in the 1840's and planted on the Capitol grounds in Washington, D.C. Elongated fruit which has been the very last to ripen, generally in mid to late November. |
| | + | * '''Chico (GI 7-62)''' - Fruit is round but flattened on the bottom. Looks like small apples. Excellent either fresh or dried. |
| | + | * '''GI-1183''' - Another cultivar from the Chico program. Large, sweet fruit. |
| | + | * '''Sherwood''' - A seedling plant from Louisiana. The fruit is very dense and sweet. Tree is very narrow and upright with leaves that are weeping in habit. |
| | + | * '''Silverhill''' - An elongated fruit which has cropped well even in northern Florida. Virtually spineless. |
| | + | * '''Tigerstooth''' - Very similar to Silverhill. |
| | + | * '''Topeka''' - From eastern Kansas and an excellent, late cropping fruit. |
