Jasminium (Arabic name, from which have come Jessamine, Jasmin and Jasminum). Oleaceae. Jasmine. Jessamine. Climbing or erect shrubs, with attractive flowers, mostly very fragrant, prized for planting in mild climates and frequently grown under glass.
 
 
 
Leaves opposite or alternate, pinnate but sometimes reduced to 1 lft.(petiole jointed): fls. on the ends of the branchlets, or twin, or in dichotomous cymes; corolla yellow or white, sometimes reddish, salver-shaped, the 4-9 or more lobes convolute in the bud, much exceeding the calyx; stamens 2, included in the corolla-tube; ovary 2-loculed, with 1-4 erect ovules: fr. a 2-lobed berry, or sometimes the carpels separate, the carpels mostly 2-seeded.—Probably upwards of 200 species, widely distributed in warm parts of Eu., Asia, Afr., and the Pacific region; nearly absent from Amer. The genus is closely allied to Ligustrum, but differs in the compound lvs. and twin-carpeled frs. Olea is also a related genus.
 
 
 
Jasmines are of diverse horticultural groups. Some of them are hardy in the middle and southern states, whereas others are winter-flowering warmhouse plants. Most of them are known as coolhouse or temperate- house shrubs, of half-climbing habit. They are all of easy culture. They propagate readily by cuttings of nearly mature wood and by layers. The species are usually called jasmines although the word jessamine is really the same. J. officinale is the jessamine of poetry. Some of them (particularly J. grandiflorum) are grown for perfume-making. The Cape jessamine is Gardenia, although there is a Jasminum capense. Yellow or Carolina jessamine is Gelsemium. The hardiest kinds are J. humile, J. fruticans, J. floridum, J. nudiflorum, J. primulinum, J. officinale, but none of them is reliable north of Washington without protection, and even then only seldom north of Philadelphia.

'''Jasmine''' or '''Jessamine''' (''Jasminum'') is a genus of [[shrub]]s and [[vine]]s in the olive family ([[Oleaceae]]), with about 200 species, native to tropical and warm temperate regions of the [[Old World]]. The majority of species grow as climbers on other plants or on structures. The [[leaf|leaves]] can be either [[evergreen]] or [[deciduous]], and are opposite in most species; leaf shape is simple, trifoliate or [[pinnate]] with up to nine leaflets.
 
 
 
Jasmine [[flower]]s are generally white, although some species have yellow flowers. Unlike most genera in the Oleaceae which have four corolla lobes ("petals"), jasmines often have five or six lobes. They are often strongly and sweetly scented. Flowering is in spring or summer in most species, but in a few species, notably ''J. nudiflorum'', in winter on the bare branches of this deciduous species.

===Cultivation and uses===
 
[[Image:Malligai_Ramabaanam.jpg|thumb|left|''Jasminum sambac'' flowers harvested for Malligai - Raama Baanam]]
 
Jasmines are widely cultivated for their flowers, enjoyed in the [[garden]], as house plants, and as cut flowers. The flowers are worn by women in their hair in southern and southeast Asia. Some claim that the daily consumption of Jasmine tea is effective in preventing certain cancers. Many species also yield an [[absolute (substance)|absolute]] which is used in the production of [[perfume]]s and [[incense]].
 
 
 
Jasmine [[tisane]] is consumed in [[China]], where it is called Jasmine flower tea (茉莉花茶; [[pinyin]]: mò lì huā chá).  [[Jasminum sambac]] flowers are also used to make [[tea]], which often has a base of [[green tea]], but sometimes an [[Oolong]] base is used. The delicate Jasmine flower opens only at night and is plucked in the morning when the tiny petals are tightly closed. They are then stored in a cool place until night. Between six and eight in the evening, as the temperature cools, the petals begin to open. Flowers and tea are "mated" in machines that control temperature and humidity. It takes four hours or so for the tea to absorb the fragrance and flavour of the Jasmine blossoms, and for the highest grades, this process may be repeated as many as seven times. Because the tea has absorbed moisture from the flowers, it must be refired to prevent spoilage. The spent flowers may or may not be removed from the final product, as the flowers are completely dry and contain no aroma. Giant fans are used to blow away and remove the petals from the denser tea leaves.  If present, they simply add visual appeal and are no indication of the quality of the tea.  Typically, Jasmine petals left in the tea are for export, whereas domestic Chinese tastes prefer the petals removed from the tea.

''Jasminum sambac'' is also the [[National emblem|National Flower]] of [[Indonesia]], where it is known as "Melati", and of the [[Philippines]], where it is known as  "[[Sampaguita]]". In Indonesia (especially the island of Java), it is the most important flower in wedding ceremonies for ethnic Indonesians. ''Jasminum officinale'' is the national flower of [[Pakistan]], where it is known as the "Chambeli" or "Yasmine". In [[Sanskrit]] it is called Mallika.  Jasmine is cultivated at [[Pangala]], in [[Karnataka]], India, and exported to [[Middle East]] countries{{Fact|date=February 2007}}.
 
 
 
''J. fluminense'' is an [[invasive species]] in [[Hawaii]], where it is sometimes known by the inaccurate name "Brazilian Jasmine". ''J. dichotomum'' is also invasive in [[Florida]]. <br clear = left>
 
 
 
In [[Thailand]], jasmine flowers are used as a symbol of the [[mother]].
