Jasmine is a genus of shrubs and vines in the olive family, 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 such as chicken wire, gates or fences. The leaves can be either evergreen (green all year round) or deciduous (falling leaves in autumn).

Jasmine is widely cultivated for its 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. Many species also yield an absolute, which is used in the production of perfumes and incense.

Jasmine tisane is consumed in China, where it is called Jasmine flower tea. 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.
