Description

Jasminum angulare, the wild jasmine or angular jasmine, is a species of flowering plant in the family Oleaceae that is indigenous to South Africa. This scrambling evergreen shrub can be grown in the sun or semi-shade. It has pinnate leaves and masses of white, strongly-scented, star-shaped flowers which attract a variety of birds. This is one of around 10 species of jasmine that naturally occur in South Africa. It does not tolerate being frozen, so in temperate regions it is best grown under glass, in an unheated greenhouse or conservatory. In the UK it has gained the Royal Horticultural Society’s Award of Garden Merit. Jasmine (taxonomic name: Jasminum) is a genus of shrubs and vines in the olive family (Oleaceae). It contains around 200 species native to tropical and warm temperate regions of Eurasia, Africa, and Oceania. Jasmines are widely cultivated for the characteristic fragrance of their flowers. A number of unrelated plants contain the word "jasmine" in their common names (see Other plants called "jasmine"). Jasmine can be either deciduous (leaves falling in autumn) or evergreen (green all year round), and can be erect, spreading, or climbing shrubs and vines. Their leaves are borne in opposing or alternating arrangement and can be of simple, trifoliate, or pinnate formation. The flowers are typically around 2.5 cm (0.98 in) in diameter. They are white or yellow, although in rare instances they can be slightly reddish. The flowers are borne in cymose clusters with a minimum of three flowers, though they can also be solitary on the ends of branchlets. Each flower has about four to nine petals, two locules, and one to four ovules. They have two stamens with very short filaments. The bracts are linear or ovate. The calyx is bell-shaped. They are usually very fragrant. The fruits of jasmines are berries that turn black when ripe. The basic chromosome number of the genus is 13, and most species are diploid (2n=26). However, natural polyploidy exists, particularly in Jasminum sambac (triploid 3n=39), Jasminum flexile (tetraploid 4n=52), Jasminum mesnyi (triploid 3n=39), and Jasminum angustifolium (tetraploid 4n=52). Jasmines are native to tropical and subtropical regions of Eurasia, Africa, Australasia and Oceania, although only one of the 200 species is native to Europe. Their center of diversity is in South Asia and Southeast Asia.
