Jasmine

 


Jasmines can be either deciduous (leaves falling in autumn) or evergreen (green all year round), and can be erect, spreading, or climbingshrubs and vines. Their leaves are borne opposite or alternate. They can be simple, trifoliate, or pinnate. The flowers are typically around 2.5 cm (0.98 in) in diameter. They are white or yellow in color, 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.[6][7]
The basic chromosome number of the genus is 13, and most species are diploid (2n=26). However, natural polyploidy exists, particularly in Jasminum sambac (2n=39), Jasminum flexile (2n=52), Jasminum primulinum (2n=39), and Jasminum angustifolium (2n=52)

Jasmine Flowers

Although there are about 200 different species of this flower, three of the most common consist of the white, yellow and Japanese varieties. These plants can grow up to 15 feet in their life span, and most of the vine varieties are considered healthy ‘climbers.’ These vines can grow onto other plants or be trained to grow through picket fences, shrubs, or around artfully arranged pieces of chicken wire.
