Answer 1

Jasmine is a member of about 200 species of shrubs and climbing vines. Mature plants are usually up to 3 meters high and 2 meters wide. True jasmine is a climbing vine with oval, shiny leaves and tubular, waxy-white flowers. Two types of jasmine are used for oil production - J. grandiflorum and J. officinale.
Indigenous to the foot hills of Himalayas and plains of Ganges. Commercially cultivated in the temperate regions of India especially Uttar Pradesh and Andhra Pradesh. It has been taken to China, France and Mediterranean regions.

Since ancient times Jasmine has been thought of as the 'queen of flowers'. The name Jasmine is derived from the Persia 'yasmin', meaning a fragrant flower. It's also a Persian girl name. In India some varieties are used as religious offerings symbolizing divine hope.
Sambac, is an evergreen white-flowered climber, 6 or 8 ft. high, introduced into Britain in the latter part of the 17th century. Two varieties introduced somewhat later are respectively 3-leaved and double-flowered, and these, as well as that with normal flowers, bloom throughout the greater part of the Jasminum grandiflorum;
The Spanish, or Catalonian jasmine, J. grandiflorum, a native of the north-west Himalaya, and cultivated both in the old and new world, is very like J. officinale, but differs in the size of the leaflets; the branches are shorter and stouter, and the flowers very much larger, and reddish underneath.
The distinguishing characters of J. odoratissimum, a native of the Canary Islands and Madeira, consist principally in the alternate, obtuse, ternate and pinnate leaves, the 3-flowered terminal peduncles and the 5-cleft yellow corolla with obtuse segments. In China J. paniculatum is cultivated as an erect
shrub, known as sieu-hing-hwa; it is valued for its flowers, which are used with those of J. Sambac, in the proportion of 10 lb of the former to 30 lb of the latter, for scenting tea. Its leaves are of a bright shining green; its large terminal flowers are white with a faint tinge of red, fragrant and blooming throughout the year. Other hardy species commonly cultivated in gardens are the low or Italian yellow-flowered jasmine, J. humile, an East Indian species introduced and now found
wild in the south of Europe, an erect shrub 3 or 4 ft. high, with angular branches, alternate and mostly ternate leaves, blossoming from June to September; the common yellow jasmine, J. fruticans, a native of
southern Europe and the Mediterranean region, a hardy evergreen shrub, 10 to 12 ft. high, with weak, slender stems requiring support, and bearing yellow, odourless flowers from
spring to autumn.
