Rose - Scientific Classification and Uses


multi color rosesRose is a perennial flower shrub or vine of the genus Rosa, within the family Rosaceae, that contains over 100 species and comes in a variety of colors. The species form a group of erect shrubs, and climbing or trailing plants, with stems that are often armed with sharp prickles. Most are native to Asia, with smaller numbers of species native to Europe, North America, and northwest Africa. Natives, cultivars and hybrids are all widely grown for their beauty and fragrance.

Scientific classification:
Kingdom:Plantae
Division:Magnoliophyta
Class:Magnoliopsida
Order:Rosales
Family:Rosaceae
Subfamily:Rosoideae
Genus:Rosa

The leaves are alternate and pinnately compound, with sharply toothed oval-shaped leaflets. The plant's fleshy edible fruit, which ripens in the late summer through autumn, is called a rose hip. Rose plants range in size from compact, miniature roses, to climbers that can reach 7 meters in height. Species from different parts of the world easily hybridize, which has given rise to the many types of garden roses.

Roses are best known for their flowers. Roses are popular garden shrubs, as flowering shrubs. They are also grown as cut flowers, as one of the most popular and commonly sold florists' flowers. A few roses are grown for scented foliage (such as Rosa rubiginosa, ornamental thorns, Rosa sericea or their ornamental fruit Rosa moyesii). Roses are also of great value to the perfume industry. An attar of roses is distilled from the flowers. The rose hip, the fruit of some species, is used as a minor source of Vitamin C. Roses may also be planted as hedging, and for game cover.


Roses are ancient symbols of love and beauty. The rose is the national flower of England and the United States. 'Rose' means pink or red in a variety of languages, such as Romance languages, Greek, and Polish.

Rose perfumes are made from attar of roses or rose oil, which is a mixture of volatile essential oils obtained by steam distilling the crushed petals of roses. The technique originated in Persia (the word Rose itself is from Persian) then spread through Arabia and India, but nowadays about 70% to 80% of production is in the Rose Valley near Kazanluk in Bulgaria, with some production in Qamsar in Iran and Germany.
