Roses
Rose is a type of shrub plant from the genus Rosa as well as the name of the flower produced by this plant. Wild roses consist of more than 100 species, mostly growing in the northern hemisphere, which is cool. Rose species are generally thorny shrubs or climbing plants that can reach 2 to 5 meters in height. Although rarely found, the height of roses that propagate on other plants can reach 20 meters. Most species have leaves that are between 5-15 cm long with two opposite (pinnate). Compound leaves which each petiole consists of at least 3 or 5 to 9 or 13 leaflets and supporting leaves (stipules) oval in shape, pinnately boned, edged with ridges, tapering at the tips of the leaves and spiny on the stems close to the ground. Roses are not actually tropical plants, most species lose their leaves completely and only a few species in Southeast Asia are always green throughout the year. The flowers consist of 5 petals with the exception of Rosa sericea which only has 4 petals. Among the colors possessed by roses are white, pink, yellow and blue in some species. The ovaries are on the underside of the corolla and petals.
