A rose is a woody perennial of the genus Rosa, within the family Rosaceae. There are over 100 species. They form a group of erect shrubs, and climbing or trailing plants, with stems that are often armed with sharp prickles. Flowers are large and showy, in colors ranging from white through yellows and reds. Most species are native to Asia, with smaller numbers native to Europe, North America, and northwest Africa. Species, cultivars and hybrids are all widely grown for their beauty and fragrance. Rose plants range in size from compact, miniature roses, to climbers that can reach 7 meters in height. Different species hybridize easily, and this has been used in the development of the wide range of garden roses.
Pink Rose The Natural Color of Roses
The aggregate fruit of the rose is a berry-like structure called a rose hip. Many of the domestic cultivars do not produce hips, as the flowers are so tightly petalled that they do not provide access for pollination. The hips of most species are red, but a few (e.g. Rosa pimpinellifolia) have dark purple to black hips. Each hip comprises an outer fleshy layer, the hypanthium, which contains 5–160 "seeds" (technically dry single-seeded fruits called achenes) embedded in a matrix of fine, but stiff, hairs. Rose hips of some species, especially the Dog Rose (Rosa canina) and Rugosa Rose (Rosa rugosa), are very rich in vitamin C, among the richest sources of any plant. The hips are eaten by fruit-eating birds such as thrushes and waxwings, which then disperse the seeds in their droppings. Some birds, particularly finches, also eat the seeds.

The genus Rosa is subdivided into four subgenera:
Hulthemia (formerly Simplicifoliae, meaning "with single leaves") containing one or two species from southwest Asia, R. persica and Rosa berberifolia which are the only roses without compound leaves or stipules.
Hesperrhodos (from the Greek for "western rose") contains Rosa minutifolia and Rosa stellata, from North America.
Platyrhodon (from the Greek for "flaky rose", referring to flaky bark) with one species from east Asia, Rosa roxburghii.
Rosa (the type subgenus) containing all the other roses. This subgenus is subdivided into 11 sections.
Banksianae - white and yellow flowered roses from China.
Bracteatae - three species, two from China and one from India.
Caninae - pink and white flowered species from Asia, Europe and North Africa.
Carolinae - white, pink, and bright pink flowered species all from North America.
Chinensis - white, pink, yellow, red and mixed-color roses from China and Burma.
Gallicanae - pink to crimson and striped flowered roses from western Asia and Europe.
Gymnocarpae - one species in western North America (Rosa gymnocarpa), others in east Asia.
Laevigatae - a single white flowered species from China
Pimpinellifoliae - white, pink, bright yellow, mauve and striped roses from Asia and Europe.
Rosa (syn. sect. Cinnamomeae) - white, pink, lilac, mulberry and red roses from everywhere but North Africa.
Synstylae - white, pink, and crimson flowered roses from all areas.
