A rose is either a woody perennial flowering plant of the genus Rosa ( // ), in the family Rosaceae ( // ), or the flower it bears. There are over three hundred species and tens of thousands of cultivars.[ citation needed ] They form a group of plants that can be erect shrubs, climbing, or trailing, with stems that are often armed with sharp prickles. Their flowers vary in size and shape and are usually large and showy, in colours ranging from white through yellows and reds. Most species are native to Asia, with smaller numbers native to Europe, North America, and northwestern Africa. Species, cultivars and hybrids are all widely grown for their beauty and often are fragrant. Roses have acquired cultural significance in many societies. Rose plants range in size from compact, miniature roses, to climbers that can reach seven meters in height. Different species hybridize easily, and this has been used in the development of the wide range of garden roses.
The name rose comes from Latin rosa, which was perhaps borrowed from Oscan, from Greek ῥόδον rhódon (Aeolic βρόδον wródon), itself borrowed from Old Persian wrd- (wurdi), related to Avestan varəδa, Sogdian ward, Parthian wâr.
The leaves are borne alternately on the stem. In most species they are 5 to 15 centimetres (2.0 to 5.9 in) long, pinnate, with (3–) 5–9 (–13) leaflets and basal stipules; the leaflets usually have a serrated margin, and often a few small prickles on the underside of the stem. Most roses are deciduous but a few (particularly from Southeast Asia) are evergreen or nearly so.
The flowers of most species have five petals, with the exception of Rosa omeiensis and Rosa sericea , which usually have only four. Each petal is divided into two distinct lobes and is usually white or pink, though in a few species yellow or red. Beneath the petals are five sepals (or in the case of some Rosa omeiensis and Rosa sericea, four). These may be long enough to be visible when viewed from above and appear as green points alternating with the rounded petals. There are multiple superior ovaries that develop into achenes.Roses are insect-pollinated in nature.
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 sharp growths along a rose stem, though commonly called "thorns", are technically prickles, outgrowths of the epidermis (the outer layer of tissue of the stem), unlike true thorns, which are modified stems. Rose prickles are typically sickle-shaped hooks, which aid the rose in hanging onto other vegetation when growing over it. Some species such as Rosa rugosa and Rosa pimpinellifolia have densely packed straight prickles, probably an adaptation to reduce browsing by animals, but also possibly an adaptation to trap wind-blown sand and so reduce erosion and protect their roots (both of these species grow naturally on coastal sand dunes). Despite the presence of prickles, roses are frequently browsed by deer. A few species of roses have only vestigial prickles that have no points.
The oldest remains of roses are from the Late Eocene Florissant Formation of Colorado.Roses were present in Europe by the early Oligocene.
Today's garden roses come from 18th-century China.Among the old Chinese garden roses, the Old Blush group is the most primitive, while newer groups are the most diverse.

The genus Rosa is composed of 140–180 species and divided into four subgenera:
Roses are best known as ornamental plants grown for their flowers in the garden and sometimes indoors. They have been also used for commercial perfumery and commercial cut flower crops. Some are used as landscape plants, for hedging and for other utilitarian purposes such as game cover and slope stabilization.
The majority of ornamental roses are hybrids that were bred for their flowers. A few, mostly species roses are grown for attractive or scented foliage (such as Rosa glauca and Rosa rubiginosa ), ornamental thorns (such as Rosa sericea ) or for their showy fruit (such as Rosa moyesii ).
Ornamental roses have been cultivated for millennia, with the earliest known cultivation known to date from at least 500 BC in Mediterranean countries, Persia, and China.It is estimated that 30 to 35 thousand rose hybrids and cultivars have been bred and selected for garden use as flowering plants. Most are double-flowered with many or all of the stamens having morphed into additional petals.
In the early 19th century the Empress Josephine of France patronized the development of rose breeding at her gardens at Malmaison. As long ago as 1840 a collection numbering over one thousand different cultivars, varieties and species was possible when a rosarium was planted by Loddiges nursery for Abney Park Cemetery, an early Victorian garden cemetery and arboretum in England.
Roses are a popular crop for both domestic and commercial cut flowers. Generally they are harvested and cut when in bud, and held in refrigerated conditions until ready for display at their point of sale.
In temperate climates, cut roses are often grown in greenhouses, and in warmer countries they may also be grown under cover in order to ensure that the flowers are not damaged by weather and that pest and disease control can be carried out effectively. Significant quantities are grown in some tropical countries, and these are shipped by air to markets across the world.
Some kind of roses are artificially coloured using dyed water, like rainbow roses.
Rose perfumes are made from rose oil (also called attar of roses), which is a mixture of volatile essential oils obtained by steam distilling the crushed petals of roses. An associated product is rose water which is used for cooking, cosmetics, medicine and religious practices. The production technique originated in Persiaand then spread through Arabia and India, and more recently into eastern Europe. In Bulgaria, Iran and Germany, damask roses (Rosa × damascena 'Trigintipetala') are used. In other parts of the world Rosa × centifolia is commonly used. The oil is transparent pale yellow or yellow-grey in colour. 'Rose Absolute' is solvent-extracted with hexane and produces a darker oil, dark yellow to orange in colour. The weight of oil extracted is about one three-thousandth to one six-thousandth of the weight of the flowers; for example, about two thousand flowers are required to produce one gram of oil.
The main constituents of attar of roses are the fragrant alcohols geraniol and L-citronellol and rose camphor, an odorless solid composed of alkanes, which separates from rose oil.β-Damascenone is also a significant contributor to the scent.
Rose hips are high in vitamin C, are edible raw,and occasionally made into jam, jelly, marmalade, and soup, or are brewed for tea. They are also pressed and filtered to make rose hip syrup. Rose hips are also used to produce rose hip seed oil, which is used in skin products and some makeup products.
Rose water has a very distinctive flavour and is used in Middle Eastern, Persian, and South Asian cuisine—especially in sweets such as Turkish delight,barfi, baklava, halva, gulab jamun, knafeh, and nougat. Rose petals or flower buds are sometimes used to flavour ordinary tea, or combined with other herbs to make herbal teas. A sweet preserve of rose petals called gulkand is common in the Indian subcontinent. The leaves and washed roots are also sometimes used to make tea.
In France, there is much use of rose syrup, most commonly made from an extract of rose petals. In the Indian subcontinent, Rooh Afza, a concentrated squash made with roses, is popular, as are rose-flavoured frozen desserts such as ice cream and kulfi.
The flower stems and young shoots are edible, as are the petals (sans the white or green bases).The latter are usually used as flavouring or to add their scent to food. Other minor uses include candied rose petals.
Rose creams (rose-flavoured fondant covered in chocolate, often topped with a crystallised rose petal) are a traditional English confectionery widely available from numerous producers in the UK.
Under the American Federal Food, Drug, and Cosmetic Act,there are only certain Rosa species, varieties, and parts are listed as generally recognized as safe (GRAS).
The rose hip, usually from R. canina, is used as a minor source of vitamin C.Diarrhodon (Gr διάρροδον, "compound of roses", from ῥόδων, "of roses" ) is a name given to various compounds in which red roses are an ingredient.
The long cultural history of the rose has led to it being used often as a symbol. In ancient Greece, the rose was closely associated with the goddess Aphrodite.In the Iliad , Aphrodite protects the body of Hector using the "immortal oil of the rose" and the archaic Greek lyric poet Ibycus praises a beautiful youth saying that Aphrodite nursed him "among rose blossoms". The second-century AD Greek travel writer Pausanias associates the rose with the story of Adonis and states that the rose is red because Aphrodite wounded herself on one of its thorns and stained the flower red with her blood. Book Eleven of the ancient Roman novel The Golden Ass by Apuleius contains a scene in which the goddess Isis, who is identified with Venus, instructs the main character, Lucius, who has been transformed into a donkey, to eat rose petals from a crown of roses worn by a priest as part of a religious procession in order to regain his humanity. French writer René Rapin invented a myth in which a beautiful Corinthian queen named Rhodanthe ("she with rose flowers") was besieged inside a temple of Artemis by three ardent suitors who wished to worship her as a goddess; the god Apollo then transformed her into a rosebush.
Following the Christianization of the Roman Empire, the rose became identified with the Virgin Mary. The colour of the rose and the number of roses received has symbolic representation.The rose symbol eventually led to the creation of the rosary and other devotional prayers in Christianity.
Ever since the 1400s, the Franciscans have had a Crown Rosary of the Seven Joys of the Blessed Virgin Mary.In the 1400s and 1500s, the Carthusians promoted the idea of sacred mysteries associated with the rose symbol and rose gardens. Albrecht Dürer's painting The Feast of the Rosary (1506) depicts the Virgin Mary distributing garlands of roses to her worshippers.
Roses symbolised the Houses of York and Lancaster in a conflict known as the Wars of the Roses.
Roses are a favored subject in art and appear in portraits, illustrations, on stamps, as ornaments or as architectural elements. The Luxembourg-born Belgian artist and botanist Pierre-Joseph Redouté is known for his detailed watercolours of flowers, particularly roses.
Henri Fantin-Latour was also a prolific painter of still life, particularly flowers including roses. The rose 'Fantin-Latour' was named after the artist.
Other impressionists including Claude Monet, Paul Cézanne and Pierre-Auguste Renoir have paintings of roses among their works. In the 19th century, for example, artists associated the city of Trieste with a certain rare white rose, and this rose developed as the city's symbol. It was not until 2021 that the rose, which was believed to be extinct, was rediscovered there.
In 1986 President Ronald Reagan signed legislation to make the rosethe floral emblem of the United States.
Wild roses are host plants for a number of pests and diseases. Many of these affect other plants, including other genera of the Rosaceae.
Cultivated roses are often subject to severe damage from insect, arachnid and fungal pests and diseases. In many cases they cannot be usefully grown without regular treatment to control these problems.
Camellia is a genus of flowering plants in the family Theaceae. They are found in tropical and subtropical areas in eastern and southern Asia, from the Himalayas east to Japan and Indonesia. There are more than 220 described species. Camellias are popular ornamental, tea and woody-oil plants that have been cultivated throughout the world for centuries. To date, over 26,000 cultivars, with more than 51,000 cultivar names including synonyms, have been registered or published.
Rosa rugosa is a species of rose native to eastern Asia, in northeastern China, Japan, Korea and southeastern Siberia, where it grows on beach coasts, often on sand dunes.

Rosa minutifolia is a species in the genus Rosa. It is also known by the common names Baja rose, Baja littleleaf rose, and small-leaved rose.
Garden roses are predominantly hybrid roses that are grown as ornamental plants in private or public gardens. They are one of the most popular and widely cultivated groups of flowering plants, especially in temperate climates. An enormous number of garden cultivars have been produced, especially over the last two centuries, though roses have been known in the garden for millennia beforehand. While most garden roses are grown for their flowers, often in dedicated rose gardens, some are also valued for other reasons, such as having ornamental fruit, providing ground cover, or for hedging.
Rosa 'Cécile Brünner', also known as 'Mlle Cécile Brünner', 'Sweetheart Rose', 'Malteser Rose', or 'Mignon', is a light pink polyantha rose bred in France by Marie Ducher and introduced by her son-in-law, Joseph Pernet-Ducher in 1881. Its parents were a double-flowered R. multiflora and a hybrid tea rose, either 'Souvenir d'un Ami' or a seedling of 'Mme de Tartas'. It is not clear if the rose was named after the sister (1853–1927) or daughter of Ulrich Brunner fils.
