Rosaceae, the rose family, is a medium-sized family of flowering plants that includes 4,828 known species in 91 genera.
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. 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.
Rubus is a large and diverse genus of flowering plants in the rose family, Rosaceae, subfamily Rosoideae, with over 1,350 species, commonly known as brambles.
Amelanchier, also known as shadbush, shadwood or shadblow, serviceberry or sarvisberry, juneberry, saskatoon, sugarplum, wild-plum or chuckley pear, is a genus of about 20 species of deciduous-leaved shrubs and small trees in the rose family (Rosaceae).
Potentilla is a genus containing over 300 species of annual, biennial and perennial herbaceous flowering plants in the rose family, Rosaceae.
Rosa multiflora is a species of rose known commonly as multiflora rose, baby rose, Japanese rose, many-flowered rose, seven-sisters rose, Eijitsu rose and rambler rose. It is native to eastern Asia, in China, Japan, and Korea. It should not be confused with Rosa rugosa, which is also known as "Japanese rose", or with polyantha roses which are garden cultivars derived from hybrids of R. multiflora. It was introduced to North America, where it is regarded as an invasive species.
Chamaemespilus is a genus of shrubs in the family Rosaceae. It is monotypic, being represented by the single species Chamaemespilus alpina, commonly known as false medlar or dwarf whitebeam. It is native to the mountains of central and southern Europe, from the Pyrenees east through the Alps to the Carpathians and the Balkans, growing at altitudes of up to 2500 m.
Salix babylonica is a species of willow native to dry areas of northern China, but cultivated for millennia elsewhere in Asia, being traded along the Silk Road to southwest Asia and Europe.
Calycanthus, called sweetshrub, is a genus of flowering plants in the family Calycanthaceae. The genus includes two to four species depending on taxonomic interpretation; three are accepted by most 21st century sources.
Rosa chinensis, known commonly as the China rose, Chinese rose, or Bengal rose, is a member of the genus Rosa native to Southwest China in Guizhou, Hubei, and Sichuan Provinces. The first publication of Rosa chinensis was in 1768 by Nikolaus Joseph von Jacquin in Observationum Botanicarum, 3, p. 7 & plate 55.
Rosa moyesii is a species of flowering plant in the rose family Rosaceae, native to western China. Growing to 4 m (13 ft) tall by 3 m (10 ft) wide, it is a vigorous deciduous shrub, with plentiful matte green leaves and flat red or pink flowers, with yellow central stamens, in summer. These are followed in autumn (fall) by prominent bottle-shaped rose-hips.
Rosa majalis is a species of deciduous shrubs in the genus Rosa, native to forests of Europe and Siberia. It grows to 2 m. and yields edible hip fruits rich in vitamin C, which are used in medicine and to produce rose hip syrup.
Rosa 'Zephirine Drouhin' is a cherry-pink Bourbon rose, famous for being completely thornless. It was developed by French rose breeder, Bizot, in 1868. Its origin is unknown, although believed to be the outcome of a cross between a Boursault rose and a Hybrid Perpetual rose. The new rose cultivar was first introduced in Switzerland by the horticulturalist Charles Bonnet, who sold it under his own name in 1868. It was later introduced in Australia by Hazlewood Bros. Pty. Ltd. in before 1921 as 'Zéphirine Drouhin'.
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 × odorata or Rosa odorata is a hybrid flowering plant of the genus Rosa native to Yunnan in southwest China, whose taxonomy has been confused. It has been considered a hybrid of Rosa gigantea and Rosa chinensis, or as a quite rare wild species that includes R. gigantea. The wild forms are cultivated to some extent. Cultivars were developed in China in ancient times from R. chinensis crosses, and these have been important in the ancestry of the tea-scented China roses, also called tea roses, and their descendants the hybrid tea roses.
Rosa × alba, the white rose of York, is a hybrid rose of unknown parentage that has been cultivated in Europe since ancient times. It may have originally been grown mainly for the sweet scent of the flowers, but is now also used as a winter-hardy garden shrub. Cultivated forms have white or pink flowers, and most have many petals. Hybrid cultivars have also been produced with red or yellow flowers.
Rosa tomentosa, otherwise known as the harsh downy-rose, is a species of wild rose. It is a shrub growing to about 3 metres (10 ft). It is found in Asia Minor, the Caucasus, and much of Europe: the British Isles, France, Central Europe, northern Spain, Italy, and the Balkans . On the British Isles it can be found in hedgerows and woodland margins, and it typically flowers between June and July. Further south, in Bulgaria, it flowers in May.
Rosa oxyodon is a species of wild rose native to the Caucasus. It is closely related to Rosa pendulina.
