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.
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. It should not be confused with Rosa multiflora, which is also known as "Japanese rose". The Latin word "rugosa" means "wrinkled", referring to the wrinkled leaves. Often used as an ornamental plant, it has become invasive in parts of Europe, North America and South America.
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.
Hibiscus rosa-sinensis, known colloquially as Chinese hibiscus, China rose, Hawaiian hibiscus, rose mallow and shoeblack plant, is a species of tropical hibiscus, a flowering plant in the Hibisceae tribe of the family Malvaceae. It is widely cultivated as an ornamental plant in the tropics and subtropics, but its native range is Vanuatu.
Rosa canina, commonly known as the dog rose, is a variable climbing, wild rose species native to Europe, northwest Africa, and western Asia.
Rosa banksiae, common names Lady Banks' rose, or just Banks' rose, is a species of flowering plant in the rose family, native to central and western China, in the provinces of Gansu, Guizhou, Henan, Hubei, Jiangsu, Sichuan and Yunnan, at altitudes of 500–2,200 m (1,640–7,218 ft). The rose is named for Dorothea Lady Banks, the wife of the botanist Sir Joseph Banks.
Rosa nutkana, the Nootka rose, bristly rose, or wild rose is a 0.6–3.0-metre-tall (2–10-foot) perennial shrub in the rose family (Rosaceae).
Rosa × damascena, more commonly known as the Damask rose, or sometimes as the Iranian Rose, Bulgarian rose, Arab rose, Ispahan rose and Castile rose, is a rose hybrid, derived from Rosa gallica and Rosa moschata. DNA analysis has shown that a third species, Rosa fedtschenkoana, has made some genetic contributions to the Damask rose.
Rosa pimpinellifolia, the burnet rose, is a species of rose native to western, central and southern Europe and northwest Africa.
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 acicularis is a flowering plant in the Rosaceae family. It is commonly known as the prickly wild rose, prickly rose, bristly rose, wild rose or Arctic rose. It is a species of wild rose with a Holarctic distribution in northern regions of Asia, Europe, and North America.
A haor is a wetland ecosystem in the north eastern part of Bangladesh which physically is a bowl or saucer shaped shallow depression, also known as a backswamp. During monsoons haors receive surface runoff water from rivers and canals to become vast stretches of turbulent water.
Rosa sempervirens, the evergreen rose, is a species of wild rose native to the Mediterranean. It is a climbing perennial with very prickly stems.
Rosa persica is an anomalous species of rose that at one time was placed in a separate genus Hulthemia. It is native to deserts and steppes from Iran and Afghanistan in the south, through Central Asia, to western Siberia in the north. Its distinctive characteristics include a simple leaf without stipules, and a distinctive flower with a darker coloured central zone. In its natural habitat it is a deep-rooted weed that suckers – growing in Iranian fields for example, where it is collected for fuel once the grain crop has been harvested – but it is difficult to grow in gardens and rarely cultivated.
Rosa arvensis, the field rose, is a species of wild rose native to Western, Central and Southern Europe.
Rosa pendulina,, the Alpine rose or mountain rose, is a species of wild rose found in the mountains of central and southern Europe. It appears to have survived in glacial refugia in the Alps and Carpathians, and spread out from there. A climbing shrub with deep pink flowers and relatively few thorns, it has had a history of cultivation as an ornamental plant.
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 beggeriana is a species of rose found in Anatolia, Iran, Afghanistan, Pakistan, all of Central Asia, Xinjiang and Gansu in China, and Mongolia. It is a winter‑hardy rambler, with typically flat white flowers, and small red hips. Its 'Polstjärnan' (polestar) cultivar is the cold‑hardiest known climbing rose.
Rosa webbiana, occasionally called Webb's rose, wild rose, or thorny rose, is a widely distributed species of flowering plant in the family Rosaceae. It is native to Central Asia, Tibet and Xinjiang in China, Afghanistan, Pakistan, the western Himalayas, and Nepal. It grows in scrub, grassy places, valleys, and slopes. A diploid, its chromosome count is 2n = 2x = 14.
