Rosa gymnocarpa is a species of rose native to western North America. It is known by the common names dwarf rose, [1] baldhip rose, and wood rose. It grows in shady, damp, and rich forests.
Rosa gymnocarpa is a perennial [2] shrub growing up to 2 metres (6.6 ft) in height. Its stem is covered with long, straight spines which may or may not be abundant.
The pink or white fragrant flowers are flat and open-faced with five petals in most any shade of pink to almost lavender. Its fruit is a red rose hip containing hard tan achenes that contain the seeds. The sepals fall away from the hip earlier than in other species of rose, hence the name baldhip rose. The leaves are pinnately compound, alternate, with 5 to 9 leaflets, each of which are 1 to 4 cm. Leaflets are elliptic to ovate to round. [3]
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.
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.
Rosa rubiginosa is a species of rose native to Europe and western Asia.
Rosa arkansana, the prairie rose or wild prairie rose, is a species of rose native to a large area of central North America, between the Appalachian and Rocky Mountains from Alberta, Manitoba, and Saskatchewan south to New Mexico, Texas and Indiana. There are two varieties:

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.

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.
Rosa virginiana, commonly known as the Virginia rose, common wild rose or prairie rose, is a woody perennial in the rose family native to eastern North America, where it is the most common wild rose. It is deciduous, forming a suckering shrub up to 2 metres in height, though often less. The stems are covered in numerous hooked prickles. The leaves are pinnate, usually with between 7 and 9 glossy leaflets. The pink flowers are borne singly or in small clusters and appear over a long period in midsummer. The fruits are small, round and bright red, rich in vitamin C and edible, being both used to make jams and tea. It grows in clearings, thickets, and shores. The plant attracts birds, bees, butterflies, and hummingbirds.
Rosa carolina, commonly known as the Carolina rose, pasture rose, or prairie rose, is a perennial shrub in the rose family native to eastern North America. It can be found in nearly all US states and Canadian provinces east of the Great Plains. It is common throughout its range and can be found in a wide variety of open habitats, from thickets and open woods to roadsides and along railroads.
Rosa californica, the California wildrose, or California rose, is a species of rose native to the U.S. states of California and Oregon and the northern part of Baja California, Mexico. The plant is native to chaparral and woodlands and the Sierra Nevada foothills, and can survive drought, though it grows most abundantly in moist soils near water sources.

Rosa bridgesii is a species of rose known by the common names pygmy rose and Sierran dwarf rose. It is native to California, where it grows in the forests of the Sierra Nevada and surrounding mountains and foothills. It may also occur in Oregon.
Rosa pisocarpa is a species of rose known by the common name cluster rose or swamp rose. It is native to western North America from British Columbia to northern California, where it generally grows in moist habitats. It is a shrub sometimes forming a thicket, and growing up to 2.5 meters tall. The stems can be dark red or blackish and are often studded with straight, paired prickles at nodes. The leaves are each made up of several toothed oval leaflets, the terminal leaflet up to 4 centimeters long. The inflorescence is a cyme of up to 10 flowers with pink petals each up to 2 centimeters in length. The fruit is a rose hip about a centimeter wide. The hips are pear- or egg-shaped and borne in clusters, and are decorative in fall and early winter, when they are red or reddish-purple and contrast with yellow foliage. Fall foliage can be yellow or dark red.
Rosa spithamea is a species of rose known by the common names ground rose and coast ground rose. It is native to Oregon and California, where it grows in forest and chaparral habitats, especially areas recently burned.

Rosa willmottiae, Miss Willmott's rose or Willmott's rose, is a species in the genus Rosa in the plant family Rosaceae. It grows at an altitude of 2,300–3,150 metres (7,550–10,330 ft) in dry valleys in western Sichuan, China. It forms an arching deciduous shrub 2–3 m high, and as much across. The branches are covered in many straight prickles. The pinnate leaves typically have 7 to 9 small bluish-green leaflets which emit a pleasant fragrance when bruised. It was introduced to western cultivation by Ernest Wilson in 1904 and was named after the collector and horticulturist Ellen Willmott. The flowers are small, lilac-pink, and are borne on short laterals all along the length of the branches in late spring/early summer. The hips are small, becoming orange-red and losing their tips when ripe.
Rosa nitida, also known as the shining rose due to its glossy leaves, is a perennial species in the plant genus Rosa in the plant family Rosaceae. It is native to northeastern North America, from Connecticut north to Newfoundland and Quebec. It forms a low, suckering, deciduous shrub, growing up to a metre in height, although often less. Its stems are thin and covered in fine bristles. Its pinnate leaves have 7 to 9 shining leaflets which turn bright red, yellow and purple in the fall. Its small pink flowers appear in summer and are subtly but sweetly scented, smelling like Convallaria ("Lily-of-the-Valley"). They are followed by small, round, red hips.
