Rosa carolina, commonly known as theCarolina rose,[2]pasture rose, orprairie rose, is a perennial shrub in therose family native to easternNorth America. It can be found in nearly allUS states andCanadian provinces east of theGreat 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 carolina is a perennial shrub.[3] The stems have straight, needle-like thorns, which distinguishes it from very similar species such asR. palustris andR. virginiana, which have curved thorns. The fragrant flowers emerge in early summer.[1] Blooms are about 6 to 8 centimeters (2.5 to 3 inches) in diameter, with five light pink petals and a yellow center. Flowers are typically borne singly on the ends of the current year's growth. There is no repeat bloom. The stems of the rose are upright, grayish in color on new growth, and brown on larger, older branches. Foliage is smooth and dark green. The plants proliferate by root spread. New growth will eventually become small to large thickets, anywhere from 0.5 to 1 m (18 to 40 inches) in height.[4][5]
This plant can be differentiated from other species of wild rose by its larger, pink flowers. They bloom later than many other species and for a shorter time. The shrub also tends to stay lower than other wild rose species. It's rosehips are round, large and have protrusions at the opposite end from the stem. Rosa Setigera, on the other hand, has small, round hips similar to Multiflora and can get large, but usually have a mix of pink and white flowers. Rosa Multiflora only has white flowers. Another invasive, Dog Rose, has pink flowers like setigera, but the hips are large and more cylindrical.
The Carolina rose is frequently found in a wide range of habitats, including dry soils, at the border ofprairies,woodlands, andsavannas, in thickets, in upland forested areas, anddunes. It also grows in wet soils along stream beds, swamps and low grassy areas. It has a wide range, fromNova Scotia,Canada, south toFlorida, west toTexas, and north toOntario.[4]
The Carolina rose can be cultivated. It needs full sun to moderate shade, well-drained soil and regular watering to thrive. Therose hips are edible, although very tart in flavor. The plant is attractive to several species of bees[4] and also provides nesting materials to them.[3]
