Carolina rose

Scientific name: Rosa carolina L.

Common names: Carolina rose, pasture rose, swamp rose (regional use may vary)

Family: Rosaceae

Genus: Rosa

Rosa carolina is a member of the wild roses (genus Rosa) and is taxonomically allied with other native simple-rose species of eastern North America.

Carolina rose is a low to medium-sized, deciduous shrub that often forms loose, suckering colonies. Stems are typically slender and bear straight, sharp prickles rather than dense hooked thorns. Flowers are single and showy, usually pink to light pink, with generally 4–6 petals arranged around a prominent cluster of yellow stamens; blooms are borne singly or in small clusters. Leaves are pinnate, commonly with several (often 5–7) sharply toothed leaflets and paired stipules at the base of the petiole. After flowering the plant produces small, rounded to ovoid rose hips that turn red to orange and often persist into fall. Seasonal variation includes spring–summer flowering followed by summer–fall development of hips; foliage turns and drops in autumn as the plant goes dormant.

Carolina rose typically occurs in open woods, thickets, fields, roadsides, clearings and along forest edges. It often favors well-drained, sandy to rocky soils but can be found across a range of soil types from dry to mesic sites. The species tolerates full sun to partial shade and is commonly found in disturbed as well as semi-natural habitats. Geographically it is native to much of eastern North America, including the provided states (AL, AR, CT, DE, FL) and numerous additional states and provinces throughout the region.

Flowers attract a variety of insect pollinators, especially bees, which visit for pollen and nectar. The persistent hips are a food source for birds and small mammals, which help disperse seeds. Dense patches formed by suckering stems can provide protective cover and nesting shelter for small wildlife. The combination of prickles and flexible stems can deter some large herbivores while allowing regrowth from roots and stems.

Rose hips of wild roses, including Carolina rose, are edible and have been used traditionally for teas, preserves and as a food resource; they are also noted for containing nutrients typical of rose hips. Stems and hips have appeared in folk remedies and local uses, though specific ethnobotanical details vary regionally. Plants are non-toxic in the usual sense, but stems bear sharp prickles that can scratch skin.

Carolina rose is generally common across much of its range and is not widely considered at risk. A notable adaptation is its suckering habit, which allows rapid colonization of open ground and persistence after cutting or browsing. The simple, open flowers make the species a reliable attractor of native bees and other pollinators.
