Rugosa rose is a shrub from eastern Asia that has escaped cultivation along parts of the U.S. Atlantic coast. Its deeply wrinkled leaves, densely prickly stems, and large, round red fruits help distinguish it from other roses. It is also commonly called beach rose.

Rugosa rose has large pink flowers, large round hips, deeply wrinkled leaves, and dense straight prickles. Multiflora rose has clusters of many small white flowers and fringed at the base of each leaf stalk.
