The sweetly scented flowers are used to make pot-pourri in Japan and China, where it has been cultivated for about a thousand years. It is a suckering shrub which develops new plants from the roots and forms dense thickets 1 to 1.50 m tall with stems densely covered in numerous short, straight prickles 3 to 10 mm long. The leaves are 8 to 15 cm long, pinnate with 5 to 9 leaflets, most often 7, each leaflet 3 to 4 cm long, with a distinctly corrugated (rugose, hence the species' name) surface. The flowers are pleasantly scented, dark pink to white, 6 to 9 cm across, with somewhat wrinkled petals. The hips are large, 2 to 3 cm diameter, and often shorter than their diameter, not elongated.
Rugosa rose is widely used as an ornamental plant. It has been introduced to numerous areas of Europe and North America. It is also found near beaches. Flowering begins in spring. In late summer and early autumn the plants often bear fruit and flowers at the same time.
