Rosa rugosa is a deciduous bush, 1-1.5m in height, inhabiting sandy soil in a coastal area, reportedly from Hokkaido to Shimane. The rhizomes extend to make shoots and grow in bundles, forming colonies. There are many pubescent and stickles mingling with each other, and the stickles also have densely short hairs. Leaves are of alternate phyllotaxis and are of odd-pinnate compound leaves with3-4 pairs of leaflets. The lobes are oblong or oval-oblong, tips round, the bases wedge-shaped or circular, and margins bluntly serrated. Flowers, bright red to red-purple, 1-3 in number, each 5-8cm in diameter, come on the tips of branches. Bloom time: May-August.
