Rosa rugosa / Hamanasu ハマナス


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. Many pubescent and stickles mingle, and the stickles also have densely short hairs. Leaves are alternate, odd-pinnate compound leaves with 3-4 pairs of leaflets. The lobes are oblong or oval-oblong, the tips round, the bases wedge-shaped or circular, and the 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.
