Rosa
rugosa is a deciduous shrub, 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, appear at the tips of the branches. Bloom time:
May-August. |
