R. davurica var. alpestris is found in grassland and on forest margins in Hokkaido, and in some limited areas of central Honshu: Gunma and Nagano Prefectures. The flowers of this rose closely resembles that of R. rugosa, though it is a little smaller (3 to 4 cm across). Two, three, or more flowers are borne at the terminal of a small cane. The tree grows pretty tall, some reaching 2 metres or more. Its distinctive features are purplish coloured stems and reddish bracts at the base of a peduncle. It gives globular or ovoid fruits ca. 12 mm across. Its flowering period in C-Honshu is the beginning of July. Its fragrance is spicy, too, but less sweet than that of R. rugosa.
