Rubus corchorifolius / Birohdoichigo ビロードイチゴ

Rubus corchorifolius is a deciduous shrub that inhabits forest edges in mountainous regions, exhibiting various forms, including standing and crawling. New branches wear dense, velvety hairs but disappear at a particular stage. Leaves are of alternate phyllotaxis, and blades measure 4-10cm in length, in the shape of a broad ovate, occasionally cleft in three, with sharply serrated margins. White flowers, 1.5-2cm in diameter, bloom facing downwards on short sprigs that emerged from the previous year's branches. Dense, velvety hairs exist on petioles and sepals. Bloom time: April-May.
