Rubus crataegifolius (fruit) / Kumaichigo クマイチゴ

Rubus crataegifolius is a deciduous shrub in sunny forest edges or wastelands in mountainous regions, growing to 1-2m in height, with flat, fat, straight prickles on stems and branches. Leaves are alternate, blades measuring 6-10cm in length, in the shape of a broad ovate, palmately cleft in 3-5; tips of the segments pointed, bases heart-shaped, and margins are coarsely double-serrated. White flowers 1-1.5cm in diameter bloom in clusters of 2-6, and the petals are narrow, with gaps between them. Sepals are narrowly ovate, with dense vellus hairs on them, and the sepals bend backward. Peduncles are also with thick vellum coats. In July and August, multiple fruits, spherical and approximately 1 cm across, ripen to a deep red. Bloom time: May-July.
