Himalayan blackberry is a perennial shrub native to Eurasia. Stems grow to 15 ft. (4.6 m) before arching and then trailing over the ground for up to 40 ft. (12.2 m). As stems touch the ground they root at the nodes, producing a dense thicket. The leaves of the prima cane (first year shoots) are 2.8-7.9 in. (7-20 cm) long and palmately compound with 5 leaflets. No flowers are produced on the first year’s growth. In the second year several side shoots are produced (flora canes) having smaller leaves with 3 leaflets. The leaflets are oval and toothed with thorns along the underside of the mid-rib. Flowering occurs in late spring to early summer; when white to pale pink flowers develop on the flora canes. Flowers have 5 petals, numerous stamens and are 0.8-1 in. (2-2.5 cm) in diameter. Fruits are an aggregate of drupelets that are black, when mature, and 0.5-0.8 in. (1.2-2 cm) in diameter. Himalayan blackberry was introduced into North America in 1885 as a cultivated crop and occurs in pastures, riparian areas, wastelands, fence lines and right-of-ways. |
