Himalayan Blackberry Armenian Blackberry

Himalayan blackberry is an extremely vigorous, dense, thornbeach-covered shrub that can reach 10 feet, though it is often encountered as a sprawling cane thicket. Though commonly called Himalayan blackberry, the plant actually originates from western Europe (not the Himalayas) and has naturalized aggressively throughout disturbed areas of the Pacific Northwest.

Himalayan blackberry is considered highly invasive throughout the region; it tolerates poor soils, standing water, and neglect. The plant spreads explosively through rooted runners, layering canes, and bird-dispersed seed. Control in natural areas requires persistent effort: repeated mowing or cutting, careful selective herbicide application, or biological approaches.
