Cutleaf Blackberry is a European introduction naturalized across much of the Pacific Coast and parts of the eastern United States, immediately recognizable by its deeply dissected, fernlike leaflets that set it apart from other brambles. It is a vigorous, invasive scrambler that forms dense impenetrable thickets on roadsides, disturbed ground, and forest margins. Despite its invasive status, it produces abundant, large, sweet-tart berries that are eagerly consumed by wildlife and human foragers alike. It is especially abundant in the Pacific Northwest, where it often grows alongside the even more aggressive Himalayan Blackberry.
