Back to Full ListCutleaf Blackberry
Latin Name: Rubus laciniatus
Identification
Flower: White or pinkish, five-petaled flowers that bloom in late spring to early summer.
Leaves: Deeply lobed, serrated, and dark green, with a characteristic cutleaf appearance.
Stems: Arching, thorny, and sprawling, growing up to 3 meters long.
Growing Environment: It prefers moist semi-arid climates. It is often found riparian areas and in disturbed areas, forests and roadsides.
Growth Habit: A perennial, thorny shrub that spreads through both seeds and long, arching stems that root at the tips. It forms dense, impenetrable thickets, often sprawling over other vegetation. In situ, Cutleaf blackberry appears as large, tangled masses of thorny stems and foliage that can cover vast areas, particularly in open or disturbed habitats.
Impacts on Environment
Impacts: Highly invasive. It out competes native vegetation and reduces biodiversity. Infests stream channels and banks, restricts wildlife passage, and increases stream bank erosion.
