Rosaceae

Rubus discolor

Himalayan Blackberry

Sprawling to arching bramble, stems often reaching 30 ft. in length. Stems 5-angled, armed with many curved thorns with stout broad base. Leaves often more or less evergreen, divided palmately, 3–5 leaflets widest at the middle, sharply toothed, white on underside. Flowers numerous, clustered white or pink. Fruit shiny, black, with many small sections forming an oval to round berry. Invasive in disturbed moist areas along roads, ditches, and fences at low to mid-elevations, this is our common and very tasty introduced blackberry. Native to Europe and Asia. Compare to R. laciniatus, also invasive, with similar growth habit and fruit but deeply cut leaves.
