Blackberry: Identification and Management in Pasture and Rangeland
Blackberry (Rubus sp.) are native (usually) woody shrubs or brambles. They are members of the Rosaceae, or rose family, which includes over 600 species and developed varieties of blackberries, raspberries and dewberries in the Rubus genus. Many improved varieties of blackberry have been developed by plant breeders, and blackberry species readily hybridize, so some species can be difficult to differentiate and there can be large differences between species.
