Rubus strigosus: foliage showing the large leaf of a first-year shoot, and the smaller leaves of a second-year shoot
Rubus strigosus, the American red raspberry or American raspberry, is a species of Rubus native to much of North America. It was often treated as a variety or subspecies of the closely related Eurasian Rubus idaeus (red raspberry or European red raspberry),[1][2] but is now more commonly treated as a distinct species.[3][4][5] Many of the commercial raspberry cultivars grown for their fruit derive from hybrids between R. strigosus and R. idaeus; see Raspberry for more details.
