'Brandywine' purple raspberry
The purple raspberry is a hybrid between the red raspberry, Rubus ideaus strigosus, and the black raspberry, Rubus occidentalis. In many breeding programs, crosses have been made between the various colored fruited clones resulting in selections with complex parentages. Some seedlings closely resemble the red raspberry and produce suckers while others more closely resemble the black raspberry and are propagated by tip-layering.
