Tayberry (Rubus fruticosus x R. idaeus) is a cultivated shrub in the genus Rubus of the family Rosaceae patented in 1979 as a cross between a blackberry and a red raspberry, and named after the river Tay in Scotland. The fruit is sweeter, much larger, and more aromatic than that of the loganberry, itself a blackberry and red raspberry cross.
