Hybrid berries (also termed rubus hybrids) are the result of crossing between various Rubus species, typically Blackberries, Raspberries and Dewberries. The fruit resemble Blackberries but are larger, longer and slightly redder. Each hybrid has a distinctive flavour and can be grown in the same way as Blackberries, fan-trained on horizontal wires supported by posts. This article has more information about this training method:  Hybrid berries have perennial root systems and biennial stems which fruit in the second growing season. In the first year the shoots, termed canes are vigorous, long arching stems. In the second growing season, most hybrid berries put out side shoots from the cane which flower and bear fruit. Most hybrid berries crop in this manner are termed "floricanes". Those few that fruit in the first year are termed "primocanes".

Introduced in 1979 by Dr. D. Jennings, and named after the River Tay in Scotland. Hybrid between the American blackberry cultivar "Aurora" and raspberry. Essentially an improved version of the Loganberry, and some say, the best hybrid berry. A chance mutation in 1998 resulted in a spine-free version (Buckingham Tayberry), now the main form grown. Tayberry received the "Award of Garden Merit" by the Royal Horticultural Society.
