A rambling soft fruit, Boysenberry carries almost oblong fruit with all the flavour of a wild blackberry (although several times the size). They are quite vigorous and crop very heavily. A fairly complicated cross between loganberries, raspberries and dewberries, Boysenberries are immensely hardy. They are also even more resistant to disease and drought than blackberries. They produce a large dark fruit that tastes of a wild blackberry.
