Originating from the famous Knott's Berry Farm in California, the superb hybrid Rubus ursinus x. idaeus Boysenberry is a complicated cross between a blackberry, loganberry, dewberry and raspberry! It is vigorous and a prolific cropper. White flowers in early spring are followed by large firm conical dark purple blackberries. The fruit is round to oblong in shape and dark purple in colour. They have a unique flavour that combines the tartness from good old-fashioned wild blackberries with a sweet hint of raspberry. Train on wires as you would raspberries, as a fan, or even over an arch. Prune after harvesting in summer or autumn, by cutting the fruited canes down to the ground. When the new canes start growing the following spring and summer, tie them onto their supports. Self-fertile
