Boysenberry Thornless Jewel™

White flowers appear in spring, followed by large firm conical dark red/black berries with an old-fashioned boysenberry flavour, juicy and sweet. Hybridberry Thornless Jewel™ is moderately vigorous with thornless canes. It is self-fertile and pollinated by insects and bees. Thornless Jewel™ is a Boysenberry cross and grows New Zealand wide.

Hybridberry Thornless Jewel™ should be ready for harvesting over December (early season) and is a heavy cropper. The best way to have Hybridberries is to eat fresh, straight from the plant. Or chilled for later use in desserts, added to a fresh summer salad or a bowl of ice-cream. The berries are ready when easily removed. Hybridberries are high in antioxidants, full of minerals and vitamins, and plenty of fibre.

Plant in full sun and protect from wind (including salty sea winds). Plant in a well-drained position with good moisture content and high in organic matter, as this will see the plant thrive. (Mulch annually in spring). Like any deciduous fruiting plant, they benefit from Copper and Oil sprays during winter to help keep the plant healthy and disease-free.

Pruning all brambles involves tying up strong canes produced in spring and summer and removing thin, weak, and wandering canes. In late summer - early autumn, remove 10cm of the terminal growth of the canes. This will initiate the production of fruiting spurs. Remove fruited canes from the soil base in autumn (or winter in cooler, dryer areas).
