How to Start It
★ Recommended for beginners
Bury the tip of a trailing cane in soil in late summer; it roots into a new plant you can sever and move.
A trailing blackberry × raspberry hybrid with big, soft, wine-coloured berries. Self-fertile, but a touch less hardy than blackberries (to about -18°C). It fruits on second-year canes, so train the new canes separately and remove the old ones after fruiting.
