Blackberry Triple Crown is one of the best blackberries for the home garden because of its three outstanding attributes: excellent flavor, productivity and vigor. It has a long fruiting season that starts in late summer and continues for 4-6 weeks. The sweet, juicy berries are huge and plentiful and provide the gardener with lots of tasty fruit for eating fresh or freezing for later use. The thornless aspect of Triple Crown is a significant benefit since picking standard blackberries can leave you with deep scratches. Blackberries are biennial plants. Canes grow one year and fruit the next. In the fall, once fruiting is done, cut out the old canes to keep your bed clean and tidy. Triple Crown is self-fertile so you only need one plant to enjoy these delicious blackberries, but youll probably want to plant more! Blackberries are a healthy fruit rich in beneficial vitamins and minerals, fiber and antioxidants.
