This sweet thornless blackberry owes its 'Triple Crown' moniker to its three crowning attributes – excellent flavor, productivity and vigor! The jumbo-sized blackberries are firm and glossy, and as big as a quarter, sometimes larger. They're the best-tasting blackberry we've tried and have a wonderfully complex sweet flavor with no hint of the acidic tang that's present in other varieties. Triple Crown is also thornless—so picking is easy. Triple Crown begins to ripen in mid-July. The self-pollinating plants grow into 12- 15 ft., semi-erect canes with dense foliage that offers protection against sun scald. Zones 5-9.
