Thornless Blackberry Triple Crown Bushes
The Triple Crown Blackberry Plants are the newest thornless blackberry. The Triple Crown Blackberry is named for its three crowning attributes: flavor - productivity - vigor.
Excitement begins when the Triple Crown Blackberry bushes ripen from roughly July 10 to about August 10 in most areas. This thornless blackberry variety yields large, glossy black fruits that are firm and have the capacity to produce larger berries than any other variety that we have seen.
Agriculture research scientists tested the Triple Crown Blackberry plant for a decade before releasing it in 1996. The thornless Triple Crown Blackberry is well suited to berry farms, pick-your-own operations and backyard home gardens. It should help ensure a steady mid-summer supply of large, flavorful berries for fresh eating and storing.
In Oregon trials, 8-year-old Triple Crown Blackberry plants yielded an impressive 30 pounds or more of blackberries per plant. Puree tests by ARS and Oregon State University scientists determined that the blackberry is also suitable for juice, pies, syrup, preserves and other processed foods. Triple Crown rated equal to the popular Chester Thornless and Marion blackberries in color, flavor and overall quality.
The semi-erect nature of the Triple Crown Blackberry is similar to a trailing berry plantand requires trellising for optimum production. Once the canes reach about 30 inches, they begin to fall over to the ground. This plant like most trailing varieties is propagated through tip layering. It will not be as long and dense as the upright varieties which are 2 year old plants.
