The Triple Crown
This is a semi-trailing, thorn-less blackberry vine with medium to large, flavorful berries. Its dense foliage helps to prevent sun-scald. The blackberry can be grown as a bush or as vine depending on pruning technique. The vigorous vines grow up to 15 feet long and do require support. Triple Crown is very productive, produces reliable harvests, and is a widely adapted, excellent home garden variety.
