Family Rosaceae

Rubus fruticosus ‘Triple Crown’ is a thornless blackberry known for its exceptional vigor and the remarkable quality of its fruit. This semi-erect, bushy fruit shrub develops long, robust canes, making it easy to grow on a trellis. It produces very large, shiny black fruits that are firm, juicy, and intensely sweet, perfect for fresh consumption, jams, and summer desserts. Its abundant fruiting occurs in late summer, extending the berry season in the garden. Its dense green foliage creates a beautiful green screen while attracting pollinators. Ideal for fruit hedges, structured rows, or edible beds, Rubus fruticosus ‘Triple Crown’ combines high yield, excellent flavor, and simplified cultivation thanks to its thornless nature.
