Rubus fruticosus 'Darrow' is a hardy blackberry known for its cold tolerance and reliable production in northern climates. This semi-erect bushy fruit shrub develops vigorous thorny canes, ideal for row or trellis cultivation. It produces large, firm, juicy, and pleasantly sweet shiny black fruits, perfect for fresh consumption, jams, and processing. Its summer fruiting, on previous year's canes, offers an abundant mid-season harvest. Its dense green foliage attracts pollinators and contributes to the garden's nutritional interest. Rubus fruticosus 'Darrow' combines robustness, good adaptation to cold winters, and consistent yields for productive gardens.
