Rubus fruticosus 'Columbia Giant' is an exceptionally productive thornless blackberry, renowned for the impressive size of its fruits. This bushy, trailing fruit shrub develops long, vigorous canes ideal for trellis cultivation or structured row planting. It produces very large, shiny black, elongated, firm, juicy, and richly sweet fruits, perfect for fresh consumption, baking, and processing. Its summer fruiting, on previous year's canes, ensures an abundant mid-season harvest. Its dense green foliage attracts pollinators and contributes to the garden's nutritional appeal. Rubus fruticosus 'Columbia Giant' combines high yield, spectacular size, and easy cultivation thanks to its thornless nature.
