Measuring up to 45cm in length and with an average weight of up to 11g per berry, Reuben produces fruit like no other blackberry! A fully mature plant can yield up to 7 x 500g punnets of fruit - that would cost about £56 in a supermarket ! Berries taste fabulous straight from the plant and boast an incredible level of sweetness. A sweet strawberry measures between 85 and 95 on the Brix scale - Reuben scores on average 115! The easiest blackberry for gardeners to grow and look after
