Rubus 'Prime-Ark Freedom' PPAF (Blackberry)

Prime-Ark® Freedom, a new variety developed by the University of Arkansas System Division of Agriculture, is the world's first thornless primocane-fruiting blackberry. Freedom is the fourth in the division's Prime-Ark® line of primocane-fruiting blackberries, which flower and fruit on each season's new branches, called primocanes, said John R. Clark, Division of Agriculture fruit breeder. Most blackberries only bear fruit on second-season canes, known as floricanes. "This unique type of blackberry fruits on current-season canes and second-season canes, potentially providing for two cropping seasons," Clark said. "Prime-Ark® Freedom is an exciting development as it is the first thornless plant of this blackberry type released for commercial introduction in the world." USDA zones 5-9 in cold hardiness.
