Thornless Primocane- Fruiting Blackberry

prime-ark-blackberryPrime-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. Information about all fruit varieties is available from the University of Arkansas System Division of Agriculture and can be found at
