Thunderhead Blackberry

Rubus watson 'Thunderhead', USPP34,914

'Thunderhead' is a novel blackberry cultivar that resulted from a carefully controlled crossing of the thorny primocane-fruiting blackberry plant ORUS 4355-2 and the thornless primocane-fruiting plant ‘Prime-Ark® Freedom’. Developed by the USDA-ARS breeding program in Oregon, it is the first of its kind and boasts strong plant vigor and high yields of medium-sized, glossy, and firm berries that are bursting with exceptional flavor and quality. Its small seed size adds to its appeal, making it an ideal choice for fresh consumption. With its genetic background originating from Eastern U.S. germplasm, this distinct variety is anticipated to thrive in most regions where primocane-fruiting blackberries are currently cultivated. This is not a thornless variety.
