Overview
Oregon is the predominant source of cultivated blackberry production. According to the USDA, Oregon raised 41 million pounds of blackberries in 2006. The value of fresh and processed blackberries in 2006 was $35 million.
Blackberries are classified based on growth habit. There are erect varieties, semi-erect and trailing. The erect varieties do not need trellised if they are properly pruned. Semi-erect and trailing blackberries require trellising. A bramble is a term used to describe blackberries and raspberries. Both species derive from the genus Rubus.
