‘Columbia Giant’ is a new thornless trailing blackberry (Rubus subg. Rubus Watson) cultivar with very large fruit from the U.S. Department of Agriculture-Agricultural Research Service (USDA-ARS) breeding program in Corvallis, OR, released in cooperation with Oregon State University’s Agricultural Experiment Station. ‘Columbia Giant’ is introduced as a high quality, high yielding, thornless trailing blackberry with good flavor and firm fruit that are suited for local fresh market sales but can be machine harvested for the processing market with very good frozen quality. ‘Columbia Giant’ should be adapted to areas where other trailing blackberries can be grown successfully. A U.S. Plant Patent has been granted (USPP18,369).
