‘Columbia Sunrise’ is a new, very early ripening, thornless trailing blackberry (Rubus subg. Rubus Watson) cultivar 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 Sunrise’ is introduced as a very early ripening, thornless trailing blackberry with large, firm fruit with a very good flavor and good yields that will be suited for hand-harvested fresh and machine-harvested processed markets. ‘Columbia Sunrise’ should be adapted to areas where other trailing blackberries can be grown successfully. A U.S. Plant Patent has been applied for (USPPAF 15/330,508).
