Columbia Sunrise is thornless trailing blackberry cultivar with excellent quality of fruit. Blackberry Columbia Sunrise is introduced as a very early ripening, thornless trailing blackberry with large, firm fruit, superb 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. As with its half-siblings, blackberry cultivar Columbia Sunrise has the Lincoln Logan source of thornlessness.
The harvest season is identical to Columbia Star cultivar. Fruits are large, weight is about 8 g. Shape is conic. Drupelets are fairly uniformly sized, shaped and arranged, drupelet fertility excellent. Fresh fruit flavor is very good, sweet. Aroma is good, sweet-acidic balanced, typical of western blackberries. Yield is about 5 kg per plant. Very early ripening, thornless trailing blackberry with large, firm fruit with a very good sweet flavor and good yields.
The primocanes of Columbia Sunrise were as vigorous as those of Marion and Black Diamond varieties but were less vigorous than those of Columbia Star or Chester Thornless. Columbia Sunrise fruits are well suited for processing or local fresh market sales. When eaten, Columbia Sunrise fruit texture was rated very good but poorer than Columbia Star and Marion varieties, and much more desirable than Chester Thornless cultivar.
Winter hardiness and disease resistant is good. Also Columbia Star has low tolerance to heat and ultraviolet damage.
