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.
