Columbia is a prairie hardy crabapple, or applecrab, from Malus baccata and 'Broad Green'. It was bred in the Saunders program at Ottawa and was one of the original Saunders hybrids remembered in prairie fruit literature. Sources place its introduction in 1910 or 1911. [S6] [S9] [S8]
Prairie references link Columbia to the Experimental Farm at Ottawa and to William or W. M. Saunders. A later profile also credits its release to the Dominion Experimental Farm Service. One history of prairie apples identifies it as one of Saunders' first cross selections that stayed in commercial listings long afterward. [S9] [S6] [S1]
The fruit is small to small medium, about 3 to 4 cm across, conic to nearly round, and often ribbed. It is pale green or yellow with a strong red wash and darker striping. The flesh is yellowish and juicy, with a sub acid to acid, slightly astringent flavor. Sources agree it was not mainly a dessert apple. Quality is rated fair to good, but it is repeatedly described as too sour for eating raw. It ripens late, usually from late September into October, and one source gives it a storage life of about five weeks. [S4] [S6] [S10]
Columbia was valued more for use than for fresh eating. Prairie sources recommend it for jelly, juice, canning, sauce, and ornamental use. One recommendation list places it among the highly recommended crabapples for much of the prairie region. [S4] [S1] [S6]
The tree is described as a strong, vigorous grower that is tall, rounded, very productive, extra hardy, and comparatively free of fire blight. Sources also describe it as one of the best and hardiest of the original Saunders hybrids, with frost resistant fruit. Its seedlings were widely valued as vigorous, even, hardy rootstocks for prairie conditions, although Columbia itself was considered poor as a stembuilder because it tended to split. [S8] [S6] [S4] [S1]
Hardiness is one of the main reasons Columbia mattered historically. Sources place it in the hardest prairie class, describe it as dependably hardy, and one profile states it is hardy to Zone 1. Its long use and recommendation in prairie Canada, including Alberta and the Prairie Provinces, fits that picture. [S1] [S6]
In the broader archive, Columbia matters both as an early hardy baccata hybrid and as later breeding material. It appears as a parent in crosses such as Columbia x Dr. Bill and Columbia x Wealthy, and a University of Saskatchewan ancestry table still records a small contribution from Columbia in advanced selections. Those later breeding records show influence, not Columbia's own parentage. [S7] [S3] [S5]
