Oxford is listed as a nigra plum and described as an early variety from Minnesota. At the South Dakota Station, it had not fruited enough to judge its full value, so the surviving record depends mainly on remarks from regional observers rather than a full Station evaluation. J. S. Harris, quoted from Wisconsin Bulletin 63, called it the earliest variety fruited there. [S1]
The fruit appears to have been large and early. Harris said the fruit quality closely resembled Aitkin, and the tree was also said to resemble Aitkin in foliage, wood color, and growth habit. A. Norby added that the fruit was large and ripened early, though the printed sentence breaks off before the last point is completed. [S1]
Oxford is lightly documented but still suggestive as a northern plum: a Minnesota selection, classed with nigra plums, remembered for earliness, and compared closely with Aitkin in both tree character and fruit quality. The surviving South Dakota note does not establish productivity, storage, disease behavior, or broad hardiness in detail beyond its inclusion in this regional trial literature. [S1]
