Although found in some collections in the United States, Glass has never attained commercial importance in this country, probably because its place is taken by the Quackenboss, which it very closely resembles. The fruit is large and attractive in color and shape, but it is not high in quality and it must be rated among Domestica plums as only a mediocre fruit. The tree is said generally to give better satisfaction than the fruit. This variety originated with Alexander Glass, Guelph, Ontario, and has been cultivated extensively by Canadian growers to whom its productivity and hardiness recommend it. Tree large, vigorous, upright-spreading, open, productive, hardy; branches rough, stocky; branchlets rather slender, pubescent; leaves folded backward, obovate or oval, one and three-quarters inches wide, three and one-half inches long; margin finely serrate; petiole reddish, pubescent, with from one to three smallish, globose glands usually at the base of the leaf. Fruit mid-season; one and one-half inches by one and three-eighths inches in size, oblong-oval, purplish-black, overspread with thick bloom; stem adhering firmly to the fruit; skin thin, tender, rather sour; flesh light yellow, juicy, firm, sweet, mild; of fair quality; stone clinging, one inch by five-eighths inch in size, irregular-oval, with oblique apex, the surfaces rough and pitted; ventral suture prominent, winged.
