Acheson is a standard apple cultivar. It is described as a seedling of 'Delicious' introduced at Edmonton, Alberta, in 1941. Sources credit J. H. Acheson. One earlier prairie bulletin names Mrs. J. H. Acheson. The selection is also linked to the University of Alberta context. [S1] [S2] [S3]
The fruit was remembered as a prairie apple of useful size and decent quality, not as a novelty. Descriptive sources call it large, greenish to greenish yellow, and ovate, with fine textured flesh and a sub acid flavor. One source rates its quality above medium. [S1] [S3] A later prairie index lists it as small to medium and mainly for processing. That may reflect a stricter table scale or different judgment of the fruit. [S2]
Season notes place Acheson from mid August into September. One source narrows this to late August. [S1] [S3] Use notes are limited, but the processing designation and the sub acid, fine textured flesh suggest it was valued at least as much for kitchen use as for dessert use. [S2] [S3]
Tree notes are brief but important. The 1946 prairie orchard bulletin says the tree was hardy and productive at Edmonton. This is the clearest direct hardiness evidence in the current source set. [S3] That places Acheson in an Alberta prairie context where winter survival and reliable cropping were central to a cultivar's value. [S2] [S3]
In lineage terms, Acheson belongs to the prairie history of locally selected apple seedlings derived from established cultivars and tested for actual orchard performance on the Canadian prairies. Its known parentage stops at 'Delicious' seedling in the present sources. No fuller cross or descendant breeding role is given here. [S1] [S2] [S3]
Acheson is notable less for a dramatic breeding story than for what it represents: an Edmonton seedling considered hardy, productive, and worth naming in prairie references across decades. [S1] [S2] [S3]
