Apple

About Apple in Alberta

Apple (*Malus domestica*) is a small to medium deciduous fruit tree of Central Asian origin, introduced to Alberta entirely through human planting and not native to North America. In Alberta, apple trees are found almost exclusively in cultural landscapes -- home orchards, acreages, farmyards, community edible gardens, and old homestead sites -- rather than in any wild or naturalized setting. The province's cold climate requires Zone 2 and Zone 3 prairie-bred cultivars developed specifically for prairie survival, many originating from breeding programs at Morden, Manitoba and at Brooks, Alberta. For ARA purposes, apple's significance is nearly always cultural and historical rather than ecological: old farmstead survivor trees, long-established community orchard plantings, and documented specimens of heritage prairie cultivars represent the most noteworthy Alberta apple records.

Identification: Leaves are simple, alternate, and elliptic-ovate to ovate-lanceolate, typically 4-13 cm long and 3-7 cm wide. The base is usually rounded. Margins are irregularly serrated to finely toothed. The upper surface is dull green and generally hairless at maturity; the lower surface is pale gray-green with short fine gray hairs that persist even on mature leaves. The hairy undersides are one of the more consistent and field-useful close-inspection traits.

Alberta range and habitat: Apple has no wild distribution in Alberta. It is not naturalized in the province. Trees that appear in fence lines, field edges, or semi-disturbed ground are best interpreted as persistent former plantings, root sprouts from old orchard stock, or seedling descendants of cultivated material rather than genuinely naturalized populations. Naturalization of *M. domestica* is documented in British Columbia, Manitoba, Ontario, Quebec, and the Maritime provinces, but Alberta's colder and drier conditions have not supported the same pattern.
