Thiessen Saskatoon is a long established Amelanchier alnifolia cultivar. It comes from a plant found by Maria Loewen Thiessen at Hepburn, Saskatchewan, in 1906, and was introduced in 1976. It was selected for large sweet berries that can reach about two thirds of an inch across, among the largest Saskatoon fruit.
Thiessen grows as a taller open shrub or small tree with berries ripening over several weeks. Seedlings are not clones and will vary, although many may retain useful traits in berry size or flavour.
