Thiessen Saskatoon Seeds

Thiessen Saskatoon is a long established Amelanchier alnifolia cultivar introduced in 1933 by Niels Hansen at the Dominion Experimental Farm in Saskatchewan. It was selected for large sweet berries that can reach 17 mm 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.
