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.
Cold Hardiness Zone: 2
Stratification Required: 3 to 4 months cold
Mature Size: 12 to 14 ft

More about this plant
Saskatoon is native to Manitoba and western and northwestern North America. Species guidance favours full sun and well-drained loam or sandy loam with adequate moisture, while avoiding chronically wet roots. Plants can sucker into thickets, although the amount varies. The species is self-fruitful, and bee-mediated cross-pollination can improve fruit set. Thiessen is described as early, large-fruited, low-suckering and excellent-flavoured, but seedlings from this lot remain genetically variable.
