Botanical nameSaskatoon berry

Amelanchier alnifolia 'Thiessen', or 'Thiessen' saskatoon berry, is a vigorous fruiting cultivar renowned for producing some of the largest fruits of the species, with sweet, juicy, and very sugary flesh. Its spring bloom of delicate white flower clusters attracts pollinators, while its deep green foliage creates a rich and dense mass effect, enhanced by warm colors in the fall. Ideal for edible hedges, natural orchards, or food crops, it offers excellent yield for fresh consumption, jams, juices, or drying. Robust and easy to maintain, 'Thiessen' combines beauty, abundant production, and reliable hardiness, while supporting local biodiversity.
