The Saskatoon Berry
Saskatoons (Amelanchier Alnifolia) are purplish-blue berries grown on a shrub-type bush. They are native to the Canadian prairies and southern portions of the Yukon and Northwest Territories.
The berry’s name is derived from the Cree word Mis-sask-quah-toomina. A member of the original surveying party for the town site of Saskatoon, reported that the First Nations people used to gather quantities of the berries. They walked through camps calling, what sounded like to member of the scouting party, “saskatoons, saskatoons.” {my note: apparently the saskatoonians had purplish-blue berries in their ears)
The Native people and early pioneers used saskatoons as a common food. The fruit is still popular today and is used in baking, jams, jellies and wines.
Early settlers recognized the potential to diversify their diets with this delicious fibre-rich berry. It provided a relatively good source of calcium, potassium, copper and carotene and an excellent source of manganese, matgnesium and iron (see below). It was an important food source during the depression in the 1930’s.
