These plants are the first indication that fall is coming! I knew the natives used the berries for dye, but never knew they were edible. Think I will pass on the taste test!

Strawberry Blite: Red berry flowers
(Raspberries, I'd say, but the experts — includingVance/Jowsey, source of that info above — see them instead as strawberries.)
These plants are members of the very large Goosefoot family. (The weed — or pseudocereal — Lambsquarters is related, though far from as brightly coloured.)
The berry-like clusters of Strawberry Blite flowers are, in fact, edible, though very bland, according to the webpage for the Royal Saskatchewan Museum's Native Plant Garden.
