Buffalo Beans or Thermopsis rhombifolia is a plant that blooms early in the spring. If you’ve spent time outdoors in the Saskatchewan prairies, you’ve likely seen them growing in ditches and pastures. They are also known as “Golden Beans” or “Prairie Bean”.
Although they are members of the pea family and produce bean like pods, they are also toxic and so should not be eaten.
First Nations people used the Buffalo Beans as a source of yellow dye and to time their bison hunt. It is said that when the Buffalo Beans bloomed, the bison would be passing through and their meat would have of the desired quality for hunting.
