Blue Flax is a delicate native wildflower of western prairies and mountain meadows, producing sky-blue flowers that last only one day before dropping. New blooms open every morning throughout the summer, giving a continuous display. It is closely related to cultivated flax and was used by indigenous peoples for strong fibers. Small native bees and beetles are its pollinators.
