Wood lilies are normally shades of orange. The coral tones are particularly appealing. But they can range from a deeper red orange to yellow. Wood lilies are the floral emblem of Saskatchewan, and appear on their flag. There they call them western red lilies. The root was used by Indians for food and medicine. Kind of cool to have it both ways! I wonder if it worked?
In Rocky Mountain Flora, William Weber notes that, "This is a truly endangered species and should never be collected. It has never been common and evidently is fast disappearing where unprotected." It's my perception that wood lilies are less common here in Michigan than when I first started noticing them. Or maybe we just don't share as much of the same range as we used to.
