Fun, weird, helpful, or little known fact
This famous plant, famous for its medicinal properties, is native to the Rocky Mountain West. Because it can be confused with poison hemlock, which is deadly, and because it depends on mycorrhizal fungi, and so can’t be transplanted successfully, and because it is not overly abundant in our area, it is best to leave it alone.
