From a distance the flower could be mistaken for Iris virginica for it's size and color, except that the gentians bloom in late summer/early fall.  Well, it is a little smaller than an iris but the color is dead on. Some authors place the fringed gentians in the genus Gentianopsis and would call this species Gentianopsis procera (Holm.) Ma. or Gentianopsis virgata (Raf.) Holub.
