Hartweg's Iris (Iris hartwegii)
Blooms: May - July
Hartweg's Iris and Western Blue Flag are nearly impossible to tell apart. It might help to remember that Western Blue Flag prefers wetter areas, grows taller (up to two feet high), and only comes in purple. Or it might not. The happiest approach, probably, is not to care - just call it an iris and consider the matter settled.
