One thing I notice when I do the garden tours is the lack of use of white irises in the beds. Either scattered with other plantings or just as a foil for the bolder and brighter irises. White is not my favorite color in irises but I have a few in different sizes and I have noticed they give different depth to a flower bed when viewed from a distance and really make the colored ones pop. Especially if you pair a white iris with a contrasting beard that matches the color scheme of that bed.
