It rained here two days in a row, which was great because we really needed it. In between showers, I swished across the wet grass in the back yard because I saw something white. It turned out to be a few of these irises/lilies. I have found so many different names for this flower, from wild iris to butterfly lily. I am going to call it a wild iris because it just popped up. I know I didn't plant it!
