I love seeing the layouts of your gardens. Looks to me like a lot of grass back there by the back fence though!!!
BTW, the spotting / blotching on the flower look like rain/moisture spots to me. If a daylily prone to this starts to open in the middle of the night when we have humidity here, I see that look. I had to get rid of a beautiful daylily that did this too often.
And now another beauty is threatening to do it as well. Still have that one though as it did itself right last year!
