This was one of the few late summer bloomers that I have spotted around here. It really likes to be on the roadside, which is slightly shaded next to a lot of woodland. Many garden centers actually sell this because of its numerous, lovely blooms that last into the fall.
Aaaaaand this is another flower that really burned out in the photo.
