3rd Generation Sunflower

I planted a sunflower close to my front porch two years ago. Last year a few feet in front of the original location another grew without me planting it...seeds fell and it replanted itself. This year a few feet further the same thing happened. Nature takes care of itself if we let it. Beautiful. I keep thinking there should be a smiley face in the middle of it...it surely makes me smile (click it for a larger view).
