Giant Sunflower peeping over fence

On our walk the other day, we were walking past our neighbor's house as usual and there was a giant sunflower peeping over the fence! It had not been there before and I had no idea our neighbor even had giant sunflowers planted in his backyard. What a nice surprise! I suppose I could have gotten closer to the fence for a better look, but when it is Brownie and I and I didn't know if he was home or not, I thought I'd better just take the picture from the sidewalk.
