As a size reference, I perched my (monster high) bee girl on the leaf stem. You can't see the bottom of her legs, so she is about 7" high in the photo. The smaller leaves are part of a morning glory plant that decided to climb up the trunk of the sunflower plant. At the bottom left of the photo is the actual sunflower on this particular plant. It was standing straight up, but after we had thunderstorms, it drooped and never recovered.
