Sun flowers within sunflowers

 This is a small "Giant Sunflower" in my garden. It's only about 4 or 5 inches in diameter. It's trying really hard to make sunflower seeds. 

 

This is auch larger sunflower. It's head is easily over 1 foot in diameter. Each of the seeds in the head will be made with one of those teeny tiny flowers . 

Here is a zoomed in view of seed flowers.

I just think it's really cool.
