Sunflower.

At the side of our driveway, growing out of a crack  in the concrete, is this sunflower. When standing on tippy-toes, it just about manages a height of 2 feet, and is happily oblivious that a primary school Jnr managed to grow one in the garden that comfortably made six feet. The advantage of its diminutive size is that, when the gate is open, it can rest its chin on the cross piece.
