World's largest sunflower

Alise's kindergarten teacher gave her a sunflower seed to plant at the end of the school year.  Jenny thought it would be small, so she planted it in the middle of our shrub bed.  As you can see, it is anything but small.  This picture was taken a few weeks ago at the height of the sunflowers glory.  It has since bent almost in half due to the weight from the sunflower head.  This picture isn't an illusion, the plant really is as tall as our house.
