The squirrels planted some black oil sunflower seeds from the feeder this winter on the bank at the back of my yard where my wife has her flower garden. She pulled them all out but two that I convinced her to leave. I have one that has a flower that measurers 13 inches across and that is with the petals wilted as it is now going to seed. I didn't think the black oil sunflowers got flowers that large.
When you are up to your butt in alligators, it is hard to remember your intent was to drain the swamp. Stay focused!
