Ta dah!

That's what this buddleja seems to be saying about the sunflower.

The birds set this one for me. I've never had luck with sunflowers, the slugs always eat them, so I'm chuffed the birds have managed to succeed where I failed. They've planted quite a few seeds for me - Sav pointed out that we seem to have a cannabis plant too! I'm not sure, so we' going to let it grow to see what it is.
