Patio

This is a butterfly bush. Somehow a seed got into the cracks of our patio and it just started growing. I don't have the heart to pick it yet but it will have to go since it is smack in the middle of the it. But I just thought it was so cool. I will probably transfer it to another part of the yard if the roots are ok.
This has happened several years ago but with a watermelon seed. It got into the crack of the patio and we let it grow all summer long. It took over the area and actually produced watermelon. I wonder what the patio has that the garden doesn't. Things seem to grow better in the patio.
