Each year this flower grows in July right through a blacktop driveway. You can see in the photo that the blacktop has been pushed up by the growth. It starts with one long plant, then 7 or 8 baby shoots follow. They grow over 2 feet tall. I am just amazed at how this flower breaks through and comes back every year. Can anyone identify it?
