I've never grown this plant before and have been watching the purple lobes filling out, when suddenly a white head popped through, and then more arrived. So much fun watching these. It was a bit breezy when I took this, so it's not entirely sharp. I think the hummingbirds might like this because I got buzzed by one when I was taking this picture. http://www.missouribotanicalgarden.org/PlantFinder/PlantFinderDetails.aspx?kempercode=b954
