Found this forming in the shade house the other day (a euphemism for an old chicken coop with a jade vine growing over it for shade and some metal roofing in it for benches...) and today it reached its full glory!!!

Anyone know what it is? The bloom is about 6-8" in diameter.... this is where I stick plants to grow out before being planted...and it is a population of un named un tagged plants. Disorganized? me?

Anyone else bless every moment in our gardens????? Aren't they full of surprises???
