Literally the only coneflower (other than the wild purple ones) that I can get to grow here.... seems like not many are hardy in our zones. Got this one in morning sun up till about 1:00pm, then the building blocks the sun completely. Not sure if this is helpful but this is where it seems to grow. Also maybe beacause it is blcok from the north winter winds?!?! Maybe that helps as well -- who knows!
