I grew KEY TO MY HEART for many years. I loved this plant. It increased well in my Zone 5 garden. I decided to get rid of it, because the outer petals would frequently "canoe". I wanted the blooms to lay flat and they would not. I would manipulate the bloom to be wide open to only find the outer edges to curl up. I suspect that the petals were not as thick at the edges and thus they curled. I loved the color and the hardiness. I would still grow it not for the canoeing.
