Simply beautiful & perfect in my pond! Prolific with large blooms, nice foliage. Several large blooms on each stalk at a time. These do very well in clay, in a shallow kitty box on the top ledge in my pond, & in part sun. One of the most beautiful flowers I have. Simply love it & can't wait to see it every year!
