I fell in love with Prairie Princess at the Royal Botanical Garden in Ontario, where they had a row of them, all about seven feet high and quite full. I have grown several in CT for ten years now and continue to value it among my favorites. My bushes tend to get leggy, even with considerable pruning, and so the blooms after the first flowering are all at the tops of the plants. They are my best repeat bloomers, though, and their beauty generates comment even in July and August.
