I have had great results with this plant, and with not a ton of special care! Never needs staking, takes the too-sunny spot I planted it in before I knew any better,and has nice fall color right when the flowers are blooming for a neat effect. I will be dividing it this spring,and setting some of the clump into a shadier spot, will see how it does there. Very nice cultivar, and very consistent performer!
