I have six butterfly bushes, all different colors. They are great performers, some bigger than others. I cut them back in march or april , depending on the snow up here and if I can get to them. They perform faithfully for me every year, in fact, I was thinking about ordering the new one with three colors on the same bush. they will take full sun or part shade, they even shade some of my am sun loving hostas. great bushes.
