After the major bloom period, the plant will start to become a bit shabby. The old blossoms turn brown and the original foliage becomes less showy. At this point a decision has to be made on when to cut this plant back. The problem is there still will be a few blossoms and it is hard to sacrifice flowers. The sooner the plant is cut back the quicker it will regrow new crisp, clean foliage and produce a few smaller flowers in the fall.

The only problem this plant has is in hot humid weather it can melt out. I have found this to be a truly dependable, landscape perennial. I have a planting by my front walk that was planted in the late 1990's (2016) and they are still going strong.
