Very tough plant that makes attractive 12"-18" mounds of flowers. It's great for dry areas. Looks best if cut back in late summer when flowering slows down. May send out more flowers in late summer. Even if it doesn't, the foliage looks better when all the dead flowers are cut off. The mounds expand each year. I divide them and give away baskets full of divisions as gifts. This can be can done in fall or early spring -- there's always a birthday or special occasion, and anyone, even people with no gardening skill, can grow this.
