I have this plant in my shade garden. It blooms almost all spring, summer and fall if deadheaded and watered. The flowers are understated but beautiful. The foliage is very attractive as well. This is a very solid performer. Update: I've had this for four year now, and have added more to my collection because it's a real asset to the garden. It gets bigger and bushier every year, and blooms more, and requires very little attention. I divided one early this summer, and it doesn't appreciate that much, but the divisions did survive and are recovering nicely after protesting a bit.
