Moonbeam Coriopsis

Its pale yellow flowers are borne in great abundance above delicate, needlelike foliage and seem to blend well with practically every color we've tried. Flowers heavily from June through August, with repeat bloom till frost. 'Moonbeam' is one of those rare plants that can't be used badly. It makes a superb front-of-the-border plant but can also provide summer color in the rock garden or light up a foundation planting that is in danger of provoking yawns among passers-by. Superb with the blue racemes of Adenophora. It's one of the great perennials.
