Windflower (Anemonastrum canadense),

Canada Anemone ranges naturally from the central southeastern states west to Nebraska and northward into Canada where it prefers low open fertile woods and damp meadows. It has basal, bright green, deeply cut leaves which resemble those of hardy Geranium, and flowers on slender 1 to 2 foot tall stalks in early summer. The 1 inch, daisy-like flowers are held singly and delicately. This Anemone can grow rampantly in part shade in moist, good soil and could be used to cover large areas. In part shade, growth will be slower.
