Purple Coneflower

Praised for their large, daisy-like flowers which appear from midsummer thru fall, after many other perennials have finished blooming, Coneflowers are a mainstay in today's garden. If deadheaded, the bloom cycle will be extended. However, some spent blooms should be left on the plants in fall because their seeds provide winter food for finches and other birds. The dried seed heads also provide architectural interest in the winter.
