Need more late summer perennials to extend your season? Purple coneflowers will continue to bloom until frost then go dormant for the winter. Showy 4" rosy purple daisies are lightly fragrant and make good cut flowers for bouquets. The clumps spread slowly and can be carefully divided after 3 or 4 years. There is also a beautiful white variety called White Swan. If faded flowers are left in place, the bristly seed heads provide food for finches in winter.
The herb echinacea is derived from varieties of this flower. E. angustifolia is used nowadays as a fortifier of the immune system, mainly to prevent flu and minor respiratory diseases by increasing the body’s production of interferon.
