White Swan' is the perfect name for this graceful echinacea, a natural selection from white-flowered variations of the native, purple echinacea. Its flowers attract butterflies and other pollinators, while birds enjoy the seeds. The cone-like seed heads also add a nice architectural touch to the winter garden. A long-lasting cut flower, it adds a sparkle of white to floral arrangements.
