Echinacea purpurea ‘White Swan’ / White Coneflower

‘White Swan’ is a white flowering variety.

If you’ve only got room for one perennial plant, Echinacea purpurea is certainly a contender. Long lasting blooms (July through October) attract bees, butterflies, and other beneficial insects. These long-lived herbaceous perennials are easy to grow in full sun to part shade. They spread gently by clumping and seed if you leave seed heads in place over winter, but they can also be dead-headed to prolong the bloom season and are excellent for cut flowers.
