Description
Echinacea purpurea 'White Swan' is a compact perennial of upright growth, with large daisy-like flowers with slightly drooping white petals and large coppery-orange (often with a green tinge) central cones. The best flower display is from late June to late July, with sporadic continued bloom into September. Flowers grow on rigid, up to 3 feet (90 cm) tall stems. Leaves are dark green, lance-shaped, and coarsely toothed.
Hardiness
USDA hardiness zone 3a to 9b: from −40 °F (−40 °C) to 30 °F (−1.1 °C).
How to Grow and Care
Coneflowers are often listed as drought tolerant, but they will do much better with regular water. I leave the plants standing through winter to feed the birds. Shearing them back in the spring will result in bushier plants that bloom longer into the season. Deadheading is the primary maintenance required with Coneflowers. They are prolific bloomers, and keeping them deadheaded will keep them in bloom all summer. Luckily each flower remains in bloom for several weeks. Flowers start blooming from the top of the stem. As the initial flower fades, more side shoots and buds will form along the stem. Keep the plants deadheaded, and you'll keep getting more flowers.
If you don't want to start your own seeds, plenty of varieties are available for purchase as plants, especially through mail order. Plants can also be divided or grown from stem cuttings. Coneflower can be planted in either spring or fall. Be sure to allow for good air circulation to prevent fungal diseases.
