Overview
Echinacea purpurea 'White Swan' is an upright, clumping, herbaceous perennial reaching 24–36 inches (60–90 cm) tall with a spread of 18–24 inches (45–60 cm). This is the standard white-flowered selection of E. purpurea, producing single, daisy-like flower heads 3–4 inches (8–10 cm) across with white ray florets that droop slightly from a prominent, dark copper-orange to bronze central cone. The white rays may develop a slight greenish or pinkish tint as they age. Flowers are borne on sturdy, branching stems from July through September. The basal foliage is dark green, coarsely textured, with the characteristic rough, sandpapery surface. Growth rate is moderate. Seed-grown, so some variation in flower color purity and ray angle occurs—occasional plants may show pale pink rather than pure white. Hardy to zone 3.
Native Range
Echinacea purpurea is native to eastern and central North America, in prairies, open woodlands, thickets, and meadows. White-flowered forms occur naturally in wild populations.Suggested Uses
Planted in borders, moon gardens, cottage gardens, and meadow plantings at 18–24 inch (45–60 cm) spacing. The white flowers brighten shaded edges and evening gardens. Combines with pink echinaceas, grasses, and blue-flowered perennials. Functions in native plant gardens and pollinator plantings. The dark cones attract goldfinches in winter. Not suitable for full shade or waterlogged soils. Seed-grown variation may produce occasional off-white or pale pink individuals.How to Identify
