The Pale Purple Coneflower (Echinacea pallida) is an aggressive but low maintenance perennial of the Echinacea family. It requires full sun (at least 6 hours) and moist but well-drained soil to produce soft pink to soft purple flowers from mid-summer to early fall. Clay soil is best but it can also be planted in loam or sand. This drought-tolerant plant may grow to approximately 3-5 feet tall and 2-3 feet wide. When planting, space it 2 feet apart and remove the spent flowers to extend the bloom season. This is a great nectar source for pollinators.
