Ruffled and pure white these double flowers dance around a green center with yellow anthers. A great perennial to add to the mixed border since 'Whirlwind' start blooming when many perennials are slowing down. Known for its early fall blooms this cheery perennial really blooms on well branched vigorously branched form. Dark green foliage makes a dramatic backdrop to really showcase the flowers as they dance in the breeze.
Clump-forming plant with erect flower stems in fall. Summer drought and windy sites are not favored. Prefers moist, well-drained soil in sun to part shade. Cut back to the ground in late fall.
