Planting & Care
  • An early fall planting is best to allow for the roots to establish, thus giving it a stronger start in spring
  • Does not propagate well from seed
  • Will gradually spread in optimal conditions by rhizomes if left undisturbed
  • Benefits from a layer of shredded leaves in fall
  • Foliage dies back by late summer, earlier with dry soils
  • Seeds are spread by ants
