LANDSCAPING INFO

  • Outstanding powder blue foliage with wide leaf blades
  • Maintains its upright shape when planted in poor soil with no fertilizer—too much water and fertilizer may cause a lax appearance
  • Good specimen or accent and is also stunning in mass plantings or in decorative urns
  • Airy seed heads hover above the top of the plant from July through fall; plant remains interesting through the winter months in its dormant stage
  • Cut back in spring before new growth appears
