  • Recipient of the prestigious Award of Garden Merit of the Royal Horticultural Society for its outstanding qualities
  • Performs best in full sun or part shade, in average, medium moisture, well-drained soils. Prefers moist and humus-rich soils.
  • A perfect border plant which looks quite attractive when massed.
  • May need some support if the soil is too rich.
  • Propagation via division or seed. Division may be done in the spring (preferable) or fall. Seed is best sown outside in the fall and will germinate the following spring.
