Suggested planting locations and garden types
  • City and courtyard gardens
  • Gravel garden
  • Flower borders and beds
  • Underplanting of roses and shrubs
Pruning

Remove any dying foliage in autumn, and cut down old flower stems after flowering; to reduce wind rock of tall cutivars while the plants are establishing, trim leaf fans to one third of their height

Diseases

May be susceptible to aphid-borne viruses, bacterial soft rot and grey moulds; see Iris diseases
