How to grow

Cultivation

Grow in fertile, well drained soil, in areas that will not dry out in summer. Prefers full sun, flowering is likely to be reduced in shadier situations. Water freely from spring to summer. Divide every 2-3 years to maintain vigour. See hemerocallis cultivation for more advice

Propagation

Propagate by division in early spring, or in autumn at least six weeks before the first frost. Propagate from seed sown in containers in a cold frame in autumn or spring

Suggested planting locations and garden types
  • City and courtyard gardens
  • Cottage and informal garden
  • Patio and container plants
  • Flower borders and beds
Pruning

Cut back flower stems after flowering has finished. Remove dead foliage as required

Pests

May be susceptible to hemerocallis gall midge, aphids, glasshouse red spider mite and thrips. Slugs and snails may damage young leaves

Diseases

May be susceptible to rust. In climates with alternating winter frosts and thaws, bacterial leaf and stem rot (spring sickness) may be a problem; in areas with high temperatures and high humidity, crown rot may cause damage
