How to Grow

Cultivation

Grow in moist, acid soil, planting bulbs to at least three times their own depth as they are stem rooting. Needs a sunny, sheltered position in a mild area. Otherwise grow in containers and take undercover in winter

Propagation

Propagate by seed, sown, when ripe, in containers in a cold frame or separate offsets after the foliage dies down

Suggested planting locations and garden types

  • Cottage and informal garden
  • Patio and container plants
  • Cut flowers
  • Flower borders and beds

Pruning

Deadhead after flowering and allow foliage to die down naturally

Pests

May be susceptible to lily beetle, aphids, slugs, snails, Thrips, leatherjackets, and wireworms, and to damage by rabbits and voles; plants in containers may be susceptible to vine weevil

Diseases

May be susceptible to grey moulds and a virus; see lily diseases
