How to Grow

Cultivation

Plant from October to January using peat-free John Innes No.2 into pots a little larger than the bulb itself. Two-thirds of the bulb should remain above the surface. Place in a well-lit spot at 21°C. Water sparingly until the new leaves develop and then start watering regularly. Turn the pot regularly to prevent the flower stem from bending toward the light. Once in flower, move the pot to a cool room to extend the flowering period. See hippeastrum cultivation and bulbs for Christmas flowering for further information

Propagation

Propagate by division, removing bulb offsets in autumn, or propagate by seed sown as fresh as possible, at 16-18°C (61-64°F). Keep young plants growing actively, in moderate warmth, allowing no periods of dormancy

Suggested planting locations and garden types

  • Houseplants
  • Conservatory and greenhouse
  • Cut flowers

Pruning

Cut back flowering stems as they go over. Cut back leaves as they go yellow, when bulb is going into dormancy

Pests

May be susceptible to bulb scale mite and narcissus bulb fly

Diseases

Generally disease-free
