How to grow

Cultivation

Grow under glass or in containers that can be moved indoors over winter. Plant bulbs in autumn with the neck and shoulders above the soil surface, in a loam-based potting compost in full light. See hippeastrum cultivation for more detailed advice

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.
