How to grow

Cultivation

Plant bulbs in autumn, 10-15cm deep in fertile, humus-rich, moist but well-drained soil. Will grow in sun or partial shade, but does not tolerate waterlogging. Mulch in winter in cold areas. May have the potential to become a nuisance due to prolific self-seeding if not managed well

Propagation

Propagate by seed sown as soon as ripe, or by division, removing offsets from the parent bulb when dormant in summer
