How to Grow

Cultivation

Plant bulbs 10cm deep: in frost-prone areas, grow in a cool greenhouse or conservatory in full light in peat-free, loam-based potting compost such as John Innes No. 2, and water moderately as growth starts, water freely when in full growth (adding a balanced fertilizer every fortnight), and reduce watering as the leaves fade, then keep dry until fresh growth starts; in frost-free areas with dry summers, grow in full sun in well-drained soil in a rock garden or among low shrubs

Propagation

Propagate by seed, sown at 13-18°C, as soon as it is ripe, or by division, removing bulblets from dormant plants and repotting or replanting straightaway

Suggested planting locations and garden types

  • Patio and container plants

Pruning
