van Zyl opal flower

Plant bulbs 10cm deep: in frost-prone areas, grow in a cool greenhouse or conservatory in full light in loam-based potting compost such as John Innes No. 2. 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

No pruning required

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
