Growing Tips
Bulbils germinate more readily than true seeds. Keep substrate moist but not waterlogged. Remove wing-like structures from seeds if present. Plant in autumn for best results. Do not cover container initially; uncover once most germinate. Maintain temperature around 20°C (68°F). Good drainage essential to prevent rot.
