Planting Calla Lily Seeds Immediately After Harvest

Calla lily (Zantedeschia) seeds lose viability quickly—plant right after pod ripens.

Process

1. Remove seeds from mature pod.
2. Sow in trays, keep moist but drained.
3. Provide strong light (48-inch fluorescent 8 inches above).
4. Germinate quickly; prevent damping off with sphagnum moss.
5. After frost, harden off 10 days in shade.
6. Plant in garden like mature plants.

In frost-free areas, grow on outdoors in shade. Seeds form corms, not bulbs.
