Growing Calla Lilies from Seed Pods

Seed Viability Requirement

Calla lily (Zantedeschia) seeds must ripen fully in dry pods on the plant. Green-harvested pods yield non-viable seed.

If Pods Were Ripe

1. Store dry seeds in sealed jar/bag, cool & dark.
2. Sow in January–February, ½ inch deep.
3. Germinate at 70–75°F under lights (40W, 8" above).
4. Transplant seedlings after frost; harden off 10 days in shade.

Critical Considerations

• Hybrid callas won't come true from seed.
• Seedlings take 2–3 years to bloom.
• In cold zones, dig corms each fall before frost.

Better Propagation: Divide rhizomes in spring for faster, true-to-type plants.
