Growing Calla Lilies: Hardiness, Moisture Needs, and Winter Storage

Calla lilies (Zantedeschia) are hardy to Zone 7.

Care

• Moisture: Evenly moist, not soggy.
• Light: Partial shade to full sun.
• Colors: Wide range available.

Overwintering (Zones colder than 7)

• Store cool, dark, dry (basement, not freezing, not warm).
• Or grow in containers; move indoors when cold.

Callas are pricey—protect your investment!
