Calla lilies, with their trumpet-shaped blooms and glossy foliage, are an epitome of elegance and grace. These perennials, native to South Africa, are a popular choice for gardens and floral arrangements worldwide. If you’re considering adding these stunning plants to your landscape, here’s an in-depth guide on calla lily care and cultivation.
Growing Calla Lilies
Soil and Planting
- Calla lilies thrive in well-drained, humus-rich soil with a pH of 6.5-7.0.
- Plant rhizomes horizontally about 2-3 inches deep and 6-12 inches apart.
- Water thoroughly after planting and keep the soil moist but not waterlogged.
Light and Temperature
- Calla lilies prefer partial shade to full sun, but can tolerate some morning sun.
- They are not cold-hardy and can only withstand temperatures above 40°F (4°C).
- In colder climates, plant in containers that can be brought indoors during winter.
Watering and Fertilizing
- Water regularly, especially during the growing season, allowing the soil to dry slightly between waterings.
- Fertilize monthly with a balanced liquid fertilizer during the growing season.
Dormancy
- In the fall, the foliage of calla lilies will yellow and die back.
- After the foliage has died back, reduce watering and stop fertilizing.
- Dig up the rhizomes and store them in a cool, dry place over winter or leave them dormant in the ground in mild climates.
Types of Calla Lilies
Calla lilies come in a wide range of colors, including white, yellow, pink, purple, and even bi-colors. Some popular varieties include:
- White Calla Lily (Zantedeschia aethiopica): Classic white calla lily with large, trumpet-shaped blooms.
- Yellow Calla Lily (Zantedeschia elliotiana): Vibrant yellow calla lily with large, funnel-shaped blooms.

- Bi-Color Calla Lily (Zantedeschia hybrida): Stunning calla lily with blooms that feature two contrasting colors.
Calla Lily Care Tips
- Avoid overwatering, as this can lead to root rot.
- Deadhead spent blooms to encourage more flowering.
- Divide crowded rhizomes every 3-4 years to prevent overcrowding.
- Protect from slugs and snails, which can damage the foliage.
- Calla lilies are toxic to pets, so keep them out of reach.
