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.
  • Pink Calla Lily (Zantedeschia rehmannii): Soft pink calla lily with delicate, cup-shaped blooms.
  • Purple Calla Lily (Zantedeschia albomaculata): Deep purple calla lily with small, spotted 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.
