Is a Calla Lily an Indoor or Outdoor Plant?

Published in Plant Cultivation 3 mins read

Calla lilies are remarkably versatile plants that can thrive as both indoor houseplants and outdoor garden specimens, depending on the climate and specific growing conditions.

Versatility of Calla Lilies Explained

The adaptability of calla lilies allows them to be enjoyed in various settings, making them a popular choice for both home decor and garden landscapes.

  • Indoor Houseplants: Callas can be successfully grown as vibrant houseplants throughout the entire year. When cultivated indoors, they provide consistent beauty and elegance to living spaces.
  • Outdoor Annuals: During the warmer summer months, calla lilies are often utilized as stunning annuals. They can be planted in outdoor pots, adding a splash of color to patios and balconies, or directly in the ground to enhance garden beds and borders.

Important Consideration for Outdoor Cultivation: For calla lilies grown outdoors, particularly in regions with colder winters, a key management practice is required. As the reference states, "Callas... will have to be dug and stored dormant inside to keep them another year." This means their bulbs (rhizomes) need to be lifted from the ground before frost, stored in a cool, dry, and dark place over winter, and then replanted the following spring.

Key Considerations for Growing Calla Lilies

Understanding the different ways calla lilies can be grown helps in choosing the best approach for your environment.

Feature Indoor Cultivation Outdoor Cultivation (as annuals)
Primary Use Year-round Houseplant Summer Annual (Pots or Ground)
Climate Dependence Minimized (controlled environment) Suited for Warm Season (dig & store for cold climates)
Dormancy Management Can be encouraged or not, depending on variety/care Required to overwinter bulbs in cold regions
Light Needs Bright, indirect light Full sun to partial shade (dependent on heat intensity)
Water Needs Consistent moisture; allow topsoil to dry slightly Consistent moisture, especially during blooming

This flexibility makes calla lilies a fantastic choice for gardeners and plant enthusiasts who appreciate their distinctive form and vibrant colors.

Benefits of Calla Lilies in Different Settings

Whether you choose to grow them indoors or outdoors, calla lilies offer distinct advantages:

  1. Indoor Elegance: As houseplants, they bring a sophisticated touch to interiors, perfect for living rooms, offices, or sunrooms, blooming in a controlled environment.
  2. Outdoor Impact: In gardens, they create dramatic focal points, add structural interest, and provide continuous blooms throughout the summer, making them ideal for garden beds, borders, and container arrangements.

In conclusion, a calla lily is truly a versatile plant capable of thriving in both indoor and outdoor environments, making it a valuable addition to diverse plant collections.
