Growing Calla Lilies Outdoors

For gardeners who prefer the charm of open-air landscapes, growing calla lilies outdoors can be a delightful endeavor:

  • Outdoor Elegance: Calla lilies can thrive outdoors when provided with the right conditions. Their graceful blooms add elegance and a touch of sophistication to gardens, borders, and outdoor planters.
  • Optimal Outdoor Conditions: To successfully cultivate calla lilies outdoors, they require ample sunlight, well-drained soil with organic matter, and regular watering. They appreciate a location with morning sun and afternoon shade in regions with hot summers.
  • Watering and Soil: Keep the soil consistently moist but not waterlogged, as calla lilies prefer slightly damp conditions. Mulching around the base of the plants can help retain moisture and regulate soil temperature.
  • Climate Considerations: Calla lilies are sensitive to cold temperatures, so they are best suited for outdoor cultivation in regions with mild winters. Gardeners in colder climates may need to dig up and store the rhizomes during the winter months to protect them from frost.

Overwintering Calla Lilies

For those faced with frosty winters, overwintering calla lilies is essential to preserve their health and vitality:

  • Winter Protection: In colder climates, calla lilies are vulnerable to frost damage. To safeguard them during the winter, carefully lift the rhizomes (bulb-like structures) from the ground after the first frost but before the ground freezes.
  • Storage: Store the lifted rhizomes in a cool, dry place, such as a basement or garage, where temperatures remain above freezing but below 50°F (10°C). This prevents them from going dormant and allows you to replant them in the spring.
  • Spring Replanting: In the spring, as the danger of frost subsides and the weather warms, replant the calla lily rhizomes in the garden or containers. Resume regular outdoor care practices to encourage growth and flowering.

The beauty of calla lilies lies in their versatility, allowing gardeners to enjoy their charm in various settings:

  • Both Indoors and Outdoors: Calla lilies are unique in their ability to flourish indoors as elegant houseplants or outdoors as garden gems. Gardeners can choose the growing environment that best suits their preferences and local climate.
  • Container Gardening: Calla lilies excel in container gardening, making them adaptable to patio spaces, balconies, and even small gardens. Their portability and aesthetic appeal enhance any outdoor or indoor setting.
  • Landscape and Floral Arrangements: Calla lilies are not limited to garden beds; their cut flowers are a favorite choice for floral arrangements, weddings, and special occasions, showcasing their enduring popularity.


In conclusion, the choice of whether to grow calla lilies indoors or outdoors ultimately depends on your location, preferences, and the specific conditions you can provide. These versatile plants, celebrated for their graceful blooms and striking foliage, have the ability to thrive in both environments when given the appropriate care.

Indoor cultivation allows for year-round enjoyment and control over growing conditions, making calla lilies an appealing choice for houseplant enthusiasts. On the other hand, outdoor growing offers the opportunity to adorn gardens and landscapes with their elegance, provided the right outdoor conditions and winter protection are in place.

Regardless of your choice, the captivating allure of calla lilies and their adaptability make them a delightful addition to any gardening or floral arrangement venture. Whether they grace your indoor living spaces or flourish in your garden’s outdoor haven, calla lilies never fail to enchant with their timeless beauty.
