The calla lily, with its elegant trumpet-shaped blooms and captivating beauty, has long been a favorite among gardeners. But the question of whether it thrives outdoors or indoors often arises. Is calla lily an outdoor plant? The answer, as with many things in gardening, is not a simple yes or no.
Calla Lily: A Versatile Beauty
Calla lilies belong to the genus Zantedeschia and are native to South Africa. They are known for their striking, waxy flowers that come in a variety of colors, from classic white to vibrant shades of yellow, pink, orange, and even purple.
While they are often seen as indoor plants, calla lilies can indeed thrive outdoors in certain climates. Understanding their specific needs and the conditions of your region is crucial for determining whether they will flourish in your outdoor garden.
The Key to Outdoor Success: Climate and Location
Calla lilies are generally considered hardy in USDA hardiness zones 8-10, meaning they can tolerate mild winters and grow outdoors year-round in these regions. However, even within these zones, their success depends heavily on the specific microclimate and location. Here’s a breakdown of what to consider:
- Sunlight: Calla lilies prefer partial shade to full shade, especially in warmer climates. Too much direct sun can scorch their leaves and diminish their bloom production.
- Temperature: These plants are sensitive to frost and cold temperatures. They require a minimum temperature of around 50°F (10°C) to thrive.
- Humidity: Calla lilies enjoy moderate humidity levels. If your area has low humidity, you might need to provide extra moisture, either through misting or placing the plants near a humidifier.
- Soil: Well-drained soil that is rich in organic matter is ideal for calla lilies. They prefer slightly acidic to neutral pH levels.
Growing Calla Lilies Outdoors: A Step-by-Step Guide
If you live in a suitable climate and have a shady spot in your garden, here’s a guide to growing calla lilies outdoors:
1. Choose the Right Time: Spring is the best time to plant calla lilies outdoors after the last frost has passed.
2. Prepare the Soil: Amend your soil with compost or well-rotted manure to improve drainage and fertility.
3. Plant the Bulbs: Space the bulbs about 12 inches apart in a well-prepared bed. Plant them with the pointed end facing upwards and cover with about 2-3 inches of soil.
4. Water Regularly: Keep the soil consistently moist but not waterlogged.
5. Fertilize: Feed your calla lilies every 2-3 weeks with a balanced liquid fertilizer during the growing season.
6. Protect from Frost: If you live in a borderline climate, cover your plants with a layer of mulch during the winter months to protect them from frost.
Calla Lilies and Their Unique Needs
While the above steps provide a general guide, there are some unique aspects to consider when growing calla lilies outdoors:
- Dormancy: Calla lilies enter a period of dormancy during the winter months. This is a natural process, and it’s essential for their survival. During dormancy, the foliage dies back, and the plant focuses its energy on developing new bulbs.
- Division: Once your calla lilies have established themselves, you can divide the bulbs every 2-3 years to encourage further growth and propagation.
Calla Lily: A Striking Addition to Your Outdoor Space
Calla lilies, when grown in the right conditions, can add a touch of elegance and sophistication to your outdoor space. Their vibrant blooms and lush foliage create a stunning visual contrast, making them perfect for borders, containers, or even as focal points in your garden design.
Calla Lily: A Plant for Every Season
While they are primarily known for their vibrant blooms during spring and summer, calla lilies can also be enjoyed indoors as potted plants. This versatility allows you to bring their beauty into your home during the colder months, ensuring you have a touch of their elegance year-round.
Beyond the Garden: Calla Lilies in Floristry
Calla lilies are not only popular in gardens but also widely used in floristry. Their distinctive shape and long vase life make them a favorite choice for bouquets, arrangements, and special events.
Final Thoughts: Embrace the Calla Lily’s Beauty
Whether you choose to grow them outdoors in your garden or indoors as potted plants, calla lilies offer a captivating blend of beauty, elegance, and versatility. By understanding their specific needs and providing them with the right conditions, you can enjoy their stunning blooms and lush foliage for years to come.
