Calla lilies, with their elegant trumpet-shaped flowers and striking foliage, are a popular choice for both indoor and outdoor gardens. But can you plant a calla lily outdoors? The answer, thankfully, is a resounding yes! While they are often grown as houseplants, these stunning blooms can thrive in the right outdoor conditions. This guide will delve into the specifics of growing calla lilies outdoors, covering everything from choosing the right location to caring for them throughout the year.
Understanding Calla Lily Varieties
Before we dive into the specifics of outdoor planting, it’s important to understand that there are two main types of calla lilies:
- True Calla Lilies (Zantedeschia aethiopica): These are the most common type, known for their large, white flowers and glossy green leaves. They are generally hardy in USDA zones 8-10, meaning they can tolerate mild winters.
- Arum Lilies (Zantedeschia hybrids): These are hybrids with a wider range of colors, including yellow, orange, pink, and purple. They are generally less hardy than true calla lilies and may require some winter protection in colder climates.
Choosing the Right Location
The success of your outdoor calla lily planting hinges on selecting the perfect spot. Here’s what to consider:
- Sunlight: Calla lilies prefer partial shade to full shade, especially in hot climates. They can tolerate some morning sun but should be protected from the harsh afternoon sun.
- Soil: Well-drained soil is crucial for calla lilies as they are susceptible to root rot. Amend heavy clay soil with compost or sand to improve drainage.
- Moisture: Calla lilies thrive in consistently moist soil but don’t like to sit in water. Choose a location that receives regular rainfall or ensure you can provide adequate watering.
- Protection: In colder climates, consider planting calla lilies in a protected location, such as near a wall or fence, to shield them from harsh winds and frost.
Planting Calla Lilies Outdoors
Once you’ve chosen the ideal spot, it’s time to plant your calla lilies:
- Planting Time: The best time to plant calla lilies outdoors is in the spring, after the last frost.
- Spacing: Space calla lily bulbs 12-18 inches apart to allow for adequate growth.
- Depth: Plant the bulbs 4-6 inches deep, with the pointed end facing upwards.
- Watering: Water thoroughly after planting and continue to keep the soil consistently moist, especially during the first few weeks.
Caring for Your Outdoor Calla Lilies
Once your calla lilies are established, they require minimal care. Here’s a breakdown of essential maintenance:
- Watering: Water regularly, especially during dry periods. Aim to keep the soil consistently moist but not waterlogged.
- Fertilizing: Feed your calla lilies with a balanced liquid fertilizer every few weeks during the growing season.
- Deadheading: Remove spent flowers to encourage further blooming.
- Mulching: Applying a layer of mulch around the plants can help retain moisture and suppress weeds.
Protecting Calla Lilies in Winter
While true calla lilies are hardy in warmer climates, they may need some winter protection in colder zones. Here are some tips:
- Mulching: A thick layer of mulch around the base of the plants can help insulate the bulbs and protect them from frost.
- Winter Protection: In areas with harsh winters, consider digging up the bulbs and storing them in a cool, dry place over winter. Replant them in the spring when the soil has warmed up.
Calla Lilies: More Than Just Beauty
Calla lilies are not only stunning visually but also offer several benefits:
- Attracting Pollinators: Their vibrant flowers attract bees, butterflies, and other pollinators, contributing to a healthy garden ecosystem.
- Air Purification: Like other plants, calla lilies help purify the air by absorbing pollutants.
- Cut Flowers: Their long-lasting blooms make them excellent choices for cut flower arrangements.
The End of the Journey: A Final Thought on Calla Lily Care
As your calla lilies grace your garden with their elegant presence, remember that their journey is a testament to the beauty and resilience of nature. By providing the right conditions, you can enjoy their vibrant blooms year after year.
