The calla lily, with its elegant trumpet-shaped blooms and lush foliage, is a favorite among gardeners. But does this beauty grace our gardens year after year, or is it a fleeting visitor? The question of whether calla lilies return annually is a common one, and the answer isn’t always straightforward.
The Calla Lily’s Comeback: A Matter of Climate and Cultivar
The truth is, whether a calla lily comes back each year depends heavily on your climate and the specific type of calla lily you’re growing.
The Role of Climate
Calla lilies, scientifically known as Zantedeschia, are native to South Africa, where they thrive in warm, sunny climates. In regions with mild winters, calla lilies can be grown as perennials, meaning they’ll come back year after year. However, in colder climates, they are treated as annuals, as they won’t survive the harsh winters.
The Difference Between Hardy and Tender Calla Lilies
Calla lilies are broadly classified into two categories: hardy and tender.
- Hardy Calla Lilies: These varieties, like the ‘Black Magic’ and ‘White Swan’ cultivars, are known for their cold hardiness and ability to withstand temperatures as low as -10°F. They can be grown as perennials in USDA hardiness zones 7-10.
- Tender Calla Lilies: These cultivars, such as the ‘Picasso’ and ‘Pink Mist’ varieties, are more sensitive to cold and can only withstand temperatures down to 40°F. They are best grown as annuals in colder climates or as container plants that can be brought indoors during winter.
Ensuring Your Calla Lily’s Return
If you live in a climate where calla lilies can be grown as perennials, there are several steps you can take to encourage their return:
- Choose the Right Location: Calla lilies thrive in partial shade and well-drained soil. Avoid planting them in areas prone to frost or heavy shade.
- Provide Adequate Water: Calla lilies need consistent moisture, especially during the growing season. Water deeply and regularly, but allow the soil to dry slightly between waterings.
- Fertilize Regularly: Feed your calla lilies with a balanced fertilizer every few weeks during the growing season to promote healthy growth and blooming.
- Mulch for Winter Protection: In colder climates, apply a layer of mulch around the base of your calla lilies to help protect the roots from freezing temperatures.
When Calla Lilies Don’t Return: Possible Reasons
Even if you’ve taken all the necessary steps, there are some reasons why your calla lilies might not return:
- Winter Kill: If the winter is particularly harsh, even hardy calla lilies can succumb to freezing temperatures.
- Disease or Pests: Calla lilies are susceptible to certain diseases and pests, which can weaken them and prevent them from returning.
- Poor Drainage: Soggy soil can lead to root rot, which can kill your calla lilies.
- Insufficient Sunlight: While calla lilies prefer partial shade, they need a minimum amount of sunlight to thrive. Too much shade can prevent them from flowering and returning the following year.
Bringing Back Your Calla Lilies: Propagation Methods
If your calla lilies haven‘t returned, don’t despair! You can easily propagate new plants from existing ones. Here are a few methods:
- Division: Divide the clumps of calla lilies in the spring or fall. Each division should have at least one growth point.
- Seeds: Collect the seeds from the spent flower stalks and sow them in a seed tray.
- Cuttings: Take stem cuttings from healthy plants and root them in water or a rooting medium.
The Calla Lily’s Enduring Charm: Beyond the Perennial Debate
Whether they return year after year or not, calla lilies remain a popular choice for gardeners. Their elegant blooms add a touch of sophistication to any garden, and their ease of care makes them a great option for beginner gardeners. Even if you live in a climate where calla lilies are treated as annuals, their beauty and versatility make them well worth growing.
