Understanding Calla Lilies and Their Needs
Calla lilies, scientifically known as Zantedeschia, are not true lilies but belong to the Araceae family. They are native to South Africa and thrive in warm, humid environments. However, they have adapted well to various climates, including the temperate regions of Illinois.
Here’s a closer look at their needs:
- Sunlight: Calla lilies prefer partial shade to full shade, especially during the hottest months of summer. Direct sunlight can scorch their leaves, leading to wilting and discoloration.
- Soil: Well-drained soil rich in organic matter is ideal for calla lilies. They prefer a slightly acidic pH range between 6.0 and 7.0.
- Water: Calla lilies require consistently moist soil, especially during their active growth phase. However, they are susceptible to root rot if the soil is waterlogged.
- Temperature: While they can tolerate some cold, calla lilies thrive in temperatures between 65°F and 80°F. They are not frost-tolerant and will need protection during the winter months.
Choosing the Right Calla Lily Variety for Illinois
Not all calla lily varieties are created equal. Some are better suited for cooler climates than others. Here are a few popular options that thrive in Illinois:
- Calla Lily ‘Black Star’: This variety boasts striking dark purple flowers with a velvety sheen. It’s known for its cold hardiness and ability to withstand chilly temperatures.
- Calla Lily ‘Pink Mist’: This variety showcases delicate pink flowers with a subtle fragrance. It’s a reliable performer in Illinois, producing stunning blooms throughout the summer.
- Calla Lily ‘White Giant’: This variety is a classic choice, featuring large, pure white flowers with a graceful presence. It’s known for its vigorous growth and prolific blooming.
Planting Calla Lilies in Illinois
The best time to plant calla lilies in Illinois is in the spring, after the last frost has passed. Here’s a step-by-step guide:
1. Prepare the soil: Choose a location that receives partial shade to full shade. Amend the soil with compost or peat moss to improve its drainage and fertility.
2. Plant the tubers: Dig a hole about 6 inches deep and 12 inches wide. Place the calla lily tuber with the pointed end facing upward and cover it with soil.
3. Water thoroughly: After planting, water the soil deeply to encourage root development.
4. Mulch: Apply a layer of organic mulch, such as shredded bark or wood chips, around the base of the plants to retain moisture and suppress weeds.
Caring for Calla Lilies in Illinois
Once planted, calla lilies require consistent care to thrive. Here are some essential tips:

- Fertilizing: Feed your calla lilies with a balanced fertilizer every 4-6 weeks during their active growth phase.
- Deadheading: Remove spent flowers to encourage further blooming.
- Winter Protection: In the fall, before the first frost, cut back the foliage and dig up the tubers. Store them in a cool, dry place until spring.
Protecting Calla Lilies from Pests and Diseases
Calla lilies are generally resistant to pests and diseases. However, they can be susceptible to certain issues:
- Aphids: These small insects can feed on the leaves and stems, causing damage and stunted growth. Use insecticidal soap or a strong blast of water to control aphids.
- Slugs and snails: These pests can damage the leaves and flowers. Use a slug bait or hand-pick them from the plants.
- Root rot: This fungal disease can occur if the soil is too wet. Improve drainage and avoid overwatering to prevent root rot.
