Are Calla Lilies Indoor or Outdoor Plants?
Calla lilies, with their sleek trumpet-shaped flowers and lush green foliage, are a favorite among gardeners and flower enthusiasts alike. But if you’re thinking about adding them to your home or garden, you may be wondering: Are calla lilies indoor or outdoor plants? The answer isn’t quite black and white—these stunning plants can thrive both indoors and outdoors, depending on how you care for them.
In this article, we’ll explore the versatility of calla lilies, the best growing conditions for each environment, and tips for keeping them blooming beautifully year-round.
What Are Calla Lilies?
Calla lilies (Zantedeschia spp.) are not true lilies but are part of the Araceae family, native to southern Africa. Known for their elegant blooms and vibrant colors—from classic white to pink, purple, orange, and even black—calla lilies symbolize beauty, purity, and rebirth.
They can be grown as perennials in warm climates or as annuals in colder zones, making them a flexible option for many gardeners.
Can Calla Lilies Be Grown Indoors?
Yes—With the Right Care
Calla lilies make excellent indoor plants when provided with the proper care. They’re especially popular as houseplants or decorative potted flowers for special occasions like weddings or Easter.
Key indoor growing tips:
- Light: Bright, indirect sunlight is ideal. A south- or west-facing window is best.
- Temperature: Keep them in a consistent environment between 60–75°F (15–24°C).
- Humidity: Moderate to high humidity mimics their native tropical habitat.
- Watering: Keep soil moist but not soggy. Overwatering can lead to root rot.
- Container and Soil: Use a well-draining potting mix and a pot with drainage holes.
💡 Pro tip: Let the plant go dormant after blooming by gradually reducing watering. Resume care after a couple of months to encourage reblooming.
Can Calla Lilies Be Grown Outdoors?
Absolutely—In the Right Climate
Calla lilies thrive outdoors in USDA hardiness zones 8–10, where winters are mild. In cooler regions, they can be grown during the warmer months and then brought indoors before the first frost.
Outdoor care essentials:
- Sunlight: Full sun to partial shade. In hot climates, partial shade prevents scorching.
- Soil: Rich, well-drained soil with plenty of organic matter.
- Spacing: Plant bulbs 4–6 inches deep and 12 inches apart for good air circulation.
- Watering: Water regularly, especially during dry spells.
🌱 In colder zones: Dig up rhizomes in fall, dry them, and store them in a cool, dark place until spring.
Pros and Cons of Growing Calla Lilies Indoors vs. Outdoors
| Feature | Indoors | Outdoors |
|---|---|---|
| Bloom Duration | Shorter but manageable with care | Often longer and more natural |
| Maintenance | Requires more control over light/water | More weather-dependent |
| Pest Control | Easier to manage | Susceptible to snails, slugs, aphids |
| Mobility | Can move to ideal conditions | Needs protection in harsh weather |
| Aesthetic Appeal | Great for interior decor | Perfect for garden beds and borders |
How to Transition Calla Lilies Between Indoors and Outdoors
If you’d like the best of both worlds, it’s possible to move your calla lilies indoors for winter and back outside in spring.
Steps for a smooth transition:
- Before frost hits, carefully dig up outdoor calla lilies.
- Let the bulbs dry for a few days, then store in a cool, dry place (like a garage or basement).
- In spring, plant them back outdoors after the last frost, or pot them indoors to restart growth.
This cycle helps you extend the life of your calla lilies while enjoying them all year long.
Common Issues and Troubleshooting
Calla lilies are generally hardy, but you might encounter a few challenges:
- Yellowing leaves: Usually a sign of overwatering or poor drainage.
- No blooms: Could be due to lack of sunlight or nutrients.
- Mold or mildew: Improve air circulation and avoid overhead watering.
- Pests: Indoors, watch for spider mites. Outdoors, look out for slugs and aphids.
Regular inspection and maintenance go a long way toward keeping your plants healthy.
Conclusion: So, Are Calla Lilies Indoor or Outdoor Plants?
Calla lilies can be both indoor and outdoor plants, depending on your location and care routine. Indoors, they offer elegance and year-round greenery. Outdoors, they add bold color to gardens and landscapes—especially in warmer climates.
Whether you’re decorating your living room or brightening up your flower beds, calla lilies are a versatile and rewarding choice for any plant lover.
