Are Lilies Indoor or Outdoor Plants? A Complete Guide for Gardeners
Lilies are some of the most breathtaking and fragrant flowers you can grow. With their elegant blooms and rich symbolism, they’ve found a place in gardens, homes, and floral arrangements across the world. But if you’re thinking about growing lilies yourself, one question naturally arises: are lilies indoor or outdoor plants?
The answer isn’t quite black and white. While many lilies thrive outdoors, some can also adapt well to indoor environments—if given the right conditions. This article breaks down the best practices for growing lilies indoors and outdoors so you can decide what works best for your space and gardening goals.
What Are Lilies?
Lilies belong to the genus Lilium, a group of flowering plants known for their large, showy blooms. They come in a variety of colors including white, orange, pink, red, and yellow, and are often associated with purity, renewal, and celebration.
Some of the most popular types of lilies include:
- Asiatic lilies – early bloomers, hardy and colorful
- Oriental lilies – larger blooms, known for intense fragrance
- Trumpet lilies – tall with trumpet-shaped flowers
- Easter lilies – popular around spring holidays, often grown indoors
Each variety has different growth habits and care needs, which influence whether it’s better suited to indoor or outdoor growing.
Are Lilies Better Suited for Outdoors?
Outdoor Lilies Thrive in Natural Conditions
In general, most lilies are outdoor plants. They are perennials that flourish in garden beds, borders, and containers on patios or balconies. These conditions allow them to receive:
- Full sunlight (at least 6 hours per day)
- Good air circulation
- Well-drained soil
Lilies planted outdoors often produce larger, more robust blooms than those grown inside.
Benefits of Growing Lilies Outdoors
- Natural Pollination: Bees and butterflies help pollinate outdoor lilies.
- Room to Grow: Garden soil allows bulbs to expand and multiply.
- Seasonal Cycle: Outdoor lilies experience a natural dormancy period, which is essential for healthy regrowth.
Outdoor Planting Tips
- Plant bulbs in early spring or fall.
- Ensure the soil is well-draining and slightly acidic to neutral.
- Mulch in winter to protect from frost.
Can Lilies Be Grown Indoors?
Some Lilies Adapt Well Indoors
Yes, certain lilies can be grown indoors, especially if you want to enjoy their beauty year-round or lack outdoor space. The Easter lily (Lilium longiflorum) is one of the most common indoor lilies, especially during springtime.
Best Lily Varieties for Indoor Growing
- Easter lilies
- Asiatic lilies (in dwarf or compact forms)
- Peace lilies (Note: Peace lilies are not true lilies but are popular indoor plants often confused with them)
Indoor Lily Care Requirements
Growing lilies indoors takes a bit more effort to mimic their natural environment:
- Light: Place in a sunny window or under grow lights. They need at least 6 hours of light daily.
- Temperature: Keep in a cool room (60–70°F) to extend bloom time.
- Watering: Water when the top inch of soil feels dry. Avoid overwatering to prevent root rot.
- Potting: Use a well-draining potting mix in a container with drainage holes.
Tips for Indoor Success
- Rotate the pot regularly for even light exposure.
- Use a stake if the stems grow tall and heavy.
- After blooming, cut back the flowers but keep the foliage until it yellows.

Should You Move Lilies Indoors for Winter?
If you live in a colder climate, you might consider overwintering lilies indoors to protect the bulbs from freezing. Here’s how:
- After the first frost, dig up the bulbs.
- Clean off excess soil and let them dry.
- Store in a cool, dark, and dry location (like a basement or garage) in peat moss or paper bags.
- Replant in spring when the ground has thawed.
Common Mistakes to Avoid
Whether growing indoors or outdoors, avoid these pitfalls:
- Overwatering – leads to bulb rot
- Poor drainage – soggy soil suffocates roots
- Insufficient light – causes weak, leggy growth
- Crowded bulbs – limits air circulation and blooming
Conclusion: Where Should You Grow Your Lilies?
So, are lilies indoor or outdoor plants? The answer is: both—depending on the variety and your environment.
- For lush, low-maintenance blooms, outdoor lilies in a sunny garden are the way to go.
- If you love having fresh flowers indoors or don’t have a yard, indoor lilies can brighten up your home with some extra care.
Whether inside or outside, these elegant flowers reward you with stunning beauty and intoxicating fragrance—just give them the environment they need to thrive.
