Are Ferns Indoor or Outdoor Plants? Everything You Need to Know
Ferns are a favorite among plant lovers for their lush greenery and timeless elegance. But if you’re wondering whether ferns belong indoors or outdoors, you’re not alone. These ancient plants thrive in both environments, but the key lies in choosing the right type and giving them the care they need.
In this article, we’ll explore whether ferns are best suited as indoor houseplants or outdoor garden companions, how to care for them in each setting, and the best fern varieties for your space.
What Are Ferns?
Ferns are non-flowering, leafy plants that reproduce through spores instead of seeds. With over 10,000 known species, they’re one of the oldest plant groups on Earth—dating back over 360 million years.
Common features of ferns include:
- Feathery, green fronds
- A love for moist, shady conditions
- Ability to purify indoor air
Because of their adaptability, ferns have made their way into both homes and gardens.
Are Ferns Good Indoor Plants?
Yes, Many Ferns Thrive Indoors
Certain fern varieties make excellent indoor plants, especially for those looking to bring a bit of the rainforest into their home.
Benefits of indoor ferns:
- Improve air quality
- Add a lush, tropical aesthetic
- Thrive in low-light or indirect light conditions
Popular indoor ferns include:
- Boston Fern (Nephrolepis exaltata): Easy to care for, loves humidity
- Maidenhair Fern (Adiantum): Delicate and elegant, but a bit more finicky
- Bird’s Nest Fern (Asplenium nidus): Bold, crinkly leaves, tolerant of lower humidity
Indoor fern care tips:
- Keep soil moist but not soggy
- Mist regularly or use a humidifier
- Place near a window with filtered sunlight
- Avoid drafts and direct heat sources
Ferns can add life to bathrooms, kitchens, and shady corners—just make sure to mimic their natural habitat.
Can Ferns Be Grown Outdoors?
Absolutely—Ferns Love Outdoor Gardens Too
Many fern species thrive in shady outdoor spaces, especially those that mimic their natural forest environments.
Ideal outdoor conditions:
- Partial to full shade
- Moist, well-drained soil
- Protection from harsh sun and wind
Top outdoor fern varieties:
- Ostrich Fern (Matteuccia struthiopteris): Hardy and dramatic
- Lady Fern (Athyrium filix-femina): Lacy, with vibrant green foliage
- Japanese Painted Fern (Athyrium niponicum): Silvery tones, ornamental appeal
Ferns make excellent ground cover, border plants, or woodland accents. They’re also great for adding texture and movement to your landscape.
Key Differences: Indoor vs. Outdoor Ferns
| Feature | Indoor Ferns | Outdoor Ferns |
|---|---|---|
| Light | Indirect or low light | Shade or filtered sunlight |
| Humidity | Higher humidity preferred | Adapted to local outdoor humidity |
| Temperature | Consistent indoor temps | Must tolerate seasonal changes |
| Varieties | Boston, Maidenhair, Bird’s Nest | Ostrich, Lady, Japanese Painted |
Understanding these differences helps you pick the right fern for your environment and provide the care it needs to flourish.
Can You Move Ferns Indoors and Outdoors?
Yes, With Proper Care and Timing
Some ferns are flexible enough to live both indoors and outdoors, but transitioning them requires care.
Tips for moving ferns between indoors and outdoors:
- Acclimate slowly: Introduce to new lighting and temperatures gradually
- Watch the weather: Avoid moving them during extreme heat, cold, or dry spells
- Pest check: Inspect for insects before bringing them indoors
- Container ferns: Use pots with drainage holes to move easily between spaces
This flexibility makes ferns a great option for seasonal plant displays or patios.
Best Practices for Fern Care (Anywhere)
Regardless of where your ferns live, some basic care rules apply:
- Keep soil evenly moist
- Use well-draining, organic-rich soil
- Avoid direct sunlight that can scorch fronds
- Feed lightly with a balanced, diluted fertilizer during growing season
- Prune dead or yellowing fronds to encourage new growth
Pro Tip: Use a pebble tray or humidifier indoors to maintain the high humidity ferns love.
Final Verdict: Are Ferns Indoor or Outdoor Plants?
Ferns are both indoor and outdoor plants—it just depends on the variety and your climate. With the right conditions, they’ll thrive in a shady garden or a cozy corner of your living room.
Whether you’re a beginner plant parent or an experienced gardener, ferns are a low-maintenance, visually appealing addition to your plant collection.
