This May, a true classic is stepping into the spotlight as Air-Purifying Plant of the Month: Nephrolepis, also known as the Curly Fern. With its playful, curled leaves, this lush green plant is not only visually appealing, but it also helps to keep the air clean and fresh. In short: the perfect plant for anyone who loves greenery and a healthier living environment.
What makes the Nephrolepis special?
The Nephrolepis , like all plants in the Air So Pure range, is air-purifying. It naturally removes harmful substances like formaldehyde from the air. No plugs or filters required—just pure plant power through its leaves and roots. The Boston fern is not only a charming addition to any space, it also works quietly in the background to improve air quality at home or at work—no green thumb required.
What’s also striking about the Nephrolepis is its full, airy foliage. Its fronds grow in soft curls or arches, giving it a cheerful and relaxed appearance. You can hang it in a decorative plant hanger or simply place it in a pot on a shelf or in a cozy corner. It fits in just about anywhere—living room, bedroom, office, or classroom. Thanks to its shape and growth, it quickly becomes a lush, vibrant plant that adds a natural, cozy feel to your interior.
How to care for the Nephrolepis
You don’t need to be a plant expert to keep the Air-Purifying Plant of the Month (Curly fern) happy and healthy. A few simple tips go a long way:
- Light: Place the plant in a spot with plenty of daylight, but avoid direct sunlight. Partial shade is ideal.
- Water: Keep the soil lightly moist. It’s better to water a little more often with small amounts than to overwater in one go.
- Humidity: The Curly fern thrives in humid air—just like its natural tropical habitat. Mist it now and then to make it feel right at home.
- Nutrition: During the growing season (spring and summer), you can feed the plant once a month with diluted liquid fertilizer—preferably one made for green houseplants. No need to fertilize in autumn and winter.
- Pruning: Yellowed or dried-out fronds can be trimmed off at the base. This keeps the plant fresh and encourages new growth. If the plant gets too large, you can also trim it back slightly.
Is the Nephrolepis (Curly fern) toxic?
Good news for pet owners and parents: the Nephrolepis is non-toxic. So no need to worry if your cat or dog takes a curious nibble. Still, it’s wise to keep all plants out of reach of persistent chewers.

Different types of Nephrolepis
The Nephrolepis genus includes several species, each with its own unique charm. The most well-known varieties are Nephrolepis Green Lady and Nephrolepis Duffii.

That makes this air-purifying plant perfect for any setting—from a cozy home office to a spacious living area.
Which Nephrolepis suits you best: Green Lady, Macho, or Duffii?
The Nephrolepis Green Lady is perhaps the best-known variety. It has full, elegantly arching fronds that create a lush, woodland feel. It grows quickly yet remains compact, making it perfect for indoor spaces. Strong and adaptable, it fits beautifully in almost any interior.
The Nephrolepis Duffii, also known as the Lemon Button Fern, has finer, more compact leaves and a slightly upright growth habit. This subtle variety is ideal for smaller rooms or as part of a plant mix. Both Green Lady and Duffii are highly air-purifying, non-toxic, and easy to care for—so you can’t go wrong.
The Nephrolepis Macho is the giant of the fern family. With its large, broad fronds, it can grow up to 1.5 meters tall and wide. It’s a true showstopper—perfect for large living rooms, office spaces, or entryways where you want to make a bold green statement.
Whichever variety you choose, they’re all highly air-purifying, safe, and low maintenance. A healthy and beautiful choice for your space!
