If you love the lush, tropical look of bird’s nest ferns but want to ensure your home is safe for children and pets, this list is for you. Bird’s nest ferns (Asplenium nidus) are popular for their wavy, bright green fronds and ease of care, but finding similar ferns that are non-toxic can be tricky. Below are ten non-poisonous ferns that resemble bird’s nest fern in appearance or growth habit, making them excellent alternatives for indoor or shaded outdoor spaces.
1. Boston Fern (Nephrolepis exaltata)
Boston ferns are classic houseplants known for their arching, feather-like fronds and vibrant green color. Unlike bird’s nest ferns, Boston ferns have a more delicate, lacy appearance, but their lush, full foliage creates a similar tropical vibe. Importantly, Boston ferns are non-toxic to cats, dogs, and humans, making them a safe choice for homes with pets or children.
2. Rabbit’s Foot Fern (Davallia fejeensis)
Rabbit’s foot fern features long, narrow fronds that can look somewhat like bird’s nest fern leaves but with a more delicate texture. Its rhizomes grow over the pot edge, resembling furry rabbit feet, which adds unique visual interest. This fern is also non-toxic and thrives in indirect light with moderate humidity, making it a suitable pet-friendly indoor plant.
3. Maidenhair Fern (Adiantum raddianum)
Maidenhair ferns have small, fan-shaped leaflets on wiry black stems, offering a refined, airy look that contrasts with the broad fronds of bird’s nest ferns but still provides lush greenery. They prefer consistent moisture and indirect light. This species is non-toxic and often recommended for homes with pets due to its safe profile.
4. Button Fern (Pellaea rotundifolia)
Button ferns have small, rounded leaflets that form compact, arching fronds. While their texture differs from the broad, wavy leaves of bird’s nest ferns, button ferns share a similar growth habit and create dense, attractive foliage. They are non-toxic and tolerate indoor environments well, requiring moderate watering and bright, indirect light.
5. Staghorn Fern (Platycerium bifurcatum)
Staghorn ferns are epiphytic ferns with uniquely shaped fronds that resemble antlers. Although their form is quite different from bird’s nest ferns, both share a tropical aesthetic and can be mounted on boards or hung, adding versatility to your indoor garden. Staghorn ferns are non-toxic and safe for pets, thriving in bright, indirect light and high humidity.
6. Korean Rock Fern (Polystichum tsus-simense)
This compact fern has glossy, dark green fronds with a dense, tufted habit somewhat reminiscent of bird’s nest ferns’ rosette shape. It tolerates lower light conditions and prefers well-draining soil, making it a low-maintenance indoor fern. Korean rock fern is non-toxic to pets and adds a sophisticated, lush look to shaded areas.
7. Asparagus Fern (Asparagus densiflorus ‘Sprengeri’)
Though not a true fern, asparagus fern mimics the fine, feathery foliage that complements bird’s nest fern’s broad leaves when paired together. It is non-toxic to humans and generally considered safe for pets, though ingestion in large amounts may cause mild irritation. This plant thrives in bright, indirect light and is drought tolerant, making it easy to care for indoors.
8. Holly Fern (Cyrtomium falcatum)
Holly ferns have glossy, dark green fronds with a leathery texture and distinctive serrated edges, giving them a structured look that contrasts nicely with the softer bird’s nest fern. It tolerates low light and dry indoor air better than many ferns. Holly fern is non-toxic and a great option for pet owners seeking a hardy, attractive fern.
9. Kimberly Queen Fern (Nephrolepis obliterata)
Kimberly Queen fern has upright, sword-shaped fronds that are thicker and stiffer than Boston ferns but still lush and green. Its growth habit is more vertical compared to the rosette form of bird’s nest fern but offers similar tropical appeal. This fern is non-toxic, drought tolerant, and well-suited for indoor environments.
10. Lemon Button Fern (Nephrolepis cordifolia ‘Duffii’)
Lemon button fern features small, rounded leaflets densely packed on arching fronds, giving it a compact and bushy appearance. It resembles bird’s nest fern in providing vibrant greenery but with a finer texture and smaller size. It is non-toxic and prefers indirect light with moderate humidity, making it a safe and attractive houseplant.
How to Choose
When selecting a non-poisonous fern similar to bird’s nest fern, consider your lighting conditions first—most ferns prefer indirect or filtered light and will suffer in direct sun. Humidity is another key factor; bird’s nest ferns thrive in high humidity, so if your home is dry, choose hardier ferns like holly fern or Korean rock fern. Growth habit and size matter too: if you want a similar rosette shape, Korean rock fern or button fern might suit you best, whereas Boston or Kimberly Queen ferns offer more arching or upright fronds. Lastly, consider pet safety and ease of care—while all listed ferns are non-toxic, some may require more consistent watering or humidity. Matching these factors to your environment and lifestyle will help you pick the best fern for your space.
