For indoor plant lovers and beginner gardeners, ferns are a go-to favorite thanks to their lush greenery and soft, tropical vibe. Among the many types of ferns available, the Bird’s Nest Fern (Asplenium nidus) and the Blue Star Fern (Phlebodium aureum) are often compared—and frequently confused. Their similar arching forms, striking foliage, and love for humidity make them popular choices for bathrooms, shaded shelves, and plant corners alike. But despite their surface-level resemblance, these two ferns have distinct differences in appearance, care needs, and overall growth habit that can make or break your plant success indoors.
Whether you’re browsing a plant shop and debating which to bring home, or you’re unsure which one you already own, this side-by-side comparison will help you quickly and confidently grasp the differences between the Bird’s Nest and Blue Star Ferns—and find the one that’s just right for your space.

Key Differences Explained
1. Visual and Structural Differences
The most immediate and noticeable difference between these two ferns is the appearance of their fronds. The Bird’s Nest Fern forms thick, strap-like, undivided fronds that radiate symmetrically from a center, forming a tidy, upright rosette. Its leaf margins are often gently rippled and glossy—giving it an elegant, architectural look perfect for minimalist aesthetics or statement planters.
In contrast, the Blue Star Fern has a much looser, more casual growth habit. Its fronds are deeply lobed, giving them a feathery or wavy shape. Their hallmark coloring—blue-green or silvery gray—makes this plant particularly attractive under soft lighting. Instead of a central rosette, the Blue Star’s fronds grow along meandering rhizomes (horizontal stems) that creep along the soil surface. These rhizomes are covered in golden-brown fuzz, which can charm or confuse first-time owners.
2. Growth Habit and Space Considerations
If you’re looking for a neat, vertical specimen that stays put, the Bird’s Nest Fern delivers. Its self-contained rosette makes it well-suited for compact pots and shelves. As slow to moderately growing plants, they maintain their shape with little fuss for years. Their controlled form is ideal for interior decorators or minimalists wanting a clean, sculptural plant.
The Blue Star Fern’s growth is more exploratory. Over time, it can stretch outward from its pot via spreading rhizomes, eventually filling or even overflowing containers. This habit makes it ideal for hanging baskets, wide shallow pots, or as part of a lush fern collection where its wide spread can be shown off. It also tends to grow slightly faster when conditions are right, especially with boosted humidity and consistent moisture.
3. Tolerance of Indoor Environments
Bird’s Nest Ferns are humidity lovers. While they can tolerate average room humidity (40–50%), they truly thrive in high humidity environments—think bathrooms or kitchens with 60–80% humidity. They dislike dry air and should be placed away from heaters or draughty windows. Their fronds are thick and leathery but sensitive to overwatering or direct misting into the crown, which can cause rot (Gilman & Watson, 2014).
Blue Star Ferns, on the other hand, are somewhat tougher when it comes to fluctuating humidity. While they still appreciate a humidity level above 50%, they tolerate drier conditions better than most other ferns. They also aren’t as fussy with watering and will forgive a missed schedule now and then—even enjoying slightly drier topsoil between waterings. This adaptability makes them more manageable for beginners or inconsistent waterers.
4. Light Needs and Placement Flexibility
Both ferns prefer indirect light, but the Blue Star is notably more tolerant of low-light conditions. It can comfortably survive in rooms with north-facing windows or dimmer back rooms, making it attractive for apartments or offices with limited sunlight (Florida Master Gardener Program, 2022). The Bird’s Nest requires brighter indirect light and suffers in dim corners, showing yellowing fronds or drooping growth when light is insufficient.
Which One Should You Choose?
Choosing between the Bird’s Nest Fern and the Blue Star Fern depends less on what looks prettier—and more on your growing conditions and experience level. Here’s how to decide:
- Best for Beginners: Blue Star Fern—tolerates lower light and humidity, forgiving growth habits.
- For Statement Decor: Bird’s Nest Fern—sleek, symmetrical shape and bold texture perfect for a modern interior.
- Best for Small Apartments: Bird’s Nest Fern—compact and slow-growing, great for confined spaces.
- Low Light Homes: Blue Star Fern—thrives even in shadier rooms and northern light.
- Pet-Friendly Households: Both are non-toxic and safe for cats and dogs (ASPCA, 2023).
- People Who Travel or Forget to Water: Blue Star Fern—less demanding when it comes to watering frequency and humidity levels.
Final Thoughts
Both the Bird’s Nest and Blue Star Fern offer fern-lovers a rewarding indoor plant experience. While they share lush textures and tropical origins, their growth habits and maintenance needs distinguish them in helpful ways. The Bird’s Nest, with its upright, glossy waves, is best for those seeking elegance, structure, and a good light source. The Blue Star, with its relaxed form and dreamy blue-green fronds, brings a bit of the wild into the home—and won’t punish you for missing a watering day.
Know your space, your level of commitment, and your lighting conditions, and you’ll find that choosing between these two stellar ferns becomes a breeze.
