Why You Should Fill Your Home with Ferns
There's a quiet revolution happening in the houseplant world, ferns are making a comeback. And it's not just the Boston and Maidenhair...many more fern varieties are slowly appearing in shops.
While everyone else is chasing the next trendy variegated monstera or rare aroid, those in the know are turning to an unfairly overlooked group of plants: ferns.
Ferns have an undeserved reputation for being difficult or boring, but once you discover the sheer variety available—from the reptilian texture of crocodile ferns to the ethereal delicacy of maidenhair—you'll wonder why you ever limited yourself to just one. When grouped together, their varied textures, forms, and shades of green create a layered, lush display that single specimens simply can't match.
Let's explore some of the most distinctive ferns you can bring into your home and why they deserve to be shown off in numbers.
Crocodile fern: textural drama
The crocodile fern (Microsorum musifolium) gets its name from the distinctive puckered texture of its leaves, which genuinely resembles crocodile skin. Each glossy, bright green frond is deeply quilted, creating incredible visual texture that catches light and shadow beautifully.
Unlike many ferns that cascade or spread, crocodile fern grows in an upright rosette, making it perfect for tabletops or shelves where you want structured interest. The leaves emerge in a gorgeous lime-green colour before maturing to deeper emerald, meaning you get multi-tonal interest even within a single plant.
In a grouped fern display, crocodile fern provides bold texture and a slightly more architectural form that contrasts beautifully with lacier, more delicate varieties.
Mother fern: the gift that keeps giving
Mother fern (Asplenium bulbiferum) is one of the most fascinating ferns you can grow because it literally produces baby plants along the edges of its mature fronds. These tiny plantlets will eventually drop off and root if conditions are right, or you can remove them and pot them up to expand your collection or share with friends.
The fronds themselves are feathery and finely divided, creating a soft, cloud-like appearance. The overall effect is delicate without being fussy, and the arching habit means mother fern works beautifully in hanging displays or on pedestals where the fronds can cascade naturally.
When you group mother ferns with other varieties, their fine texture provides wonderful contrast against bolder-leaved ferns, creating depth and visual complexity.
Asparagus fern: not actually a fern (but we love it anyway)
Technically asparagus fern (Asparagus setaceus or Asparagus densiflorus) isn't a true fern at all—it's in the asparagus family—but its delicate, needle-like foliage and cascading growth habit make it a perfect companion for true ferns in grouped displays.
The feathery plumes create an incredibly soft, airy texture that seems to float. There's something almost cloud-like about a healthy asparagus fern, and they grow with enviable vigour once established. Some varieties produce tiny white flowers and red berries as a bonus.
In a massed fern display, asparagus fern adds movement and an almost ethereal quality. The fine texture works particularly well alongside ferns with larger, more substantial fronds.
Boston fern: the classic for good reason
Boston fern (Nephrolepis exaltata) is probably the fern most people picture when they think "fern," and its popularity is entirely justified. Those gracefully arching fronds with their orderly rows of leaflets create instant lushness wherever they're placed.
What makes Boston ferns brilliant for massed displays is their generous size and cascading habit. They fill space beautifully and create that coveted "jungle" effect. Their bright, fresh green colour acts as a perfect backdrop for more unusual varieties.
Modern cultivars offer different frond shapes and sizes, from tightly ruffled to long and elegant, meaning you can even create variation within the Boston fern category alone. Group several together at different heights and you've got an instant green waterfall.
Maidenhair fern: delicate perfection
Maidenhair fern (Adiantum) is the plant that makes people stop and ask "what is that?" The tiny, fan-shaped leaflets on black wiry stems create an appearance unlike any other houseplant. There's something almost magical about the way they seem to float and shimmer with the slightest movement.
Yes, maidenhair ferns have a reputation for being temperamental—they despise dry air and forgetting to water them is not an option. But here's where the "en masse" approach actually helps: when you group humidity-loving ferns together, they create their own microclimate, each plant increasing the moisture in the air around its neighbours.
The delicate, almost lace-like texture of maidenhair provides the most beautiful contrast imaginable when paired with any bolder-leaved fern. The effect is genuinely stunning.
Hart's tongue fern: architectural elegance
Hart's tongue fern (Asplenium scolopendrium) breaks every fern stereotype. Instead of divided, feathery fronds, this British native produces smooth, glossy, strap-shaped leaves that emerge in a neat rosette. They're bold, architectural, and completely distinctive.
The leaves have a wonderful leathery texture and often develop wavy edges, adding movement without sacrificing their substantial presence. They're also one of the hardier ferns, tolerating cooler conditions than many tropical varieties.
In grouped displays, Hart's tongue fern provides structure and a completely different form that makes other ferns look even more delicate by comparison. The contrast is exactly what makes massed fern displays so visually compelling.
Blue star fern: subtle colour variation
Blue star fern (Phlebodium aureum) brings something unique to the fern family: colour. Well, a subtle blue-green colour that sets it apart from the standard emerald of most ferns. The fronds are deeply lobed, creating a dramatic silhouette, and they're covered in a slight silvery bloom that catches the light.
The fronds grow from thick, furry rhizomes that creep along the soil surface, adding another textural element to your display. Blue star fern has a more relaxed, spreading habit than some of the tidier varieties.
When grouped with greener ferns, that blue-grey tone creates wonderful depth and prevents your display from looking monotone. It's subtle variation that makes all the difference.
Bird's nest fern: rosettes of perfection
Bird's nest fern (Asplenium nidus) is another fern that defies the typical feathery stereotype. It produces smooth, glossy, tongue-shaped fronds that emerge from a central rosette, creating a sculptural form that's utterly distinctive.
The fronds are bright apple-green when young, maturing to a deeper shade, and they can grow impressively large given the right conditions. The central "nest" from which new fronds unfurl is genuinely fascinating to watch.
Like Hart's tongue fern, bird's nest fern provides architectural structure in grouped displays. Its bold, simple form makes an excellent anchor point around which to arrange more delicate varieties.
The power of the fern collection
Here's why grouping these ferns together creates such extraordinary impact: variety and repetition working in harmony.
When you display multiple ferns en masse, you're creating a tapestry of textures—smooth alongside ruffled, delicate beside bold, upright contrasting with cascading. Each individual variety looks more interesting because it's set against others. The glossy perfection of bird's nest fern becomes more striking when placed beside the feathery delicacy of maidenhair. The architectural Hart's tongue looks more dramatic when surrounded by the abundance of Boston fern.
There's also something psychologically satisfying about collections. A single beautiful object is lovely; many beautiful objects thoughtfully arranged together becomes something greater than the sum of its parts. It demonstrates intention, knowledge, dedication. A shelf of varied ferns tells visitors "this person knows their plants."
Styling your fern collection
The beauty of ferns is that they're remarkably flexible in their display options. Here are approaches that work brilliantly:
Shelf styling – Use varying heights with books, small stands, or upturned pots to create levels. Place trailing varieties like Boston and asparagus fern where they can cascade, architectural varieties like bird's nest in the centre or back, and delicate maidenhair where it can be appreciated up close.
Bathroom jungle – If you have a bathroom with decent light, it's genuinely the perfect fern location. The humidity from showers means even temperamental maidenhair will thrive. Group several ferns on a plant stand or shelving unit for instant spa vibes.
Grouped floor display – Use three to five larger ferns in complementary pots grouped in a corner or beside furniture. Vary the heights and forms—perhaps a tall Boston fern at the back, a medium bird's nest fern to one side, and a cascading asparagus fern at the front. The grouped mass creates far more impact than the same ferns scattered throughout a room.
Hanging collection – Install multiple hooks at varying heights and create a hanging fern display. The cascading varieties (Boston, mother, asparagus) are obvious choices, but don't overlook how striking an Osaka fern or blue star fern looks suspended in a hanging planter.
Windowsill line-up – A bright but not direct-sun windowsill can support a whole row of smaller ferns in matching pots. The repetition of containers unifies the display while the variety of ferns keeps it interesting.
Care considerations for your fern family
The wonderful thing about grouping ferns is that most share similar care requirements, making maintenance straightforward:
Humidity is everything – Ferns are humidity lovers, and grouping them helps create a more humid microclimate. Regular misting helps, but if you're serious about ferns, a small humidifier nearby is worth every penny.
Indirect light – Most ferns appreciate bright but indirect light. Too much direct sun scorches their delicate fronds, but too little light results in sparse, leggy growth.
Consistent moisture – Ferns generally dislike drying out completely. Check them regularly and water when the top of the compost feels just dry to the touch. Grouping them together means you can water your whole collection in one efficient round.
Good drainage – Despite loving moisture, ferns hate waterlogged roots. Ensure pots have drainage holes and the compost is moisture-retentive but free-draining.
The fact that these care requirements overlap makes building a fern collection genuinely practical—you're not juggling wildly different watering schedules or light requirements as you might be with a mixed houseplant collection.
Why now is the perfect time for ferns
In a houseplant world that's become obsessed with variegation, rare cultivars, and Instagram-worthy specimens with eye-watering price tags, there's something refreshingly accessible about ferns. They're widely available, reasonably priced, and offer genuine variety without requiring you to join waiting lists or take out a second mortgage.
They also bring a different aesthetic—lush, layered, green, alive. A collection of ferns creates atmosphere in a way that a scattered assortment of trendy plants simply doesn't. There's a cohesiveness, a theme, a sense of genuine curation.
