Beautiful and Unusual Fern Varieties for the Garden

Amp up the shade with these unique evergreen stunners

Fine Gardening - Issue 165
When I first fell in love with the then-rare autumn fern (Dryopteris erythrosora, USDA Hardiness Zones 5–9) back in the late 1960s, ferns were strangers in the garden, with but a handful of natives offered for sale and little recognition of their value by designers or even devoted gardeners. All of that has changed, and there are now selections for every purpose, from diminutive rock-garden specimens to ground covers to tall sentinels that create focal points. Some are evergreen and some deciduous, some will take sun but most prefer shade, and some will tolerate drought while others prefer wet and boggy locations. The fronds come in endless versions of texture and form—lacy, graceful, bold, soft, upright, or lax—as well as varying shades of color, including rosy hues. The following ferns are among my many favorites. All are evergreen, so they’ll charm you year-round. Please note that the sizes are variable depending on zone, soil, water, and exposure.

Jeweled chain fern is unique

Name: Woodwardia unigemmata

Zones: 8 to 10

Size: Stems and fronds up to 6 feet long, cascading

Conditions: Partial shade; moist soil

Jeweled chain fern certainly is a gem, with showy, arching fronds that emerge in brilliant shades of red and readily cascade over a wall or slope. Each frond grows up to 6 feet long and is tipped with a willing-to-root bulbil that the frond is attempting to bring down to accepting soil. These bulbils can be picked for propagating late in the season when they are plump. Place them on moist but not wet soil in a small pot, cover the pot with a clear plastic cup, put it under lights indoors, and wait for your reward. This species breaks the monotony of upright plants and is especially attractive in giving motion to a hillside.

Sunset fern lives up to its name

Name: Dryopteris lepidopoda

Zones: 6 to 9

Size: 15 to 24 inches tall and 2 feet wide

Conditions: Light shade; humus-rich, moist but not wet soil

Common names vary in usefulness, but this moniker is a perfect choice for this stunning and adaptable species with its warmly colored pink/salmon/red/yellow, vase-shaped spring growth. Colorful new fronds continue to be produced throughout summer, giving a continuous show and glow to a lightly shaded area. With its reliably evergreen countenance, sunset fern makes an elegant edging to define a woodland path or a beckoning focal point to draw folks into a garden. It resembles the colorful Wallich’s wood fern (Dryopteris wallichiana, Zones 5–7) but is smaller in stature and a tad more cold tolerant. Relatively new in cultivation, it can be difficult to find on the market, but it is worth every effort, even for a nonfern enthusiast.

Upside-down fern forms a feathery vase

Name: Arachniodes standishii

Zones: 5 to 9

Size: 2 to 3 feet tall and 2 feet wide

Conditions: Partial to full shade; moist, loose, organic soil

Upside-down fern forms a sturdy, vase-shaped display of delicately patterned, lacy foliage in light shade. The prominent veins on top of the fronds give this fern its name. There are two types: The Korean version is somewhat larger than the Japanese version and is the most common one in cultivation. It makes an attractive contrast to heavier-looking evergreens.

Asian saber fern stands up to snow

Name: Polystichum neolobatum

Zones: 5 to 8

Size: 18 to 30 inches tall and 2 feet wide

Conditions: Light to deep shade; moist soil

Not only is Asian saber fern evergreen, but it is also one of only a few ferns whose fronds will maintain their upright habit after being buried in a foot or so of snow. The narrow fronds are glossy and noticeably prickly to the touch. The new spring growth ignites interest with fiddle­head clusters that are thickly coated with ornamental russet scales. It will burn in the sun and does not like to dry out, but otherwise, this fern can be sited in almost any depth of shade.

They almost take care of themselves

While ferns are low maintenance, they aren’t completely without needs. As a fern grower, I get asked the same few questions over and over again:

When should I plant ferns?

Ferns can be planted whenever the soil is not frozen, but the best time is in early fall, giving them time to get established before the stress of winter. The essential condition is that ferns be kept moist while they acclimate to their new home and their roots get established. Even drought-tolerant types need water throughout their first summer.

Do they need to be fertilized?

Ferns should be planted in a loose mix of composted soil with good drainage. Given the proper setting, fertilizer is not necessary, although I allow fallen tree leaves to enrich the soil by remaining as mulch around the plants. And never add lime to the fern garden.

Can I divide them?

Ferns that creep or develop multiple crowns (photo, above) are candidates for division. The ideal time is in fall to give the transplants time to establish without the stress of heat and before the stress of cold. Using a sharp spade, carefully cut away the offspring. Replant divisions in good soil and partial shade, and keep them watered.

Should I cut back the fronds in spring?

Deciduous ferns are self-grooming and will lay their fronds down in fall. Evergreen fern fronds, however, will continue to produce food all winter, so it is best to leave them be until just prior to their new growth in spring. They can then be whacked off, but be careful not to cut any new fronds.

Do they have any pests?

Ferns, fortunately, have few problems with pests. Slugs and snails will find vulnerable new growth appetizing and should be discouraged with early applications of slug bait. Distribute the bait at a distance so as not to attract the predators to your delicacies. Aphids are rare but, again, are attracted to delicate new growth. They can be repelled with a gentle spray from your hose. Deer don’t usually bother ferns; rabbits, however, consider ferns and everything else in the garden their personal salad bars.

Chilean hard fern is an architectural wonder

Name: Blechnum chilense

Zones: 8 to 11

Size: 3 to 5 feet tall, spreading indefinitely

Conditions: Partial to deep shade; moist, well-drained soil

Chileans call this fern las costillas de la vaca, or ribs of the cow—an apt description. Chilean hard fern is superbly architectural. Its glowing red new growth (which is more prominent if the fern is not fertilized and not in nutrient-rich soils) turns into upward-reaching, statuesque stalks of fronds. It will tolerate slightly dry shade but will not be as exuberant. And with its creeping rhizomes, it can, indeed, be robust when happy (so much so that it is not possible to define a width). It will spread enthusiastically but is not aggressive or invasive.

Siebold’s wood fern really is a fern

Name: Dryopteris sieboldii

Zones: 6 to 9

Size: 30 inches tall and wide

Conditions: Light shade; humus-rich, moist soil

Siebold’s wood fern is a plant with a distinguished and unique outline, prompting some visitors to ask, “Is that really a fern?” It’s a bold and highly ornamental conver­sation piece that does especially well when encouraged by warmth. In cooler areas, it expands rather late in the season and is somewhat frugal in producing its spectacular new foliage. The fronds look like long daggers and are a pastel blue-green—especially attractive when set among driftwood or mossy logs or when backed by a foliar foil that is light or very dark.

Fortune’s holly fern is as tough as it is bold

Name: Cyrtomium fortunei

Zones: 5 to 10

Size: 15 inches tall and 18 inches wide

Conditions: Partial to full shade; fertile, humus-rich, moist, well-drained soil

Fortune’s holly fern is the most cold tolerant of the holly ferns (Cyrtomium spp., Zones 5–11). The holly allusion refers to the unusual shape of the fern’s pinnae, which, with some imagination, can be said to resemble holly leaves. It does give the genus an appearance far different from the stereotypical lace-fronded fern and makes this species an excellent choice for providing an interesting contrast to the graceful appearance of more traditional ferns. This is an excellent choice for deep shade, where its pale green evergreen foliar rosettes bring a lightness to their surroundings. As with many ferns, it makes a nice foil for spring-blooming flowers. And when placed out of the sun, it also makes an easy-to-maintain indoor plant.

Himalayan maidenhair fern forms a frilly carpet

Name: Adiantum venustum

Zones: 5 (with protection) to 9

Size: 12 to 15 inches tall, creeping indefinitely

Conditions: Partial shade; moist, well-drained soil

Unlike our more familiar clump-forming native maidenhair ferns (Adiantum aleuticum and A. pedatum, Zones 3–8), this species will creep slowly but not aggressively to form an elegant, fine-textured, evergreen carpet. Despite its delicate appearance, Himalayan maidenhair fern is not fussy about soil and habitat, but as with most ferns, it flourishes in filtered shade and composted soil. In spring, new fronds appear first as pale rosy tendrils that unfurl slowly and aren’t usually affected by late frosts. While not necessary for the health of the plant, the old fronds can be cut back before spring to tidy up the plant. This fern can be divided in fall, but small pieces do not reestablish well, so take substantial divisions.
