Popular South Florida ferns for the landscape include macho, foxtail, Boston, holly, fishtail, wart, and asparagus fern.
Garden ferns can work as graceful groundcovers for shade.
They're effective for filling in around taller plants - hiding the legginess of a mature cordyline (Ti plant), for instance, or surrounding a tree or palm.
Ferns can also add lush greenery to bare spots under trees. Some South Florida ferns can take the place of foundation plants, and a few work as front-of-the-border plants.
They even make excellent
accents with cut flowers from the garden, and are, of course, just
stellar in hanging baskets. There's even a gorgeous tree fern if you have plenty of room.
Ferns generally spread via underground runners...some spread all over the place, others not so much.
Each has its own personality - choose well for size and spread. Some may work for your landscape and others may not.
take full to partial shade unless noted. All do well in Zone 10 - cold
hardy ferns for Zone 9B are noted. All South Florida ferns can be grown
as container plants and brought in during winter in Zone 9B.
Macho fern (Nephrolepis biserrata)
A big bold fern that makes an impressive statement. Sometimes referred to as Giant Sword Fern.
Fast grower to about 3 feet tall. Native fern. Spreads.
LANDSCAPE USES: groundcover, foundation planting, surrounding trees, camouflage for leggy plants behind it, shade garden accent
Foxtail fern (Asparagus densiflorus 'Myers')
Soft tufts on a cold hardy plant. Amazingly tough in spite of its delicate good looks. Cold hardy and moderately salt-tolerant.
Grows about 2 feet tall in sun or shade. Spreads very little. Considered a deer-resistant plant.
LANDSCAPE USES: groundcover, front of the border, lining a walkway, foundation plant, garden accent
Boston fern (Nephrolepis exaltata)
A classic among ferns. Sometimes referred to as Sword Fern, this is the one that loves growing on Canary Island date palms.
Quickly fills in an area and can be invasive so use it in a well-defined area. Cold hardy. Fast grower to 2 to 2-1/2 feet tall. Native fern. Spreads. Said to be deer-resistant.
LANDSCAPE USES: groundcover, filler under trees
Holly fern (Cyrtomium falcatum 'Rochfordianum')
Cold tolerant beauty with glossy, deep green fronds. Slow grower to about 2 feet tall.
Usually not a lush, dense fern, more of an accent plant. For groundcover group plants fairly close together. Doesn't spread. Considered a deer-resistant plant.
LANDSCAPE USES: accent plant, front of the border, groundcover for a small area
Wart fern (Microsorum scolopendrium)
Low grower that gives a unique texture to the garden. Slow growing to an overall height less than a foot tall.
The name derives from the little brown bumps on the backs of the leaves. Spreads but very well mannered.
LANDSCAPE USES: groundcover
Fishtail fern (Nephrolepis falcata)
Very pretty fern with a ruffled texture. Fast grower to 2-1/2 to 3 feet tall.
Fills in an area quickly. Native fern. Spreads but can be contained.
LANDSCAPE USES: groundcover, foundation planting, lining a path or walk, surrounding trees, camouflage for leggy plants behind it, shade garden accent
Asparagus fern (Asparagus densiflorus 'Sprengeri')
Pretty, cold hardy and salt tolerant, but also prickly, invasive and hard to get rid of. Grows to about 2 feet tall in sun or shade.
Only plant if nothing else works for hard to mow areas and embankments where soil erosion is a problem. It can be mowed or weed-whacked low to look more uniform. Spreads, very invasive. Said to be deer-resistant.
LANDSCAPE USES: groundcover for impossible areas, soil erosion control
Add top soil to the hole when planting in very dry sandy areas.
Water regularly but don't overdo it. South Florida ferns like humidity and regular moisture but they're not wild about "wet feet."
No trimming is needed for most, other than to remove a dead frond now and then. You may at some point have to thin out a fern bed if it gets too wild-looking and overgrown.
Fertilize once or twice a year (spring and late summer) with a controlled release fertilizer.
Most ferns can be placed 2 to 3 feet apart.
Come in from walks and drives 2 feet for smaller, slower ferns like wart and holly. The others should be situated 2-1/2 to 3 feet away from areas of foot or vehicle traffic.
Many South Florida ferns make wonderful container plants, especially beautiful in hanging baskets.
