Resurrection Fern
A little native fern that grows ON tree limbs and rocks with no soil - and performs a genuine resurrection: it curls up crispy brown and 'dead' in drought, then unfurls green within a day of rain, over and over, for decades.
Safety notes Resurrection fern is a harmless native epiphytic fern, not toxic and not a parasite - it perches on tree bark and rock and takes nothing from its host. Its 'dead,' curled brown state is normal dormancy, not disease. It is grown as a living curiosity, not eaten; like many ferns it is not intended as food.
Overview
Resurrection fern (Pleopeltis polypodioides) is a small, tough, and quietly astonishing native fern of the Southern woods, best known as the green carpet on the great horizontal limbs of live oaks. Like the air plants it often shares those limbs with, it is an epiphyte: it grows entirely on the surface of tree bark, fallen logs, and rocks, with no soil, gripping its perch with a creeping surface rhizome and drawing water and nutrients from rain, dew, humidity, and the crumbs of debris caught in bark crevices. It is not a moss and not a parasite - it takes nothing from the tree, using it only as a place to live.

When to plant
Nothing is open today. Spring transplanting opens 6 months, Apr 10 to Aug 8.
- Transplant Apr 10 – Aug 8 Opens in 173 daysAbout at to 17 weeks after your last frost (Apr 10 here)Not truly planted - press a piece of the creeping rhizome onto a shaded, mossy limb, log, or rock in the warm, moist season and let it grip. No soil, no pot, no deep roots. Spring into summer, with reliable moisture, helps it anchor fastest.
Frost here: last around Apr 10 (Mar 27 to Apr 24 most years), first around Oct 25. Zone averages, your own yard may run a week or two either way.

Care at this stage
-
Press a rhizome piece onto a mossy limb or rock
There is no soil. Lay a piece of the creeping surface rhizome (with a few fronds) against a shaded, rough, ideally mossy tree limb, log, or rock, and tie or pin it lightly until it grips. Its wiry rhizome creeps along the surface and anchors itself; a damp, mossy oak limb is the classic home. Never bury it - it lives on the surface. Take that starting piece from your own trees or with the owner's permission, never off wild or public ones.
-
Keep it shaded and humid while it grips on
Resurrection fern absorbs water from rain, dew, and humidity, plus the thin layer of debris caught in bark crevices - it has no deep roots. Keep it in shade and mist it while the rhizome takes hold; it will green up with moisture and curl up when dry, which is completely normal even as it establishes.
Months are typical seasonal windows; climate, variety, and plant age can shift them.
Watch out for
3 to know. None are high-risk for Resurrection Fern. 1 is active in October.
Air-Pollution SensitivitySeverity Low DisordernowSeason: year-roundSparse, declining epiphyte cover in heavily polluted areas despite shade and moisture.
Sparse, declining epiphyte cover in heavily polluted areas despite shade and moisture.
None specific; it recovers where air and moisture conditions are good. Treat thriving epiphytes as a sign of healthy air.
Little can be done about ambient air quality; site plants away from concentrated pollution sources where possible.
Like many epiphytes that absorb everything through their surfaces, resurrection fern can be sensitive to heavy air pollution, tending to thin out in badly polluted urban air - which also makes healthy epiphytes a rough indicator of clean air.
Mistaken for Dead & RemovedSeverity Low DisorderSeason: Jan, Feb, Jun, Jul, Aug, Nov, DecAn impulse to 'rescue' or remove crispy gray-brown fronds during a dry or cold spell.
An impulse to 'rescue' or remove crispy gray-brown fronds during a dry or cold spell.
Do nothing but wait for moisture (or mist it). Fronds rehydrate and unfurl green; there is nothing to cure.
Understand the resurrection cycle: brown and curled is normal dormancy, not death. Leave it be; it revives within a day of rain.
The most common 'threat' is human: in its normal curled, brown, desiccated dormancy the fern looks dead or diseased, and people strip it off, drown it, or replace it - when it would have revived green with the next rain.
Prolonged Drought & Sun ExposureSeverity Low DisorderSeason: Jun–SepFronds that stay brown and crumbling and never green up after good rain, especially on hot, sun-baked, exposed surfaces.
Fronds that stay brown and crumbling and never green up after good rain, especially on hot, sun-baked, exposed surfaces.
Move survivors to shadier, moister conditions; there is no reviving genuinely dead tissue, but healthy rhizome pieces will regrow.
Site it in shade to part shade on a humid, moisture-catching surface; avoid hot, dry, fully exposed spots; mist in dry climates.
Extraordinarily drought-tolerant but not immortal: on a hot, fully exposed, chronically bone-dry perch with no rehydration for a very long time, even resurrection fern can eventually fail to revive.
Good & bad neighbors

Live Oak (Quercus virginiana)The signature host: resurrection fern carpets the broad, shaded, horizontal limbs of live oaks throughout the South, perching on the bark for support only and taking nothing from the tree.
-
The two share the same oak limbs constantly - resurrection fern as a green carpet on the bark, Spanish moss hanging in strands above it - a classic pair of harmless native epiphytes on one branch, both living without soil.
- Traditional pairings, thin evidence
-
Another epiphyte of the same Southern limbs - ball moss perched in tufts above, resurrection fern carpeting the bark below, both harmless passengers taking nothing from the host.
-
It grows on the bark of maples and other moist-woodland trees as well as oaks; a shaded, humid red maple limb can host a creeping mat over time.
-
Resurrection fern will colonize the rough, shaded bark of many hardwoods; a mature white oak's limbs make a good perch in humid, shaded conditions.
