Symbolism & Meaning of Fern

Explore the meaning of the fern, its symbolism, myths, and folklore as part of the Celtic Tree Calendar (Reed – 28th October to 23rd November), alongside my fern illustrations.

The fern is a plant of mystery, protection, and hidden power - ancient, quiet, and deeply connected to unseen worlds. Growing in shadowed places and unfurling slowly, it has long been associated with magic, invisibility, and the idea that not everything valuable is immediately visible.

Below, we’ll explore the deeper meaning of the fern, and why this subtle, often overlooked plant has held such powerful symbolism across history.

This is part of my Celtic Tree Calendar art project which I did over 2020-2021 - you can find out about the Celtic Tree Calendar here and see my project here...

I’ve always felt there’s something quietly magical about ferns - the way they appear in shaded places, unfolding slowly, as if revealing something just out of reach.

In Celtic times, the fern was associated with the ‘ngetal’ ogham letter - but there is actually some confusion over which plant or tree the ogham letter ‘ngetal’ actually refers to.

The Ogham Tract text, which dates from the 12th century, links fern to the ngetal ogham – but the earlier Scholars Primer links the ngetal ogham to broom.

Ngetal may also refer to reed, since the old Irish word for broom, ‘giolach’, also means reed. Occasionally it is thought to refer to dwarf elder.

It is likely that a specific plant was less important here than the use which the broom, reed, or fern could be put to, which uses were very similar, including thatching, fuel, bedding, compost or mulch.

So while the exact plant may be debated, the meaning of the fern in this context comes from shared qualities - usefulness, resilience, and a quiet, almost hidden presence in the landscape.

I chose fern as it's a lovely plant to draw and a really interesting plant in terms of folklore, symbolism and meaning...

The meaning of the fern centres around themes of hidden knowledge, protection, resilience, magic, and the unseen forces of nature.

Fern Symbolism, Myth & Meaning

Fern

The fern is one of our oldest surviving plants – ferns were around even before the dinosaurs and date from the Mesozoic era (at least 66 million years ago).

The most common British wild ferns are:

• Male fern (Dryopteris filix-mas)
• Bracken (Pteridium aquilinum)

But there are over 40 wild fern species including the Maidenhair fern and the Moonwort fern.

The fern was a useful plant for our ancestors and we can get some clues as to how they used the fern through the common names used (sometimes still today) for the various fern species…

For example, the Adder’s Tongue Fern has leaves that look like a snake’s tongue – this was used as a remedy for snake bite, as well as various tongue conditions. But it’s wise to take care… as carrying this fern may well actually attract adders to you!

The Adder’s Tongue fern was also used to heal swellings as an eye lotion – it’s called the ‘herb of 100 miracles’ by the French.

The Male fern was sometimes called ‘St John’s Hands’, ‘Lucky Hands’, or ‘Dead-man’s Hands’ – the fern roots were collected on St John’s Eve (23rd June) and trimmed so that they looked like a hand, with fingers and thumb, and then baked in the oven. People would carry this ‘Hand of St John’ for protection at night.

The ‘Moonwort’ (Botrychium lunaria) was named for its half-moon shaped leaves – but it was also known as ‘Unshoo-the-horse’ due to its believed remarkable ability to work on metals. People thought that the moonwort fern could remove the nails from the horseshoes of any horses which stepped on it…

It is said that 30 of the Earl of Essex’s best horses all lost their horseshoes after stepping on moonwort while crossing White Down, Tiverton.

The moonwort’s abilities were so powerful that it was thought that moonwort gathered by moonlight could open locks, loosen hinges and turn quicksilver into pure silver – an impressive trick!

Fern

The Magical Fern

Ferns were believed to be highly magical. The fern’s most exciting magical property was the ability to make the wearer or carrier invisible!

The fern seeds were so tiny that people thought that the seeds were actually invisible – and so if you wore fern seed you would be able to become invisible too.

This was quite a commonly held belief – Shakespeare writes (in Henry VI) “We have the receipt of fern seed – we walk invisible.”

In the late 19th century, we also hear tell of a Scottish gentleman who recorded that his family were unable to see him after he’d crossed a ferny meadow!

This idea of invisibility speaks to something deeper in the meaning of the fern - the idea of hidden knowledge, unseen protection, and quiet power that isn’t immediately visible.

People made quite some effort to gather fern seeds so that they could enjoy the undoubted benefits of invisibility. Those who would gather fern seed must do it on St John’s Eve (23rd June) at midnight. The fern seed (from bracken) must fall naturally from the plant without being shaken or touched…

A quantity of pewter plates was advised, too – 11 to be precise. It was said that the fern seed would slip through the first 10 plates but finally be caught by the 11th.

The fern becomes a symbol of things just beyond our grasp - knowledge, power, or transformation that must be sought carefully and respectfully.

Ferns

In Ireland, it’s said that one man was beaten all over by fairies as he attempted to gather fern seed in a box – all the while the fairies whispering their evils in his ears. By the time he’d reached home with his box of hard-won fern seeds, they’d all vanished!

Fern seed scattered amongst a store of money was said to ensure the wealth would never diminish.

The fern was believed to be a very powerful magical plant. In the 14th century Welsh legend of Taliesin ‘The Battle of the Trees’ (Cad Goddeu), fern is used to discover the god of the enemy, and thus their underlying power.

Fern has been known as the ‘death flower’ and ‘treasure fist’ because they were seen to grow on ancient burial mounds and there were guarded by the trolls within who kept the treasure there safe. The fern was said to signify the presence of such buried treasure.

The Male fern was considered as an aphrodisiac and the root was used in love potions – but it was also used as a steam inhalation to clear congestion in the head. It was also used to clear tapeworms – and even in World War Two, children were encouraged to gather the fern roots for this medicinal quality as a useful home remedy.

Ferns

Bracken was known as the ‘Fern-of-God’ in Ireland and it was believed that if you cut through the stem you could read the initials of Jesus Christ (J.C.) or if you cut the stem into three parts, you may see G.O.D.

Perhaps you might just be lucky enough to read the initials of your future spouse in the bracken stem or see the image of an oak tree – maybe even with King Charles hiding inside it!

Taking a bite of the first bracken fern of Spring was believed to help you avoid toothache all year!

Or it’s just possible that fern could confer perpetual youth on you!

And fern tied to a horse’s ears could keep the devil away and confound witches so they couldn’t harm the horse.

But do take care if you’re considering uprooting a fern – pulling up a fern could cause a storm or may affect you to lose your wits!

Burning bracken could also affect the weather and was thought to bring rain! It was widely believed that, “the burning of ferne doth draw down rain.”

This reinforces the fern’s reputation as a plant that sits on the boundary - between safety and danger, the known and the unknown.

Ferns

But if you burned fern leaves on 30th July, the feast day of St Abdon, the patron saint of cleanliness, and then scattered the remnants around the house, it could keep away insects – and any other unwanted guests!

It was said that you would lose your way and be followed by snakes if you wore fern…

But if you were a woman and were able to slip a fern into your beloved’s shoe, you would know he was yours forever (at least until he became lost to the wandering snakes!)

It was said that the Maidenhair fern (when mixed with bear grease, laudanum, lamp-black, and soot) would prevent baldness (so said Pliny).

And the small fern known as ‘wall rue’ (Asplenium ruta-muraria) was believed to keep witches away – but also was used as a remedy for rickets (‘the taint’) so giving it its other common name of ‘tentwort’.

The Healing Fern

The meaning of the fern often centres around hidden knowledge and quiet resilience...

Ferns have been used medicinally since ancient times. As well as the previously mentioned remedies –

• Maidenhair fern has been used for colds and as a cough syrup

• Dog fern could be used with shamrock and butter as an ointment to ease back ache

• Male fern was used as a cattle and sheep medicine for a condition called ‘fluke’ (in addition to being used for congestion and worms in humans)

• Ferns have a traditional use for constipation

Even here, the fern reflects its deeper symbolism - a plant of quiet support, working subtly rather than dramatically.

Today, fern is considered toxic and should never be self-administered for any condition.

Meaning of the Fern

When we look at the meaning of the fern, we find a plant deeply connected to mystery, protection, and hidden strength.

Fern is a plant of the unseen - associated with invisibility, magic, and knowledge that lies just beyond ordinary perception.

It represents resilience and quiet endurance, thriving in shaded places and continuing to grow where other plants might struggle.

At the same time, fern is practical and grounding - a plant used for warmth, shelter, and everyday life, connecting the magical with the ordinary.

Fern symbolism reminds us that not everything powerful is obvious - and that some of the greatest strength lies in what is hidden, patient, and quietly persistent.
