Pteridomania: The Fern Craze That Took Victorian Britain by Storm
In the mid-19th century, Britain was gripped by an unlikely obsession. Forget royal scandals or political drama—this cultural phenomenon had its roots, quite literally, in the forest floor.
It was called Pteridomania, or “fern craze,” and for several decades, it left no corner of Victorian life untouched. Ferns appeared in drawing rooms, on tea sets, in wallpaper patterns, and even on gravestones. They were pressed into albums, embroidered onto dresses, and grown obsessively in glass terrariums.
But this wasn’t just a design trend. Behind the elegant fronds was a movement that blended science, exploration, class aspiration, and even quiet rebellion—especially by women excluded from academic spaces.
🌿 Where It All Began: Pteridomania Takes Root
The fern craze began in the 1850s, fueled by a potent mix of scientific enthusiasm, rising literacy, increased leisure time, and a booming publishing industry. This was a time when amateur science became a fashionable pastime for the growing Victorian middle class, and few hobbies were considered as refined—or as thrilling—as the study of plants.
Botany offered the perfect combination of outdoor activity, domestic display, and intellectual cachet. It was especially appealing because it could be pursued at home or in the field, by women as well as men, and by urban dwellers as easily as those in the countryside. And among all the plants available for study, ferns captured the imagination like no other.
With their prehistoric origins, symmetrical fronds, and silent, mysterious reproduction (no flowers, no seeds!), ferns were seen as elegant and slightly otherworldly. They were ancient yet modern, wild yet decorative. And they were everywhere, especially in the North, now easier to reach thanks to the development of new and better roads.
In 1855, Charles Kingsley, the novelist and clergyman best known for The Water-Babies, gave this growing phenomenon its name: Pteridomania, or “fern madness.” Writing with a mixture of amusement and admiration, Kingsley described how:
Your daughters, perhaps, have been seized with the prevailing ‘Pteridomania‘ … and wrangling over unpronounceable names of species (which seem different in each new Fern-book that they buy) … and yet you cannot deny that they find enjoyment in it, and are more active, more cheerful, more self-forgetful over it, than they would have been over novels and gossip, crochet and Berlin-wool.
But his gentle satire didn’t slow the trend. If anything, it made it more appealing.
A Publishing Boom
The rise of fern mania coincided with an explosion in publishing. Between the 1840s and 1870s, dozens of fern-focused books were published, from field guides and collectors’ manuals to illustrated botanical folios. Many were written in accessible language, often aimed at “ladies and amateurs.” Some of the most popular included:
- The Ferns of Great Britain and Ireland (1855), featuring detailed illustrations by Lady Charlotte Mary Cox and printed using the nature-printing technique (literally pressing the plant onto a plate).
- The Book of British Ferns by Charles T. Druery, a guide that became a household staple among collectors.
- Ferns: British and Exotic by Edward Newman, which combined scientific detail with practical advice on fern cultivation.
These books were often lavishly illustrated, sometimes hand-colored, and were treasured not only as reference works but as decorative objects. They played a central role in turning fern collecting into a national pastime—and made botanical terminology part of everyday vocabulary in many Victorian households.

Botanical Fever for the Masses
The appeal of ferns wasn’t just scientific—it was also deeply tied to the Victorian love of classification and order. Ferns came in a bewildering number of varieties, from delicate maidenhairs to sturdy hart’s tongues. Their spores were invisible to the naked eye, adding an air of mystery to their reproduction. For Victorians obsessed with cataloguing the natural world, this was irresistible.
At the same time, ferns were eminently collectible. They could be pressed, sketched, grown in glass cases, embroidered, or arranged in decorative scrapbooks. Their popularity crossed class boundaries—from aristocratic collectors to working-class gardeners—and they were as likely to be found in suburban parlors as in scientific institutions.

A Cross-Class Obsession
One of the most remarkable features of Pteridomania was its reach. Unlike many Victorian hobbies that were confined to a single social group, the fern craze transcended class boundaries in both practice and style.
The aristocracy, with their sprawling estates and glass conservatories, imported exotic species from colonial expeditions and commissioned elaborate fern houses—specially built structures designed to replicate tropical conditions. These private collections became markers of taste, education, and imperial reach.
The middle class, eager to emulate elite refinement, turned to more accessible methods. They filled Wardian cases—small tabletop terrariums originally invented to transport plants across oceans—with locally sourced ferns and moss. These miniature greenhouses were perfect for displaying ferns in drawing rooms, where they doubled as science and decor.
Meanwhile, the working class found their own ways to participate. Thanks to mass production, fern motifs appeared on inexpensive ceramics, wallpapers, pressed glass, and textiles. You didn’t need to own a real fern to be part of the trend—you could wear them, drink tea from them, or hang them on your wall.
Fern Hunting: Romance, Risk, and Rivalry
For many Victorians, fern collecting wasn’t confined to the home—it was an excuse to get outside. Fern hunting became a legitimate weekend activity, especially for city dwellers newly connected to the countryside by expanding railways. Entire families would take trains to fern-rich regions, armed with field guides, collecting tins, and a picnic lunch.
And for young people, it offered something else: a socially sanctioned way to be alone together. As strange as it sounds now, fern hunting was considered an ideal courtship activity. With just enough structure to appear respectable and just enough wilderness to offer freedom, it allowed couples to share time, conversation, and discovery away from the eyes of chaperones.
But this pastoral image masks a darker side. As demand for rare ferns grew, competition became fierce. Collectors scaled cliffs, trespassed on private land, and raided protected glens to secure coveted specimens. Some went so far as to publish false location guides to throw off rivals.
The Killarney Fern (Trichomanes speciosum), with its delicate fronds and ghostlike appearance, became the most sought-after prize. Native to damp, shaded areas of Ireland and western Britain, it was nearly wiped out by overharvesting. Today, it is one of the few plants protected under European conservation law—and serves as a cautionary tale about the ecological impact of trend-driven collecting.
Women at the Forefront
While much of the Victorian scientific world remained closed to women, Pteridomania quietly opened a side door.
Fern collecting was one of the few intellectual hobbies that women could pursue respectably—and visibly. It required close observation, careful documentation, and knowledge of classification systems, all of which aligned with the broader scientific values of the time. But unlike formal science, it could be practiced at home, in the garden, or on countryside excursions—making it socially acceptable for women across classes.
Some women became highly skilled collectors and cultivators, creating private collections that rivaled those of their male contemporaries. Others took up botanical illustration, often collaborating with family members or publishers. Their detailed drawings were used in field guides, scientific journals, and collector’s manuals—though more often than not, their names were omitted or replaced by those of male editors, fathers, or husbands.
Among those who left a more visible mark, Lady Charlotte Mary Cox contributed nature-printed fern illustrations to The Ferns of Great Britain and Ireland, a landmark publication from the fern craze’s peak. Meanwhile, women like Marianne North, Anna Atkins, and Elizabeth Twining—featured in my post on female botanists and botanical illustrators—used their artistic and scientific skills to document plant life on a much larger scale, transcending the trend while also benefiting from the cultural space it created.
In this way, Pteridomania wasn’t just about ferns—it became a subtle entry point for women into the worlds of taxonomy, fieldwork, scientific publishing, and visual education.
Some, like Atkins, would go on to pioneer photographic documentation. Others, like Twining, focused on public education and accessibility. What united them was the ability to use public enthusiasm—even when it was fleeting or decorative—to advance lasting contributions to science and knowledge.
A Global Trade Rooted in Empire
As Britain expanded its reach across the globe, new plant species were brought back from colonies in India, Australia, the Caribbean, and the Americas. These plants traveled thousands of miles thanks to a key invention: the Wardian case. This sealed glass box created a stable environment that allowed live ferns to survive long sea journeys. It changed the way plants moved—and who had access to them.
In many cases, the ferns that ended up in British greenhouses had been taken from remote rainforests or mountain valleys. They were collected by plant hunters—some working for botanical institutions, others for private collectors—who relied on colonial networks to find and transport rare specimens.
Back in Britain, these “exotic” ferns became symbols of taste and refinement. But they also raised important questions: Who did these plants really belong to? What was lost when they were removed from their native ecosystems? And how did a decorative trend in one country affect landscapes in another?
Pteridomania may seem like a charming footnote in history, but it reflected much deeper issues around access to nature, environmental impact, and the power structures behind collecting.

A Lasting Impression
y the end of the 19th century, the fern craze began to fade. New scientific discoveries, changing tastes, and shifting social priorities made way for other botanical interests and garden trends. But the imprint of Pteridomania didn’t disappear—it lingered in Victorian architecture, domestic design, and the enduring presence of ferns in homes and gardens today.
More than just a curious chapter in plant history, the fern craze reveals how science, aesthetics, class, gender, and even empire have always been closely connected—sometimes in subtle, decorative forms that seem innocent at first glance.
