I’m not much for common plant names, too many and too imprecise, but I do like the name “fairy wings” instead of the pedestrian “barrenwort” to refer to Epimedium. I first encountered the common name “fairy wings” applied to Epimedium in Plant Delights Nursery catalogue, a rebranding, which perfectly describes the delicate, ethereal flowers that resemble tiny butterflies or fairies about to take flight in the garden. As an Epimedium enthusiast, I have no problem rebranding myself a fairy wings freak.
Epimedium alpinum
In 1753 Linnaeus named and described one European Epimedium species, Epimedium alpinum. In the centuries since Linnaeus published Species Plantarum, 50 species of Epimedium have been described, including 15 Chinese species of fairy wings introduced as recently as 1989.

So, although Epimedium got off to a slow start in the 18th century ornamental market, by 1821 a few more Epimedium species had been described, including Epimedium pinnatum from Iran and Epimedium pubigerum from Turkey

But it was Dr. Von Siebold’s collections of the Japanese species: Epimedium grandiflorum and Epimedium diphyllum in 1830 that changed the marketing of Epimedium in the West. When the Japanese species bloomed in the University of Ghent Botanic Garden, botanists and illustrators took notice. The new Epimedium plants were introduced in 1835 and distributed to public gardens and commercial nurseries in Europe and Britain. Meanwhile, Belgian botanists at Ghent began hybridizing.

Today there are hundreds of cultivars of E. grandiflorum, including the excellent ‘Lilafee,’ which resembles the 1860 illustration Epimediuim grandiflorum var. violaceum, just as the white cultivars resemble the 1839 illustration of Siebold’s collection of E. grandiflorum. The Belgians also hybridized all available Epimedium species to produce the garden hybrids in cultivation.

William Stearn, the English botanical scholar and naturalist, who wrote the first comprehensive monograph on The Genus Epimedium credits the great English plantsman Reginald Farrer’s 1919 encyclopedia The English Rock Garden for his introduction to the genus Epimedium. Stearn devoted himself to sorting through the tangle of Epimedium garden hybrids and did his best to keep up with the introduction of new species as they trickled into herbaria through the 20th century. He finally completed his comprehensive work on Epimedium in 2003.

What does the x mean? Epimedium x perralchicum is a hybrid between two species: (E. perralderianum x E. pinnatum subsp. colchicum). ‘Frohnleiten‘ is a German selection of Epimedium x perralchicum. The selection is known as a cultivar. ‘Frohnleiten‘ produces clear yellow flowers similar to E. pinnatum subsp. colchicum, but it is the evergreen foliage that puts on the show. Young leaves emerge bronzed in spring, turn lustrous green in summer, and bronze again in autumn.

Japanese botanist Mikinori Ogisu introduced 15 new Epimedium species into cultivation in 1989, and more recent discoveries bring the total to 52 species of fairy wings, most native to China, as well as an increasing list of garden hybrids like E. x ‘Asiatic Hybrid’ (below). Stearn warned that the excessive introduction of garden hybrids, especially from Japan, is “much to be deplored if it leads to the neglect and loss of original species.”

Epimedium x ‘Asiatic Hybrid’ is one of many fairy wings hybrids introduced in the 1990s, probably the result of a cross between Epimedium acuminatum and an unidentified parent: blooming in Laura’s garden 28 April 2014

My fairy wings collection includes 12 species and garden hybrids. I’m particularly smitten with Epimedium acuminatum, its purple flowers the largest of any of the fairy wings.

Fairy wings make excellent ground covers for shady gardens and integrate well with shady companions, including Helleborus, Arisaema (Jacks), Brunnera (perennial forget-me-not), Asarum and Saruma (ornamental ginger), Podophyllum (May apple), Jeffersonia, and other wildflowers.

Plant Delights, my favorite mail order perennial plant nursery is noted for its bizarre catalogue covers and memorable Hosta introductions—‘Elvis lives,’ ‘Dixie Chick,’ Green Jeans,’ ‘Red Neck Heaven,’ ‘Squash Casserole,’ ‘Swamp Thing,’ ‘Surfer Dude,’ and ‘White Wall Tire.’ Plantsman-owner Tony Avent offers more than three dozen fairy wings selections, including his 2013 introduction, Epimedium ‘Splish Splash,’ with mottled foliage and white flowers, which he describes as “quite a show with or without the flowers.”
