Adiantum pedatum



One of the most vigorous species, from the eastern side of the USA. Should do well here in light shade with constant moisture (currently the falling rain is flowing in a sheet down the road outside - I can do moisture).

Sue Olsen says:

"This North American native is found in moist deciduous woods from midwestern regions to the Atlantic Coast. Not surprisingly, alert British colonists, recognising a good thing, sent plants home. It was one of the first North American fern exports, although not so profitable as those "funny" leaves (tobacco) exported from Virginia."

Plant Delights Nursery say:

"Without a doubt, the widespread Adiantum pedatum (Canada south to Florida) is one of our most elegant North American native ferns. The horizontal horseshoe-like wreath of foliage rests atop 18-24" tall, wiry black stems. Northern maidenhair fern thrives in moist, rich soil, but also grows well in all but the driest of woodland garden sites. The light, airy, fine texture of the fronds serves as a perfect backdrop for hostas and other bold foliage plants. In early April, this deciduous native fern unfurls for a true Kodak moment. In 10 years, expect a 2' wide deer-resistant clump. In the 1900s, it was used medicinally to treat arthritis, asthma, nasal congestion, wound bleeding, and to cleanse and condition shiny hair...better plant several clumps.
Northern maidenhair fern prefers a cool, moist soil, but thrives in hot, humid climates as long as the soil doesn't stay dry for extended periods. This North American native often occurs naturally on calcium-rich soils, although they also perform well in woodland garden conditions on slightly acidic soils. They prefer light, open shade and do not thrive well in either part of full sun conditions."
