A native of tropical and temperate regions in the United States, Central and South America, Eurasia, western Asia and Australasia this deciduous fern is widely grown in the garden and as a houseplant for its delicate foliage. The bi-pinnate and tri-pinnate fronds have bright green, fan-shaped pinnae and wiry black stems that arch gracefully downward. Sori (clusters of spore cases) appear in summer on the undermargins of the pinnae. The plant is clump forming and has a creeping rhizome. It may go dormant in summer if water is lacking. The genus name, Adiantum, comes from the Greek work meaning unwettable and refers to the fact that the fronds shed water. The specific epithet, capillus-veneris, means “hair of Venus” hence the alternative common name, Venus hair fern. This fern is a good choice for a shade garden and is especially attractive growing in moist crevices. The foliage is highly deer resistant.
