    Care: Shade in moist soil
    Native: all parts of No. America including Wisconsin

    Adiantum is from Greek adiantos, unwettable because its fronds repel water.
    Cherokee made a tea for flu, fever and rheumatism, and powdered parts for heart ailments, paralysis and asthma. Native Americans made a hair wash from the stems and applied a topical poultice of masticated fronds to a wound to arrest bleeding. 1st described by French botanist Cornu (1635). Introduced to France from Canada where it grew in “such quantities that the French send it from thence in package for other goods and the apothecaries at Paris use it for (another Adiantum) in all their compositions in which that is ordered.” Philip Miller (1768). Tradescant the Younger introduced this fern to garden cultivation when he sent it to England around 1638. English herbalist Nicholas Culpepper claimed it to be “a good remedy for coughs, asthmas, pleurisy, etc., and on account of it’s being a gentle diuretic also in jaundice, gravel and other impurities of the kidneys.” Father of the mixed perennial border, William Robinson, called this “elegant.” It “is unquestionably one of the most distinct and beautiful of the hardy ferns.” The Garden 1876.
