Hardy Maidenhair Fern

Adiantum × mairisii (ad-ee-AN-tum mair-IS-ee-eye)

Family: ‎Pteridaceae Unknown Herbaceous (1-3 ft)

Mairis's Maidenhair is a sterile, artificial hybrid between Adiantum capillus-veneris and a tropical maidenhair, either A. raddianum or A. aethiopicum in the Ribbon-fern family (Pteridaceae). It grows in partial, dappled, or deep shade and in organic, loamy, or sandy soil. The fern likes moisture and good drainage. It grows about 1 to 1.5 feet high by 1.5 to 3 feet wide in a mounding form. It has bright green, lacy fronds that provide year-round interest. It is hardier than either parent. This perennial fern works well in a woodland or shade garden, or even in containers. Diseases, Insect Pests, and Other Plant Problems: No significant diseases or pests. The Florida Fern Caterpillar can be a problem. VIDEO Created by NC State Extension's Homegrown series featuring Mark Weathington , Director of JC Raulston Arboretum . More information on Adiantum .
