Phegopteris–commonly called beech fern–is a genus of deciduous terrestrial ferns that are found in damp soil on shady banks and rocks in areas of high rainfall in the Northern Hemisphere. Phegopteris are cultivated in gardens in deep shady areas with damp soil.
The genus Phegopteris is synonymous with the genus Thelypteris. Thelypteris is one of the largest genera of ferns, comprising nearly a thousand species native to tropical and subtropical wet forests. A few species are found in temperate regions, including the three species of Phegopteris listed below.
Phegopteris have pinnate-pinnatifid blades that bear minute, needle-sharp hairs; fronds are 1 to 2 feet tall.
