Asplenium scolopendrium, commonly called hart’s tongue fern, is a rhizomatous, evergreen fern that typically produces an erect-arching clump of tongue-shaped, leathery, bright green fronds (12-18” long) which may have wavy margins. Sori are arranged on the frond undersides in rows. Primarily native to Europe, although there exists a rare American variety (Asplenium scolopendrium var. americanum) that reportedly may be found in a very limited number of sites in Alabama, Tennessee, Michigan, New York and Ontario. The American variety is currently classified as threatened in its entire range. Plants sold in commerce are the European variety. Synonymous with Phyllitis scolopendrium.
