Noteworthy Characteristics 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. Common name is in reference to the supposed resemblance of the frond shape to a deer’s tongue. Sori are arranged on the frond undersides in rows that purportedly resemble the many legs of a centipede (skolopenda meaning centipede in Greek). 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.
