Classification

''Matteuccia struthiopteris'' is the only species in the genus ''Matteuccia''. Some sources include two Asian species, ''M. orientalis'' and ''M. intermedia'', but molecular data shows that ''M. struthiopteris'' is more closely related to '' Onocleopsis'' and '' Onoclea'' (sensitive fern) than it is to ''M. orientalis'' and ''M. intermedia'', and so the latter should be moved to a genus '' Pentarhizidium'' which contains those two species. Formerly classified as a member of the

Distribution

It is a crown-forming, colony-forming plant, occurring in temperate regions of the Northern Hemisphere in central and northern Europe, northern Asia, and northern North America. It grows from a completely vertical crown, favoring riverbanks and sandbars, but sends out lateral

. While choosing a place of planting it should be taken into account that this fern is very expansive and its leaves often lose their beauty throughout the summer, especially if not protected from wind and hail. The tightly wound immature fronds, called fiddleheads, are also used as a cooked vegetable, and are considered a delicacy mainly in rural areas of northeastern North America. It is considered inadvisable to eat uncooked fiddleheads. Brown "scales" are inedible and should be scraped or rinsed off. The sprouts are also picked all over Japan, ("kogomi" in Japanese) as well as in other Asian regions, where they are considered a delicacy. Additionally, in Norway, fiddleheads were apparently used in the manufacture of beer, and in Russia, in the control of gut parasites. ''Matteuccia'' species are used as food plants by the

Its base hosts the mushroom '' Woldmaria filiformis'', which is uniquely linked with this species of fern.
