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 ''

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

Cultivation and uses

Fiddlehead sprouts as food in Tokyo area march 9 2020

The ostrich fern is a popular ornamental plant in gardens. It has gained the Royal Horticultural Society's Award of Garden Merit. 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) where they are a delicacy. ''Matteuccia'' species are used as food plants by the
