Matteuccia struthiopteris

Matteuccia struthiopteris (common names ostrich fern, fiddlehead ferns or shuttlecock fern) is a crown-forming, colony-forming fern, occurring in temperate regions of the Northern Hemisphere in eastern and northern Europe, northern Asia and northern North America. The species epithet struthiopteris comes from Ancient Greek words, struthio meaning ostrich and pteron meaning wing.

Ostrich Fern Foliage
It grows from a completely vertical crown, favoring riverbanks and sandbars, but sends out lateral stolons to form new crowns. It thus can form dense colonies resistant to destruction by floodwaters.
The fronds are dimorphic, with the deciduous green sterile fronds being almost vertical, 100–170 cm (39–67 in) tall and 20–35 cm (7.9–13.8 in) broad, long-tapering to the base but short-tapering to the tip, so that they resemble ostrich plumes, hence the name. The fertile fronds are shorter, 40–60 cm (16–24 in) long, brown when ripe, with highly modified and constricted leaf tissue curled over the sporangia; they develop in autumn, persist erect over the winter and release the spores in early spring.

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 these ferns are 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 not considered advisable to eat uncooked fiddleheads because illness has been traced to that practise.
