. 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
