Edible Ferns: No Fern is Useless

Not all ferns are useless. Some are edible, some have medicinal properties, and some are just ornamental, but not totally useless or purposeless.

Fiddleheads are harvested early in the season before the frond has opened and reached its full height. They have antioxidant activity, are a source of omega-3 and omega-6 fatty acids, and are high in iron and fiber; though certain varieties of fiddleheads have been shown to be carcinogenic.
