Bracken, Pteridium esculentum, is one of the oldest and most successful ferns, with fossils over 55 million years old. The word Bracken is of Old Norse origin, related to the Swedish word bräken, meaning fern. The plant sends up large, triangular fronds from a wide-creeping underground rootstock, and may form dense thickets. This rootstock may travel a metre or more underground between fronds. Bracken fiddleheads (the tightly curled young fronds) are edible but must be cooked.

Compounds from Bracken can leach into water supplies, causing an increase in the incidence of gastric and oesophageal cancers. Bracken fiddleheads or rhizomes are prepared by roasting in hot ashes, then either eaten fresh or preserved by salting, pickling, or sun drying.
