Fiddleheads are the tightly coiled young fronds of ferns, harvested in spring and eaten as a vegetable. In North America, the term usually refers to ostrich fern fiddleheads, though it can also describe young fronds of other fern species. They are a seasonal wild food and a traditional ingredient in some Indigenous and regional cuisines.

Description

Fiddleheads are the young, tightly coiled fronds of ferns. Their spiral shape gives them the common name, which is likened to the scroll of a fiddle or violin.

Edible species

Although many ferns produce fiddleheads, not all are edible. In North America, the ostrich fern is the species most commonly harvested and sold, while other edible species may occur in some regions.

Harvesting and preparation

Fiddleheads are usually harvested in early spring when the shoots are still tightly curled and only a few inches tall. Sources recommend cooking them thoroughly before eating.

Nutrition and use

Fiddleheads are described as a nutritious spring vegetable and a good source of vitamins A and C, niacin, and riboflavin. They are commonly cooked as a seasonal side dish or foraged food.
