Fiddlehead fern

Fiddleheads or fiddlehead greens are the furled fronds of a young fern, harvested for use as a vegetable.

Left on the plant, each fiddlehead would unroll into a new frond (circinate vernation). As fiddleheads are harvested early in the season before the frond has opened and reached its full height, they are cut fairly close to the ground.

Fiddleheads have antioxidant activity, are a source of omega-3 and omega-6 fatty acids, and are high in iron and fibre. Certain varieties of fiddleheads have been shown to be carcinogenic. (See bracken poisoning)

The fiddlehead resembles the curled ornamentation (called a scroll) on the end of a stringed instrument, such as a violin. It is also called a crozier, after the curved staff used by bishops, which has its origins in the shepherd's crook.

The fiddleheads of certain ferns are eaten as a cooked leaf vegetable. The most popular of these are:

Fiddleheads' ornamental value makes them very expensive in the temperate regions where they are not abundant.

Available seasonally, fiddleheads are both foraged and commercially harvested in spring. When picking fiddleheads, it is recommended to take only half the tops per plant/cluster for sustainable harvest. Each plant produces several tops that turn into fronds; repeated over-picking will eventually kill the plant. Maintaining sustainable harvesting methods is important in the propagation of any non-farmed food species.

Fiddleheads have been part of traditional diets in much of Northern France since the beginning of the Middle Ages, across Asia, and also among Native Americans for centuries. They are also part of the diet in the Russian Far East where they are often picked in the wild in autumn, preserved in salt over winter, and then consumed in spring.
