Bracken ( Pteridium) is a genus of large, coarse ferns in the family Dennstaedtiaceae. Ferns (Pteridophyta) are vascular plants that have alternating generations, large plants that produce spores and small plants that produce sex cells (eggs and sperm). Brackens are noted for their large, highly divided leaves.
bracken, (Pteridium aquilinum), widely distributed fern (family Dennstaedtiaceae), found throughout the world in temperate and tropical regions. The fronds are used as thatching for houses and as fodder and are cooked as vegetables or in soups in some parts of Asia.

Pteridium esculentum, commonly known as bracken fern, Austral bracken or simply bracken, is a species of the bracken genus native to a number of countries in the Southern Hemisphere. Esculentum means edible.
Bracken is thought to be the most common plant in the world and is found on all continents except Antarctica. In the UK, they thrive in woodland. 1/5. Butterflies live in habitats dominated by bracken and can be seen flying over the tops of the plant from April to mid-August.
Bracken is the UK's most common fern and grows in dense stands on heathland, moorland, hillsides and in woodland. It is a large fern that favours dry, acid soils and spreads by underground rhizomes. Unlike many ferns, bracken dies back in winter, leaving brown, withered fronds that pepper the landscape.
It is a herbaceous perennial, with fronds dying back in autumn and new growth appearing in spring. Bracken spreads by rhizomes (underground stems) and windborne spores. If you need to control bracken, non-chemical methods are effective, but it can take time to get rid of completely.
Global distribution. Bracken is one of the most widely-distributed plants in the world, and occurs on every continent except Antarctica, as well as isolated oceanic islands such as Hawaii.
Hardy and vigorous, Pteridium aquilinum (Bracken Fern) is a deciduous, rhizomatous fern with large triangular fronds, up to 3 ft. long (90 cm), arising directly from a deep underground rhizome. Each frond is 2-3 times pinnately compound.
