Pteridium aquilinum
bracken
Britain's largest and most widespread native fern, with huge, finely divided leaves 1-2m tall and 1m across. Spreading by rhizomes, with roots up to a metre deep, it forms dense thickets, smothering most other vegetation, and can also spread by spores. Young shoots emerge curled at the tip and are known as croziers or fiddleheads, and in autumn the deciduous fronds turn a rich russet-brown

It provides valuable cover for wildlife and is the food plant of a number of moth caterpillars, but is poisonous to livestock and likely to be too dominant for most gardens.
