Pteridium aquilinum
Bracken
Polypodiaceae
Ferns
Usually colonizing open forest or disturbed areas, bracken has big, triangular fronds that rise on 2–7-ft. stalks. Found all overthe world, its subspecies differin minor details; P. a. pubescens is native to the West. Its coarse, much-divided fronds rise directlyfrom deep, running rootstocks.
Bracken is fine in untamed locations, but keep it out of the garden, where deep rootstocks make it a tough, invasive weed. Fiddleheads are carcinogenic.
