Scientific name: Onoclea sensibilia
Its sterile fronds, which wither early, are light to brown-mottled green and deeply cut into long lobes which almost reach the stem.
It can grow in very wet soils as long as there is adequate oxygen. It cannot tolerate sour clay or stagnant water. Also, does not tolerate freezing well, turning black even in light frost.
Twice-pinnate fertile fronds appear in late summer and, though dead, remain upright through winter. Fiddleheads appear in the spring in shades of pale red.
