Athyrium filix-femina, commonly called lady fern, is a deciduous fern that features lacy-cut, erect or ascending, 2 to 3-pinnate or pinnatifid, finely-divided, lanceolate, light green fronds which grow in a dense circular shuttlecock-like clump to 2-3' tall. Each frond (leaf) has twenty to thirty pairs of elliptic non-opposite pinna (leaflets) with narrow pointed tips. Each pinna is divided into deeply-cut lanceolate to oblong pinnules (subleaflets). Sori and indusia are found on the undersides of the pinnules. This is a circumglobal species which is found in rich moist woods, thickets, fields, meadows and ravines throughout northern North America, Europe and Asia.
Easily grown in rich, medium moisture, well-drained soil in part shade to full shade. Tolerates drier soils than many other ferns. Will tolerate full sun, however, only if soil is kept constantly moist. Shelter from wind to protect fronds from breaking. Divide clumps in spring every few years to reposition crowns at the soil level.
