Athyrium filix-femina, the lady fern or common lady-fern, is a large, feathery species of fern native throughout most of the temperate Northern Hemisphere, where it is often abundant (one of the more common ferns) in damp, shady woodland environments and is often grown for decoration.

Athyrium filix-femina is cespitose (the fronds arising from a central point as a clump rather than along a rhizome). The deciduous fronds are light yellow-green, 20–90 centimetres (7.9–35.4 in) long and 5–25 cm (2.0–9.8 in) broad. Sori appear as dots on the underside of the frond, 1–6 per pinnule. They are covered by a prominently whitish to brown reniform (kidney-shaped) indusium. Fronds are very dissected, being 3-pinnate. The stipe may bear long, pale brown, papery scales at the base. The spores are yellow on A. angustum and dark brown on A. asplenioides. 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.

Some authorities consider these two varieties to be separate species, in which case Northern Lady Fern is referred to as Athyrium angustum and Southern Lady Fern is referred to as Athyrium asplenioides. Athyrium filix-femina (Lady Fern or Common Lady-fern) is a large, feathery species of fern native throughout most of the temperate Northern Hemisphere, where it is often abundant (one of the more common ferns) in damp, shady woodland environments and is often grown for decoration. The plant is caespitose (the fronds arising from a central point as a clump rather than along a rhizome). The fronds are light yellow-green, 20-90 centimeter long and 5-25 centimeter broad; they are deciduous. Sori appear as dots on the underside of the frond, 1-6 per pinnule. They are covered by a prominently whitish to brown reniform (kidney-shaped) indusium. Fronds are very dissected, being 3-pinnate. The stripe may bear long, pale brown, papery scales at the base.
