Athyrium filix-femina

Prefers moist, well-drained, acid soils in full to partial shade. Tolerant of full sun if adequate moisture is provided. Protect from harsh winds, but provide adequate air circulation. Propagate by clump division every few years in the spring or by spore. Best used in the woodland garden or as an edge or border in the shaded garden.

Handsome crowns of feathery fronds are typical of this genus. Athyrium filix-femina, or lady fern, is an erect, fine filigreed foliage fern with dark red stems at maturity that grows 1-3’ tall and spreads to 2 ½’ wide. Tough and easy to grow, this beauty is the right choice for perennial borders and woodlands alike. A breathtaking flush of new fronds appears in the spring, with new leaves appearing throughout the season for a continuously fresh look.

Lady fern flourishes in bright shade and moist, rich, organic soil. Athyrium filix-femina is circumglobal and can be found in rich moist woods, thickets, fields, meadows, and ravines throughout North America. While it does tolerate wet feet, it does not tolerate clay. Athyrium tolerates sun if kept cool and consistently moist. To maintain verdant appearance, protect from harsh winds, but provide adequate air circulation. To propagate, divide lady fern clumps every few years in the spring. Unlike other ferns, lady fern is relatively tolerant of sun and dry soil as compared to many other ferns. They spread nicely but don't run.

In our shade garden, it partners well with bold leafed foliage like Hosta and Packera and is a great contrast with purple-hued plants like Heuchera ‘Palace Purple’. Like most ferns, Athyriums are deer resistant. It is a very low maintenance plant that adds a lot of aesthetic value to the landscape.
