Fern (Athyrium)

Athyrium is a genus of mostly deciduous ferns with graceful, feathery fronds. Species and cultivars vary widely in size and foliage color, so this genus-level record describes the shared shade-garden character rather than one particular lady fern. ## Foliage and Garden Use The Royal Horticultural Society describes Athyrium fronds as finely divided and lace-like, emerging from a central crown in spring; cultivars range from low ground-huggers to forms around 1.2 m tall. North Carolina State Extension describes the genus as occurring mostly in moist woodland settings and notes that frond colors can include green, reddish and silver tones. These ferns add soft texture to woodland borders and shaded plantings.

Protect delicate foliage from hot sun and drying winds, and keep soil evenly moist through summer without leaving it waterlogged. Some species tolerate drier conditions better than others, so check the species or cultivar when available. [RHS growing guidance](https://www.rhs.org.uk/plants/athyrium/growing-guide) · [NC State Extension](https://plants.ces.ncsu.edu/plants/athyrium/) ## Maintenance Remove old fronds as fresh growth emerges in spring and water during dry spells. Mulch with organic matter to conserve soil moisture. Divide established clumps or propagate from spores when a particular species’ requirements are known; genus members differ in mature size and hardiness.
