Lady Fern

Athyrium filix-femina

Also known as Common Lady-fern, Northern Lady Fern

Lady ferns unfurl delicate, bright green fronds each spring from stout, scaly rhizomes, forming graceful arches in damp woodland understories. Their twice-to-thrice pinnate leaves feature distinctive crescent-shaped spore clusters on the undersides, which shed dust-like spores carried by autumn breezes. These hardy perennials die back completely in winter before re-emerging in lush clusters as warm weather returns.
