Intermediate Wood Fern

Dryopteris intermedia

Also known as Evergreen Wood Fern, Fancy Fern, Glandular Wood Fern, American Shield Fern

Intermediate wood ferns unfurl intricately divided, lacy fronds that remain vibrant green beneath heavy snow blankets throughout winter. Minute glandular hairs coat the central stalk and leaflet veins, giving the foliage a slightly textured, aromatic character when brushed. Anchoring moist forest slopes across eastern North America, this resilient perennial plays a key ecological role in understory soil stabilization and serves as a vital ancestral parent to several widespread hybrid ferns.
