Dryopteris affinis
Golden Male Fern, Golden Shield Fern, Scaly Male Fern, Golden-Scaled Male Fern
A large, architectural fern native to the cool, damp woodlands of western Europe — from the Atlantic coasts of Ireland and Portugal across to the Caucasus and Macaronesia. It forms a bold, upright shuttlecock of lance-shaped, once-divided fronds that can reach 90–120 cm in height, making it one of the most striking hardy ferns for a temperate setting. Its defining feature is the dense covering of golden-brown scales on the frond midribs, which give the plant its common name and catch the light as new fronds unfurl in spring a flush of bronze. At that scale it is too large for a standard terrarium, but it suits large open paludariums and cool woodland vivaria that replicate its natural habitat.

Care
Prefers high humidity, indirect light, with -15–24 °C, and reaches 120 cm at maturity.
