Easy careTerrestrial60–120 cm

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.

Distribution

Propagation

Divide established crowns in early spring before new fronds fully emerge. Lift the clump and separate sections with a sharp spade or knife, ensuring each division has healthy roots and at least one growing point. Replant at the same depth in moist, humus-rich soil and water in well. Recovery is generally quick — new fronds typically appear within a few weeks.
