Dryopteris filix-mas, the male fern, is one of the great woodland ferns of the Northern Hemisphere, a large, fine-textured plant found wild across Europe, Asia, and North America and grown in gardens for centuries. The species name means literally the male fern, an old contrast with the more delicate lady fern. The selection 'Undulata Robusta' is a robust, vigorous form with gently undulate, wavy frond margins that catch the light along the edge of each leaf.
Deciduous to semi-evergreen, the robust male fern wants cool, moist, shaded ground rich in leaf mould, where the arching fronds build a substantial clump in a season or two. Easy, long-lived, and deer-resistant, the male fern is a plant for the difficult shade beneath trees. Woodlanders carried 'Undulata Robusta' among the many Dryopteris selections in a broad fern collection.
