Dryopteris filix-mas 'Undulata Robusta': Robust Male Fern

Dryopteris filix-mas 'Undulata Robusta' is a distinguished, crested cultivar of the Male Fern. It forms a robust, vase-shaped clump of erect, bipinnate fronds with distinctly undulate (wavy) and crested pinnae margins, giving a ruffled, substantial texture. The fronds are a deep, glossy green. It is larger and more vigorous than the typical 'Undulata'.

Plant Profile

This Male Fern cultivar thrives in partial to full shade and moist, humus-rich, well-drained soil. It is very tough, drought-tolerant once established, and long-lived. The wavy, crested pinnae add wonderful texture and movement. Excellent as a specimen, in masses, or in the fern border. Deciduous to semi-evergreen; cut back old fronds in late winter. A classic, improved cultivar.
