Leatherleaf Fern (Rumohra adiantiformis): Glossy, Durable Fern for Floral Design and Gardens

Overview

Leatherleaf fern (Rumohra adiantiformis), also called leathery shield fern, is a tough, evergreen fern native to southern Africa, South America, and Pacific islands. Its glossy, dark green, tripinnate fronds—12–24 inches long—have a distinctly leathery texture and serrated margins. The fronds are exceptionally long-lasting when cut, making this fern a staple of the floral industry worldwide. In gardens, it forms a dense, arching clump 2–3 feet tall and wide.
