Cyrtomium falcatum is a species of fern known by the common names house holly-fern and Japanese holly fern. It is native to eastern Asia. It grows from crevices in coastal cliffs, stream banks, rocky slopes, and other moist, stable areas.
Cyrtomium falcatum, commonly called Japanese holly fern, is native to eastern Asia, India, southern Africa and Hawaii. The fronds of this fern resemble holly branches. This is an evergreen fern (deciduous in St. Louis) that typically grows in a dense, vase-shaped clump to 2’ tall. Arching, glossy, dark green fronds (1-2.5’ long) are noted for their thick, leathery pinnae, which are falcate (sickle-shaped) as the species name suggests. Spores are easily carried by wind, and species plants have escaped gardens and naturalized in certain areas of the southeastern U.S.
