Synonym(s): Polystichum falcatum (L. f.) Diels
Family: Dryopteridaceae (Wood Fern Family)
Duration and Habit: Perennial Fern
Japanese holly fern is an upright fern that forms a rounded mound up to 2 ft (60 cm) high and 3 ft (1 m) wide. It sports glossy, very dark green fronds on slender, arching stems. The individual pinnae are leathery, serrated with sharp points, and have a remarkable resemblance to holly leaves - thus the common name. Spores, light green when young and dark at maturity, adhere to the backs of specialized fronds. Japanese holly fern is evergreen in frostfree areas, but loses its fronds in colder climates (Floridata - http://www.floridata.com/ref/C/cyrt_fal.cfm)
