Japanese Holly Fern

Cyrtomium fortunei (sir-TOH-mee-um for-TOO-nee-eye)

Family: Polypodiaceae Non-native Herbaceous (1-3 ft)

Japanese holly fern is an evergreen, herbaceous perennial fern in the polypody family (Polypodiaceae). Its region of origin is Eastern Himalaya to Korea and Indo-China. The species epithet honors famed 19th-century Scottish plant hunter Robert Fortune, This fern grows in partial to deep shade and needs moist, humus-enriched soil. Too much sun can bleach the fronds. Good soil drainage is essential to prevent root rot. It has been weedy in some areas of the South, so be careful about letting it naturalize. It can grow 1 to 2 feet tall by 1 to 1.5 feet wide. The leaves of the Japanese holly fern feel leathery and can have several colors ranging from gold/yellow to gray or green. Japanese Holly fern can be grown in shade and woodland gardens or in any shady or part shady areas with proper soil and drainage conditions. It is resistant to deer and rabbits. Insects, Diseases, and Other Plant Problems: No serious problems but scale, root rot and fungal spots can occur. Watch for Florida Fern Caterpillar.
