General Culture:
Winter hardy to USDA Zones 6-10. Grow in moist, humusy, well-drained soils in part shade to full shade. Good soil drainage is essential to protect roots from rotting in winter. Crowns may be mulched with straw in winter. Site in a sheltered location in the St. Louis area where plants are not reliably winter hardy. Tolerance for dry air qualifies this plant for use as a houseplant.
Noteworthy Characteristics:
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. Spores are easily carried by wind, and species plants have escaped gardens and naturalized in certain areas of the southeastern U. S. Genus name comes from the Greek kyrtos meaning arched in reference to the fern habit.
Problems:
No serious insect or disease problems. Susceptible to root rot, fungal spots and scale.
Uses:
Woodland areas and shaded areas of borders or rock gardens. Border for tree or shrub areas. May be grown as a houseplant.
