About
Cyrtomium falcatum is a species of fern, commonly known as house holly-fern and Japanese holly fern, in the wood fern family Dryopteridaceae. It is native to eastern Asia.
It grows from crevices in coastal cliffs, stream banks, rocky slopes, and other moist, stable areas.
How to grow it
Cyrtomium falcatum is a fairly common outdoor ornamental plant in temperate climates (zones 6 to 10), such as in the coastal counties of California; it is more common as an indoor houseplant in areas with very cold or hot conditions. The holly fern is reliably hardy compared to many other, more tropical species of fern; outdoors, it thrives in locations of low indirect light to deep shade, such as underneath trees or bushes. It may be propagated by spores, but is more commonly multiplied via rhizome division, rooting the fresh cuttings in a substrate of coconut fiber, sphagnum moss, or another well-aerated substrate. The cuttings should be kept evenly moist and shaded but not sitting in a pool of water.
Holly ferns planted either in containers or in the ground are not picky about soil composition or quality; like other ferns, they will even grow mounted or tied to driftwood, wooden boards, tree branches or rocks, provided there is some amount of sphagnum moss or other organic medium surrounding the rhizome and rootball and the plant receives adequate water.
