Summary
Cyrtomium falcatum—most commonly known as the Japanese Holly Fern, and sometimes as the Fishtail Fern—is best known for its dense, stiff, attractive, olive-green foliage that's evergreen in areas of warmer winters! Its serrated-edged leaflets closely resemble the foliage of a Holly Tree; hence the name.
Ferns are fantastic air-purifying plants, and are known to help remove many of the most common airborne toxins and VOCs such as formaldehyde, xylene, and toluene.
Japanese Holly Fern grows into somewhat of a mound-like shape over time, and is absolutely excellent for use as specimen plants, groundcover or as a border edging in shadier locations!
Thrives when potted as an indoor plant, in a hanging basket, as a patio plant, or planted outdoors in appropriate zones.
Care
Japanese Holly Fern Care
Cyrtomium falcatum thrives in shaded areas. Avoid exposure to full, strong sun.
Japanese Holly Fern may be grown as an outdoor perennial fern when planted in hardiness zones 6-10.
Prefers soil full of rich, organic compounds. Avoid soil with poor drainage as root rot may likely occur if planted in such.
Attempt to keep soil slightly moist but not wet. Please be aware that indoor grown Japanese Holly Ferns will drink considerably less over the winter than over the summer.
This plant does best in moderate temperatures between 55°F and 85°F.
Japanese Holly Fern is a deciduous plant. As such, it will lose its fronds as winter approaches when grown in colder (appropriate) zones. Many individuals choose to trim and remove dead fronds over winter. Fronds will return will vigor and fullness in the spring.
Needs very little to no fertilizer depending on soil conditions. Use caution when fertilizing and apply fertilizer at 1/4 strength max.
