Botanical Name: Cyrtomium falcatum
Holly Fern is eye-catching on its own. But long fronds with thick, shiny green leaflets make this a handsome addition to any indoor plant grouping.
Combine this easy-care fern among variegated foliage plants, such as snow bush, colorful coleus -- or one of the prayer plants.
This fern's leaflets are about 3-4 inches (8-10 cm) long with sawtoothed edges. Although it resembles the holly plant, the two aren't related.
Less fussy about humidity than most common indoor ferns, it flourishes in the home with little care. It is better behaved, too. Unlike many ferns, Cyrtomium falcatum does not shed.
Those green leaflets are naturally glossy. Keep them clean by wiping them off with a damp cloth. Or take it to the sink for a lukewarm shower.
Repot in spring because Holly Fern begins its most vigorous time of growth in summer. When repotting, make sure the crown of the plant is slightly above the soil line to prevent rot. Use a pot with drainage holes so that the soil won't get soggy. Now that you have your fern out of its container, this is a good time to divide it, if you want.
Watch for scale insects, that look like small, brown discs on leaflets. (Sometimes the brown spores on the undersides of leaflets are mistaken for scale. You'll recognize the spores because they appear in two rows under each pinnae.) To remove scale insects, scrape them off with your fingernails. Don't use insecticides on ferns because they are easily damaged by chemicals.
