|This evergreen fern has erect, triangular-shaped, deeply cut, 2 to 4 pinnate leaves that reach up to 3 feet long. Long purplish-black stalks emerge from long, creeping rhizomes and plant can spread more than 6 feet. Fronds often emerge pale green and darken with age. Best suited to temperatures above 45 degrees Fahrenheit, thus often used as a houseplant. It is very important that this fern does not dry out, so water when top of soil is dry to the touch. Frequent misting is welcomed also. Filtered sun or bright light from an east window is preferable. Fertilize with half strength, quick-release solution during growing season. Cut out dead or damaged fronds in spring.
