Evergreen Woodfern

Dryopteris intermedia (dry-OP-ter-iss in-ter-MEE-dee-ah)

Family: Dryopteridaceae Native Herbaceous (3-15 ft)

The evergreen woodfern is in the polypody family (Polypodiaceae). The fern is native to the eastern half of North America. The species epithet is Latin for “intermediate,” the meaning of which was unexplained at the time the species was named. It prefers moist, shady sites but will tolerate dryish conditions on a short term basis. This fern does not spread. Plant in an area protected from strong winds that may damage the fronds.The fern grows in clay or loamy, rich acidic soil. It can take dappled light to deep shade. This fern is easy to grow. Its fronds are evergreen to semi-evergreen in climates that experience mild winters. In locations where it is not evergreen, the old fronds should be removed during the winter months before the new spring growth begins. The evergreen wood fern can be grown in native or shade gardens, in woodlands, or in moist rocky areas. Insects, Diseases, and Other Plant Problems: No serious issues.
