Description

Most commonly known as Wood Ferns, they are members of the Polypody family (Polypodiaceae). The native range of this genus is cosmopolitan, found throughout North America and on every continent in the world except Antarctica. Several species are native to North Carolina, including Dryopteris x australis (Dixie Wood Fern), Dryopteris celsa (Log Fern), Dryopteris intermedia (Intermediate Fern), Dryopteris ludoviciana (Southern Woodfern) and Dryopteris marginalis (Marginal Wood Fern).

Quick ID Hints:

  • rachis and costa exhibit continuous grooves on their upper sides
  • indusium is kidney-shaped
  • sori are centrally located on the pinnae
  • stipes have scales

These ferns love to grow in the shade and make a great addition to woodland gardens. They prefer moist, rich, well-drained woodland soil.  A few species are found in swamps, but most do not require wet habitats.
