plant sale text: Christmas fern is easily grown in a variety of soils, and tolerates partial to full shade. This SE native fern is commonly seen growing in woodlands throughout North Carolina. Its leathery evergreen fronds bear stocking-shaped pinnae, which is one explanation for how it got its common name. Established plants grow into sizable clumps that add color and interest to the shade garden throughout the year. Christmas fern can be planted singly as an accent, or en masse as a ground cover.
