Christmas fern is a Missouri native evergreen fern that earns its common name by staying vibrantly green throughout winter, when most other woodland plants fade to dormancy. Polystichum acrostichoides grows in a graceful fountain-like clump reaching 12 to 24 inches tall and wide, with leathery, lance-shaped fronds that display silvery, scaled crosiers (young fiddleheads) in spring. Hardy from zones 3 to 9, this low-maintenance fern thrives in partial shade to full shade and handles dry soil with remarkable resilience, making it equally at home on rocky slopes or beneath dense tree canopies where few other plants flourish.

The stocking-shaped pinnae (leaflets) of Christmas fern's fronds literally look like little Christmas stockings, which is part of why early gardeners treasured this native fern for winter arrangements and holiday decoration. Its evergreen nature means your woodland garden never goes bare, and it's so unfussy that it handles everything from heavy shade to drought and rocky, shallow soil without complaint. Silver crosiers unfurl in spring like tiny curled surprises, offering a delicate counterpoint to the leathery mature fronds that persist year-round.
Christmas fern serves primarily as an ornamental groundcover and woodland accent plant, valued for its year-round evergreen presence in shaded gardens. The fronds have long been used in fresh and dried floral arrangements, particularly for winter and holiday decorating. In native plant landscaping and woodland gardens, it stabilizes soil on slopes and banks while providing textural contrast beneath trees and shrubs.

Transplant Christmas fern into prepared soil in spring or fall, spacing plants 12 to 24 inches apart. Ensure the soil is organically rich and well-draining. Angle the rhizome slightly to promote water drainage away from the crown.
Christmas fern requires minimal pruning. Remove any damaged, diseased, or winter-damaged fronds in early spring to tidy the clump and encourage fresh growth. Since the fronds are evergreen and attractive year-round, preserve them whenever possible.

“Christmas fern is a native North American species found growing wild across wooded slopes, moist banks, and ravines throughout its range. Its common name reflects a long tradition of cutting fronds for Christmas arrangements and holiday decorations, a practice that dates back generations in regions where it grows naturally. The fern was likely introduced to cultivation through this ornamental use, with gardeners transplanting wild specimens or collecting spores to establish it in their own woodland gardens.”
