Polystichum setigerum, commonly known as Alaska Hollyfern, is an evergreen fern native to the understory of temperate rainforests in the Pacific Northwest, including Alaska and British Columbia. It typically grows to a height and width of 2-3 feet (0.6-0.9 meters), featuring glossy, dark green fronds that resemble holly leaves, hence the common name. The fronds are triangular and the plant has a tidy, clumping habit, making it a visually appealing addition to shade gardens.

Alaska Hollyfern is valued for its year-round interest and low maintenance requirements, thriving in the dappled light beneath larger trees. It is an excellent choice for woodland gardens, shaded borders, and as an understory plant in forested areas. It prefers consistently moist, well-drained soil rich in organic matter and can tolerate a range of pH levels. While it is generally pest and disease-free, it can occasionally suffer from fungal diseases in overly wet conditions. This fern is not known for aggressive growth or invasiveness, making it a safe choice for cultivation in a variety of settings.CC BY-SA 4.0
