Polystichum acrostichoides (Christmas Fern)
Christmas Fern, Dagger FernPolystichum acrostichoides, commonly known as Christmas Fern, is a versatile and resilient fern that adds year-round greenery to gardens and landscapes. This evergreen fern derives its name from its fronds, which often remain lush and green even during the winter months, making it a popular choice for holiday arrangements. Native to eastern North America, it thrives in shaded areas and is well-suited for woodland gardens, shaded borders, and erosion control on slopes.
The Christmas Fern typically grows in an attractive clump, reaching 1–2 feet in height with a similar spread. Its dark green, leathery fronds have a lance-shaped structure, adding a classic and elegant texture to any planting design. Beyond its ornamental value, the plant is deer-resistant, low-maintenance, and contributes to ecological health by preventing soil erosion.
