Fern Christmas

Christmas Fern

Polystichum acrostichoides — commonly called Christmas Fern — is a hardy, evergreen fern (perennial) valued for its glossy, dark green fronds and year-round presence. It forms a low, clumping habit with leathery, arching fronds that remain green through winter, often laying flat under snow and re-emerging in spring. New fronds emerge upright in spring, creating a layered, textured look in shaded landscapes.
