Plant Profile: Dryopteris marginalis

Dryopteris marginalis, commonly known as the marginal shield fern, is an evergreen plant that typically develops into a non-spreading, vase-shaped clump, reaching heights of 1.5 to 2 feet, and occasionally up to 3 feet. This fern thrives in woodland environments, often found nestled in the shaded crevices of rocky ledges and bluffs. It showcases grayish-green, deeply lobed, leathery fronds that can grow between 15 to 20 inches long. The sori, or spore cases, are situated along the edges of the undersides of the pinnules, which is the origin of its common name. The plant's rhizome creates an upright crown, and its evergreen fronds add visual interest to winter landscapes.

This fern prefers moist, well-drained, humus-rich soil and thrives in partial to full shade. It features a broad, upright crown that is densely covered with light brown scales and typically forms a large, singular crown without spreading. It is quite hardy and can be easily cultivated in average, medium, well-drained soil under part to full shade conditions. Ideal growing conditions include moist, rich, humusy, and acidic soils, along with protection from wind.
