The marginal shield fern or marginal wood fern is native to the moist woodlands of eastern north America where it is found in shaded nooks around rocks and fallen trees. It has medium green leathery leaves and can grow to 2 feet in height with a similar spread. The marginal wood fern prefers humus-rich soil and will tolerate a full shade location. This fern would be a suitable addition to a native or woodland garden or a understory planting.
