Osmundastrum cinnamomeum

Native Plants

Cinnamon Fern

3 Photos


Cinnamon fern (Osmundastrum cinnamomeum) features showy, cinnamon-colored fertile fronds in early spring followed by large arching sterile fronds for the remainder of the growing season, making this an attractive addition to the moist shade garden. The erect fronds grow to 3½’ tall with the fertile fronds fading by early summer. Cinnamon fern thrives in moist, humus-rich, acidic to average soil in partial to full shade and its fibrous root system is excellent at holding the soil in place, especially streamside. Cinnamon fern makes an excellent companion to golden ragwort (Packera aurea),swamp pink (Helonias bullata), swamp saxifrage (Micranthes pensylvanica), Gray’s sedge (Carex grayi), and great blue lobelia (Lobelia siphilitica). Zones 3-9.
