Osmunda cinnamomea, or the Cinnamon Fern, is a 3-5' tall fern featuring vibrant green, infertile fronds and cinnamon brown, fertile fronds that appear in early spring. Its roots are black and fibrous, creating a thick mat over time which is useful in erosion control along streambanks and hillsides. Insect larvae feeds on the fronds and the plant is tolerant to salt, deer, and black walnut.



Plant in moist, rich, and acidic soils in full shade to partial shade. Cinnamon Fern can tolerate full sun, but will need regular watering and consistent moist soils as it cannot tolerate summer heat in hotter climates. The plant can be propagated by division every few years in the spring.
