Cinnamon Fern

'Cinnamon' Fern

Cinnamon Fern is a bold, dramatic fern known for its large, arching fronds and striking cinnamon-colored fertile spikes that rise from the center of the plant in spring. These fertile fronds emerge upright and rusty-brown, resembling cinnamon sticks giving the fern its memorable name, while the surrounding sterile fronds unfurl into soft, bright green plumes. This lush texture and vertical interest make it a show-stopping addition to shady or woodland gardens.

Reaching up to 3 to 5 feet tall in ideal conditions, ‘Cinnamon’ Fern thrives in moist, rich soils and partial to full shade. It’s especially well-suited to rain gardens, stream banks, and other damp, shaded areas, where it can spread gradually through underground rhizomes to form impressive colonies. Despite its preference for moisture, it’s more adaptable than many ferns and can tolerate drier conditions once established, especially in cooler climates.

A native North American species, Cinnamon Fern adds a naturalistic, forest-like atmosphere to gardens and supports local biodiversity. It’s highly deer-resistant and low-maintenance and offers multi-season appeal, from the dramatic emergence of its fertile fronds in spring to the vibrant green summer foliage and golden tones in fall. Ideal for native plantings, woodland edges, or naturalized shady borders, Cinnamon Fern brings structure, texture, and ecological value to the landscape.
