Cinnamon Fern

Cinnamon Fern is a dramatic, vase-shaped native fern prized for its architectural foliage and seasonal interest. It thrives in consistently moist, acidic soils and is typically found in shaded streambanks, bogs, and woodland edges throughout much of eastern North America.

Reaching 3 to 5 feet tall, it produces bright green sterile fronds that emerge in a fountain-like form, with fertile fronds rising from the center, colored a rich cinnamon-brown — a feature that gives the plant its common name. The emerging fiddleheads in spring are a striking bronze and add a textural dynamic to early-season gardens.

Cinnamon Fern provides essential cover and moisture retention in shady ecological plantings. Its dense clumps offer shelter for amphibians and ground-nesting birds. While not a host plant for many insects, it contributes to the microclimate of woodland habitats and resists deer browsing.

• Watering: Prefers consistently moist to wet soils—do not allow it to dry out.
• Sunlight: Best in part to full shade, though it can tolerate morning sun if soil is wet enough.
• Trimming: Cut back old fronds in late winter or early spring before new growth emerges.
• Spacing: Allow space for clump expansion over time; can grow quite wide.
• Division: Can be divided every few years in early spring if needed, though slow to reestablish.
