Typical Landscape Use
The cinnamon colored fertile fronds are often used as everlastings in dried flower arrangements.
Establishment and Care Instructions
Shade to partially shaded areas and good moisture are definitely preferred. Adaptable to less wet conditions, although it will appear stunted and stiff and the showy fertile fronds will be "hidden" inside the crown.

Basic Description

This tall fern has large medium-green fronds and a stately, gracefully curved, upright habit with separate, showy cinnamon brown fertile fronds that emerge from the center of the plant. The best way to distinguish this fern from the Ostrich Fern is by the fertile fronds that appear in May and mature by mid-June. Ostrich fern has dark green, fertile fronds that ripen in July. Also, the pinnae (leaflets) of the Cinnamon fern have tufts of rusty-colored ‘wool’ at their bases.
