Bright green, lacy, broad leaves appear in early spring. The pinna are narrow, lance-shaped, pointed, deeply cut and nearly opposite. Sterile fronds are lanceolate, pinnate-pinnatifid with dense rusty hairs beneath the base of each pinna.

The common name of this plant is in reference to the cinnamon-colored fibers found near the frond bases. The familiar "fiddleheads" also emerge from the base of the plant and unfurl into large, erect, pinnately-compound, yellowish-green, sterile fronds (2-4' long) which remain attractive throughout the summer and turn yellow in autumn. Separate spore-bearing, stiff, fertile fronds appear in early spring, quickly turning brown. 
It typically grows in clumps to 2-3' tall, but with constant moisture can reach 6' in height. Phonetic Spelling os-MUN-duh-strum sin-uh-MOH-mee-um DescriptionĬinnamon fern is a native fern which occurs in the moist, boggy ground along streams and on shaded ledges and bluffs.
