About Cinnamon Fern

Cindy fern occurs in the moist, boggy ground along streams and on shaded ledges and bluffs. It typically grows in clumps to 2-3' tall, but with constant moisture can reach 6' tall. The common name of this plant is in reference to the cinnamon-colored fibers found near the frond bases. Osmunda fiber used in the potting of orchids comes from the roots of these ferns.
