The Cinnamon Fern, Osmunda cinnamonea, occurs in moist, boggy ground along streams and on shaded ledges and grows in clumps to 2'-3' tall, but with constant moisture can reach 5' in height. When new fronds appear, they have a cinnamon color. The yellowish-green sterile fronds remain attractive throughout the summer and turn yellow in autumn.
The common name of Cinnamon ferns is in reference to the cinnamon colored fibers found near the fronds base. Osumunda fiber used in the potting of orchids comes from the roots of these ferns. Plant them in a loamy woodland soil in some shade to mimic the natural environment. This fern is used in container plantings, rock gardens, borders, specimen plants and as ground cover. Cinnamon ferns do not have flowers or blooms. This plant tolerates flooding and will grow in wet submerged soils.
