Cinnamon fern (Osmunda cinnamomea) is a Missouri native and is a recommended fern variety by professional landscapers. While non-flowering， they are grown for their green deciduous fronds that provide dramatic effect. The familiar "fiddleheads" emerge from the base of the plant and unfurl into large， erect， yellowish-green， sterile fronds that remain attractive throughout summer. The common name of this plant is in reference to the cinnamon colored fibers found near the frond base. Fun fact: Osmunda fiber used in the potting of orchids comes from the roots of these ferns.
