Osmundastrum cinnamomeum, commonly called cinnamon fern, occurs in moist, boggy ground along streams and on shaded ledges and bluffs. Typically grows in clumps to 2-3' tall, but with constant moisture can reach 5' in height. Separate spore-bearing, stiff, fertile fronds appear in early spring, quickly turning brown. The familiar "fiddleheads" also emerge from the base of the plant and unfurl into large, erect, pinnately-compound, yellowish-green, sterile fronds which remain attractive throughout the summer and turn yellow in autumn.
Easily grown in medium to wet soils in part shade to full shade. Prefers moist, rich, humusy, acidic soils, but adapts to lesser conditions.
