Osmunda regalis - Royal Fern
"Osmunda regalis, commonly called royal fern, is a tall, deciduous, native fern which usually occurs on moist bluffs and ledges and along streams (sometimes growing in the water). Typically grows in clumps to 5-6' tall, but with constant moisture can reach 6' in height. Broad fronds have large, well-separated pinnae (leaflets) which give this fern an almost pea-family appearance. Fronds typically turn yellow to brown in autumn. Spores are located in brown, tassel-like, fertile clusters at the tips of the fronds, thus giving rise to the additional common name of flowering fern for this plant. Osmunda fiber used in the potting of orchids comes from the fibrous roots of these ferns.
"It is best grown in medium to wet soils in part shade. It prefers moist, rich, humusy, acidic soils, but adapts to lesser conditions. Also prefers cool summer climates where it tolerates close to full sun as long as given consistent moisture. Full sun exposure is not recommended." (North Carolina Extension)
