Osmunda regalis L.
Osmundaceae (Royal Fern Family)
The form and texture of this fern
are unique. The fronds are cut twice into large rounded leaflets, resulting in foliage that resembles that of the pea family. Delicate, bright green fronds, often with a silvery cast, are crowned with golden, fruiting pinnae
on wine-colored petioles. Fronds are 2-5 ft. in height and often 18 in. in width. Rootstock elevated up to 6 inches above the soil surface, with black roots extending deep.
