Fern ID: Royal Fern

Cinnamon Fern, which has reproductive parts on separate fertile fronds, and Interrupted Fern, which has reproductive parts on a few middle rows of otherwise green fronds, are relatives of Royal Fern (Osmunda regalis), which has fertile fronds that feature a terminal crown of reproductive parts.  Royal's sterile fronds and leafy portions of fertile fronds are divided into spaced-out, non-lacy pinnules (see below), which give them a unique look among New England ferns.  Royal Fern is large (commonly 3' or taller), grows in clumps, and likes to have its feet wet.
