How to identify Rock polypody (Polypodium virginianum)
Rock polypody, also known as Rockcap Fern, Common Rockcap Fern
Rock polypody is an evergreen fern characterized by its mat-forming growth and resilience in dry conditions. Its fronds are distinctive, notable for being broadest near the middle, tapering gently towards both the apex and base. The foliage maintains a lush presence throughout the year. Leaflets, called pinnae, display a simple and elegant unfurling along the fronds, which typically reach lengths of up to 1.5 feet (45 cm). Despite its visual similarity to its close relative, rock polypody can be differentiated by the placement of its widest leaf blade section.
