Ostrich Fern   Pteretis pensylvanica

This vase-shaped common fern, the largest in the area, reaches heights of five to eight feet. Named for its large fronds, which resemble ostrich plumes, it spreads rapidly in moist locations – its underground rhizomes emerging some distance from the mother plant and sending up small baby fronds. Its roots help anchor the soil in wetlands areas, where its growth can be aggressive.
