This fern can be confused with Hayscented fern, however Hayscented fern has a triangle-shaped frond that is broadest at the base, as compared to New York Fern that is tapered at the base.
“New York Fern has a tendency to form large, dense colonies that can reduce the diversity of woodland herbs and inhibit the establishment of woody plants.”
It is very pretty though!
