Summary

Parathelypteris noveboracensis, commonly known as New York Fern, is a deciduous perennial herb that thrives in the understory of moist deciduous forests, often forming extensive colonies. It is native to the Eastern United States and Canada, particularly in areas with rich, moist, well-drained soil. The fern typically grows in clumps with fronds emerging from a dark brown, slightly scaly rhizome. Each frond measures 8–25 inches (20–64 cm) in length, is yellow-green, and has a soft, thin texture. The fronds are unique in that they taper at both ends, with the lowest 4-10 leaflets being generally smaller than those above, giving them a distinctive appearance.

New York Fern is valued for its ability to spread and form lush green ground cover in shaded garden areas. It is an excellent choice for woodland gardens, shaded borders, and naturalized areas where it can create a carpet-like effect. This fern is a wetland indicator, signifying the presence of wetlands when found in the wild, and is considered an endangered species in Illinois. It prefers part shade to full shade and requires consistently moist soil, though it is adaptable to various drainage conditions. While it is low-maintenance, it can be sensitive to drought and may require additional watering during dry spells.CC BY-SA 4.0
