All About New York Ferns: Growth and Identification

New York fern (Thelypteris noveboracensis)

This graceful, feathery fern is a favorite for its ability to enhance shady landscapes. Below, we answer some of the most common questions to help you understand and appreciate this beautiful native fern.

Does New York Fern Spread?

Yes, New York ferns spread effectively but are not considered invasive. They propagate through underground rhizomes, gradually forming lush colonies. This spreading habit makes them an excellent choice for ground cover, erosion control, or filling in shaded garden areas. They are particularly suited for naturalistic or woodland gardens where their slow but steady growth adds texture and softness to the landscape.

>What is the Difference Between a New York Fern and a Lady Fern?

While New York ferns and lady ferns (Athyrium filix-femina) share similar environments, they are distinct in several ways: Leaf Shape: New York ferns have a distinctive tapering frond, narrowing at both the tip and the base. Lady ferns have more uniformly shaped fronds that are broader in the middle. 

Growth Habit:

New York ferns spread more aggressively, forming colonies, whereas lady ferns grow in clumps and are less likely to spread.

Color:

New York ferns often have a lighter green hue, while lady ferns tend to be a deeper green. Texture: Lady fern fronds are more finely divided, giving them a delicate, lacy appearance compared to the smoother texture of New York ferns.

What is the Name of the New York Fern?

The botanical name of the New York fern is Thelypteris noveboracensis. This name reflects its native range, as it is found abundantly in the woodlands and shaded areas of the eastern United States, including New York. The name honors its association with this iconic state while also celebrating its widespread appeal.

What is the Difference Between a Marsh Fern and a New York Fern?

The marsh fern (Thelypteris palustris) and the New York fern are closely related but have key differences:

Habitat:

Marsh ferns thrive in wetter environments like swamps and bogs, whereas New York ferns prefer well-drained soils in shaded woodlands. Frond Shape: Marsh ferns have more upright fronds with a uniform width from base to tip.

New York ferns taper at both ends, giving them a more elegant, feather-like appearance.

strong>Growth:

Marsh ferns form looser colonies, while New York ferns spread more densely, creating a fuller ground cover effect.
