Description

American Climbing Fern is native to the Eastern United States but is considered threatened in many states. It requires high light levels, constant moisture and acidic soils as is found in thickets, bogs, marshes, and open and closed woods. This plant is found primarily in the Appalachian Mountains area.

It is known as Hartford Fern because it was the first plant to be protected by law in the United States in Connecticut due to it being gathered for Christmas decorations.
