Interrupted Fern

About Interrupted Fern

Interrupted Fern is a majestic and ancient-looking fern that brings a sense of timelessness to the woodland garden. This large, clump-forming perennial typically reaches heights of two to four feet, with broad, arching fronds that create a lush, tropical feel. It earns its unique name from the 'interruption' in its sterile green fronds: in the middle of the leaf, a few pairs of smaller, dark brown fertile leaflets appear in spring, which eventually wither and fall off, leaving a characteristic gap. Native to moist, rich woodlands and shaded slopes across eastern North America, it is a hardy and long-lived species. While it prefers moist, acidic soils, it is surprisingly adaptable and can tolerate some sun if the soil remains consistently moist. Interrupted Fern provides excellent cover for ground-nesting birds and other small wildlife. Its striking form and interesting reproductive habit make it a fascinating focal point for naturalized areas or large shade gardens.
