Sensitive Fern

About Sensitive Fern

Sensitive Fern is a charming and adaptable addition to any damp, shaded landscape. Reaching heights of up to three or four feet, this fern is easily identified by its broad, leathery, light green sterile fronds that feature deeply cut, wavy-edged lobes. It earns its common name from its extreme sensitivity to the first frost of autumn, which causes the sterile fronds to wither almost immediately. However, its fertile fronds are remarkably hardy, standing tall through the winter with dark, bead-like structures that protect the spores. Native to wetlands and moist woodlands across eastern North America and parts of Asia, it thrives in wet to medium-wet soils and can handle anything from full sun to deep shade, provided it stays hydrated. This fern is an excellent choice for stabilizing soil in rain gardens or along pond edges, where its creeping rhizomes help form a lush groundcover. While not a primary food source, its dense growth provides valuable cover for amphibians and small wildlife in wetland ecosystems.
