Create a lush woodland retreat with Woodwardia fimbriata, commonly known as Giant Chain Fern, one of North America's largest native ferns. This impressive semi-evergreen perennial produces magnificent arching fronds reaching 4 to 6 feet tall, bringing bold texture, tropical appeal, and year-round beauty to shaded landscapes.

Native to western North America, Giant Chain Fern thrives in moist, woodland conditions where its graceful fronds create a dramatic backdrop for shade gardens, rain gardens, pond edges, and naturalized landscapes. Its clump-forming habit slowly expands over time, making it an excellent long-term investment for woodland plantings and erosion control.

Low-maintenance, deer resistant, and highly adaptable, this native fern is perfect for gardeners looking to create rich, layered shade gardens filled with beautiful foliage.
