Marsh Fern (Thelypteris palustris) is a graceful, moisture-loving native fern that thrives in wetland areas and naturalized shade gardens. Its finely divided, bright green fronds a dd delicate texture and movement to the landscape from spring through fall. Ideal for rain gardens, boggy borders, or woodland edges, this deciduous fern spreads by rhizomes to form lush colonies, making it excellent for erosion control and groundcover in damp, low-lying areas. This hardy fern reaches a mature size of 1 to 3 feet tall and wide, thriving in USDA Hardiness Zones 3–7. Marsh Fern prefers partial to full shade and grows best in consistently moist to wet, acidic soils rich in organic matter. It's deer-resistant, low-maintenance, and tolerant of seasonal flooding, making it a reliable and attractive choice for ecologically-minded gardeners. Whether you're restoring a native habitat or adding lush foliage to a shady spot, Thelypteris palustris brings natural beauty and resilience to any landscape. Show more
