Plant
Walking Fern
Asplenium rhizophyllumAlso known as American Walking Fern
Walking ferns earn their name from an unusual habit of rooting from the elongated tips of their arching fronds, creating new plantlets that form dense, interconnected colonies over time. They thrive on shaded, moss-covered limestone outcrops and damp cliff faces across eastern North America. Their simple, narrow fronds remain green year-round, anchoring firmly into rocky crevices where few other plants take hold.
