Athyrium is a genus of ferns commonly known as lady ferns. These plants are characterized by their delicate, feathery fronds that can vary in size and shape. They thrive in moist, shaded environments, often found in woodlands and along stream banks. Lady ferns are popular in gardens and landscaping due to their attractive appearance and ability to tolerate a range of soil types. They reproduce through spores, which are produced on the undersides of their fronds. Athyrium species are also important for maintaining biodiversity in their native habitats.
