Athyrium is a genus of ferns that includes about 200 different species. Some synonyms for the word athyrium are lady fern, lace fern, and buckler fern. Lady ferns are typically characterized by their delicate, lacy foliage and are commonly grown as ornamental plants in gardens. Lace ferns have a more delicate appearance than many other fern varieties, with finely cut fronds that resemble delicate lace. Buckler ferns, on the other hand, have sturdier leaves that are often used for medicinal purposes. Regardless of the specific synonym used, athyrium ferns are beautiful, versatile plants that can add interest and texture to any landscape or indoor setting.
