Adiantum capillus-veneris aka Maidenhair Fern

Adiantum capillus-veneris, also known as the Southern maidenhair fern, black maidenhair fern, maidenhair fern, and Venus hair fern, is a low-growing spreading fern with elegant fronds that are twice divided. Supported on wiry black stems, these fronds have a gentle arching shape. This species of fern belongs to the genus Adiantum and the family Pteridaceae, and it has a subcosmopolitan worldwide distribution. It can be found in various habitats, including rainforests, shrub and woodlands, broadleaf and coniferous forests, and even desert cliff seeps and springs. Adiantum capillus-veneris is native to the southern half of the United States, from California to the Atlantic coast, as well as Mexico, Central America, South America, Eurasia, the Levant in Western Asia, and Australasia. It thrives in temperate climates, ranging from warm-temperate to tropical regions, where the moisture content is high but not saturating. This fern is often cultivated as a popular garden fern and is also commonly kept as a houseplant. In warm sheltered gardens, it can exhibit semi-evergreen characteristics.
