Species of fern

Adiantum capillus veneris, the Southern maidenhair fern, black maidenhair fern, maidenhair fern, and venus hair fern, is a species of ferns in the genus Adiantum and the family Pteridaceae

Adiantum capillus veneris is native to the southern half of the United States from California to the Atlantic coast, through Mexico and Central America, to South America. It is also native to Eurasia, the Levant in Western Asia, and Australasia. There are two disjunct occurrences in the northern part of North America: at Cascade Springs in the Black Hills of South Dakota and Fairmont Hot Springs, British Columbia. In both instances, the warm microclimate created by hot mineral springs permits the growth of the plant far north of its normal range. It is similar in Zvonce spa resort (Звоначка Бања, Zvonačka Banja), near Pirot in Serbia, where hot mineral springs provide adequate heat and humidity for the survival of this species. It is found in temperate climates from warm temperate to tropical, where the moisture content is high but not saturating, in the moist, well drained sand, loam or limestone of many habitats, including rainforests, shrub and woodlands, broadleaf and coniferous forests, and desert cliff seeps, and springs. It often may be seen growing on moist, sheltered and shaded sandstone or limestone formations, generally south facing in the southern hemisphere, north facing in the north, or in gorges. On moist sandstone cliffs it grows in full or partial shade, even when unprotected.

Adiantum capillus veneris grows from in height; its fronds arising in clusters from creeping rhizomes tall, with very delicate, light green fronds much subdivided into pinnae long and broad; the frond rachis is black and wiry. As a houseplant, Adiantum capillus veneris requires filtered light and very humid conditions. It should be grown in soil rich in organic matter and should be watered frequently but lightly, to keep the roots damp but not drenched. The temperature should not fall below It is propagated by dividing, making sure each clump has a section of rhizome.

The fern is listed as an endangered species in North Carolina (as southern maidenhair fern) and threatened species in Kentucky (as venus hair fern), due to loss of Appalachian habitat.

This plant is used medicinally by Native Americans. The Mahuna people use the plant internally for rheumatism, and the Navajo people of Kayenta, AZ use an infusion of the plant as a lotion for bumblebee and centipede stings. The Navajo people also smoke it or take it internally to treat mental illness. Along with this, they have a wide range of medicinal uses and have been used to treat coughs, cold, and to aid in kidney function.
