About
Adiantum capillus-veneris, the maidenhair fern, southern maidenhair fern, black maidenhair fern and venus hair fern, is a species of ferns in the genus Adiantum and the family Pteridaceae with a subcosmopolitan worldwide distribution. It is cultivated as a popular garden fern and houseplant.
How to grow it
Adiantum capillus-veneris is cultivated and widely available around the world for planting in natural landscape native plants and traditional shade gardens, for outdoor container gardens, and commonly as an indoor houseplant.
Adiantum × mairisii is a winter hardy hybrid of Adiantum capillus-veneris with another species, which is likely to be one of Adiantum raddianum, Adiantum aethiopicum, or Adiantum cuneatum.
Where it grows
Adiantum capillus-veneris is native to humid warm temperate to tropical regions globally. It occurs in western and southern Europe (north to southern Scotland, where its northernmost sites are found), much of Africa, the Levant and across Asia to Japan, in Australasia, and in the Americas in the southern half of the United States from California to the Atlantic coast, through Mexico and Central America, to South America. 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.
