My first experience with the sterile Adiantum x mairisii was in 1993, thanks to a gift from the late fern collector Nancy Swell of Virginia. Not to be confused with the Chinese Adiantum mariesii, this reported hybrid of Adiantum capillus-veneris and an unknown baby daddy was discovered around 1885 at the UK's Mairis & Co. Nursery and subsequently named by Chelsea Physic Garden curator and fern collector Thomas Moore. Adiantum x mairisii performs like a vigorous clone of southern maidenhair fern but with very good winter hardiness. For us, expect a 3' wide deer-resistant patch of 1' tall, lacy maidenhair foliage in 5 years.
