Description of Plant(s) and Culture

Adiantum pedatum: Maidenhair fern is a delicate perennial fern; the creeping rootstock produces leaves from 1 to 2 1/2 feet high, growing on dark, polished stalks which are forked at the top. Each fork bears 3 to 8 long-oblong pinnae, or leaflets, which are themselves divided into smaller oblong segments, or pinnules, which are incised on the upper margin but entire on the lower side.

Adiantum capillus-veneris: There are some eighty varieties of this plant, some of which grow abundantly in Canada and the United Sates. Maidenhair is perennial and is found in deep woods and moist, rich soil. This is a very delicate and graceful flowering fern growing from 12-15 inches high, with a slender, polished stalk. The leaves are aromatic and bitterish.

Legends, Myths and Stories

Maidenhair is used to flavor liqueurs and cordials. The Romans were fascinated by the unusual qualities of the delicate maidenhair fern when it is immersed in water; under water it glistens with a silvery sheen; but when removed, it is perfectly dry, for water will not cling to it. ecause of these seemingly magic qualities, the maidenhair fern in Roman mythology was said to represent the hair of Venus when she arose from the foam of the sea, thus the name maidenhair.

The plant’s Latin genus name Adiantum comes from the Greek words Adian-tum, meaning “unwetted”.

Uses

Historically, herbalists prepared decoctions from the leaves of Adiantum pedatum for coughs, hoarseness, catarrhal complaints, and congestion associated with colds, asthma, and flu. The plant and related species were also utilized in preparations for the hair and scalp, with traditions dating back to antiquity that employed the fern as a hair tonic or scalp lotion intended to address premature baldness.

Native Americans throughout North America similarly used maidenhair as a hair wash to impart shine. In historical herbalism, Adiantum capillus-veneris was likewise recommended for respiratory complaints, including coughs, nasal congestion, flu, catarrh, hoarseness, and asthma.
