Adiantum aleuticum
Also called Aleutian Maidenhair Fern, Five Finger Fern, Northern Maidenhair, Western Maidenhair, Fivefinger Fern, Five Fingered Fern, Serpentine Maidenhair
Aleutian maidenhair is a hardy, deciduous fern of cool, moist rock crevices and streambanks in western North America. It grows well in the garden or indoors when kept moist and given low to medium light.
Adiantum aleuticum, the western maidenhair fern or Aleutian maidenhair, is a species of deciduous fern in the genus Adiantum.
The species
and its cultivar 'Subpumilum' have gained the Royal Horticultural Society's Award of Garden Merit. Though hardy they may also be grown as houseplants. They prefer low to medium light, and will grow in moist potting mix. They may prove difficult to keep alive in dry climates.
Adiantum aleuticum is native mainly to western North America from the Aleutian Islands of Alaska, south to Chihuahua, and also locally in northeastern North America from Newfoundland south to Vermont. It prefers fertile, moist soil in rock crevices near streams, from sea level in the north of its range, up to 3,200 m altitude in the south of its range. It tolerates serpentinite rock well, and is confined to this mineral-rich rock in some areas. When growing on sunny serpentine talus and bedrock, the fronds are held vertically, giving the fern a rather different general appearance.
