Adiantum aleuticum: Aleutian Maidenhair Fern

Adiantum aleuticum, the Aleutian Maidenhair Fern or Five-fingered Maidenhair, is a stunning, deciduous fern native to western North America and the Aleutian Islands. It has a unique, fan-like architecture: the stipe (stem) splits into two recurved branches, each bearing several finger-like pinnae (leaflets) that are fan-shaped and held horizontally. The wiry stems are black to purple-black. The overall effect is delicate, horizontal, and graceful.

Aleutian Maidenhair requires cool, moist, well-drained, humus-rich soil and bright shade. It is intolerant of heat, drought, and alkaline soils. It is a premier fern for woodland gardens, shaded rockeries, and containers in cool, maritime climates. The horizontal, fan-like fronds create a unique textural layer. Protect from slugs. A jewel for the discerning shade gardener.
