Asplenium trichomanes, commonly known as the maidenhair spleenwort, is a small, evergreen fern with a huge native distribution, including Europe, Asia, North America, Central and South America. A number of sub-species exist, each suited to growing in varying growing conditions, often in well-drained, rocky habitats. In the garden, Asplenium trichomanes is fantastic for growing in rockeries, in brick and stone walls or among stepping stones in shady spots.
