With fronds usually up to 20cm long and short round leaves, maidenhair spleenwort has an attractive and delicate appearance that makes it popular with gardeners. It grows readily on both natural and manmade rock and stone surfaces throughout the British Isles.
In the Yorkshire Dales National Park, maidenhair spleenwort is commonly found in many limestone habitats, such as rocky outcrops, scars, cliff faces and even on buildings constructed from limestone.
There are three maidenhair spleenwort sub-species found in the British Isles. It is the subspecies quadrivalens which is commonly found on calcareous rock surfaces within the Yorkshire Dales National Park.
