An evergreen, perennial, rhizomatous fern of well-drained, predominantly acidic substrates, including dry-stone walls, roadside banks and rock outcrops. It also occurs as an epiphyte on Quercus and other deciduous trees, mainly in W. Britain and Ireland, and is also found in conifer plantations. It is very tolerant of exposure, growing, for example, on montane scree. 0?760 m (Beinn na Socaich, Westerness).
There is little evidence for any change in the distribution of P. vulgare sens. str. It is probably under-recorded in Ireland and in some areas of Scotland but is rarer than P. interjectum in S.E. England.
European Boreo-temperate element.
