A perennial, stoloniferous herb, found growing only in damp, shaded places, such as woods, N.-facing cliffs and banks, and by streams and on rocks in the mountains. Naturalised populations in Britain, often derived from garden escapes, are often found on limestone, whereas in its native Ireland the species occurs only on siliceous rock. 0?915 m (Mt Brandon, S. Kerry).
There has been no appreciable change in the native range of S. hirsuta since the 1962 Atlas, although naturalised populations in Britain have increased considerably, especially in the north and west.
Oceanic Temperate element.
