A perennial herb, commonly cultivated and widely naturalised in Britain, less so in Ireland. It is most frequently found rooted into the crevices of old mortared walls, pavements and other masonry, and on brick rubble and stony waste ground. Once established in an area, it can quickly colonise new sites. Generally lowland, but reaching 305 m at Great Hucklow (Derbys.).
P. lutea was being grown in Britain by 1596; it was first recorded in the wild in 1796 and became widespread in the early 1800s. Since the 1962 Atlas it has clearly increased in some areas, such as Wales and S.W. England.
Native of the southern foothills of the S.W. & C. Alps; widely naturalised elsewhere in Europe.
