Saxifraga spathularis x umbrosa (S. x urbium)
A perennial, stoloniferous herb, usually growing in shaded or at least damp places in woods, by streams, on banks and walls, and among rocks. Generally lowland, but reaching 335 m at Parsley Hay (Derbys.).
S. x urbium is known to have been grown in Britain before 1700. It has escaped and become established in suitable places throughout our area, despite being shy-fruiting owing to sterility in the majority of specimens. It was recorded from the wild in 1837 (Staffs.).
A hybrid of garden origin.
