Saxifraga × urbium, London pride, is an evergreen perennial garden flowering plant.

Near Dunloe in County Kerry "heareabouts grew quantities of our London Pride, and upon my expressing a wish for some roots to carry home, Sullivan [the driver] sprang down and tore up a large tuft.

It will grow well in neglected or unfavourable urban spaces where few other flowers flourish, and is a common garden escapee.

[1] Tradition holds that Saxifraga × urbium rapidly colonised the bombed sites left by the London Blitz of the early 1940s.

A song by Noël Coward, celebrating London and the flower, achieved great popularity during the World War II years.
