This rhizomatous perennial herb is a frequent garden escape or throw-out, occurring in grassy places on roadsides and railway banks, in hedge banks and wood-borders, usually close to habitation and showing a strong preference for warm, sheltered, often somewhat shaded situations. Lowland.
Cultivated in Britain by 1629, G. versicolor has been known in the wild since 1820. It is now better recorded and more widespread than when mapped in the 1962 Atlas.
