A rhizomatous perennial herb, found as a garden escape on grassy banks, verges and waste ground, mainly in urban areas. Once established, it is persistent. Lowland.
Neophyte. G. himalayense is increasingly grown in gardens, where it has been grown since the 1880s. It was first recorded from the wild in Britain in 1976 (W. Kent). It may have been under-recorded because of its similarity to G. pratense. Another overlooked garden escape, possibly mistaken for either this species or G.pratense, is the popular garden hybrid G. himalayense × G. pratense `Johnson`s Blue`.
Native of the Himalayas.
