Native to central and southern Europe and west Asia,[3] in some parts of North America it is an extremely invasive species.

The flowers are bright blue-violet (rarely white), 2 to 4 centimetres (0.79 to 1.57 in) long, with short petioles standing to one side in the axils of the bracts.

This plant is native to Europe and western Siberia,[6] where it grows in semi-shaded areas like open woods, the edges of denser forests, and meadowland.

[3] It has been introduced to North America, where it has become an extremely invasive weed;[7] it chokes out other plants, and eliminating it is nearly impossible due to its multiple propagation mechanisms.

[10] It grows on grassy places, dry hills, meadows, in deciduous and pine forests, woods, fields and roadsides, along railway lines and hedgerows, preferably in partial shade, in dry to moist sites and on clay soils, relatively rich in nitrogen, at an altitude of 0–2,000 metres (0–6,562 ft) above sea level.

Campanula rapunculoides is native to parts of Eurasia, but is a widespread European import to North America, and it is invasive.
