This biennial or short-lived perennial herb is found on road verges and embankments, in hedge banks and other grassy places, on walls and in cultivated ground, including arable field margins. It prefers well-drained calcareous soils. 0-335 m (Brassington, Derbys.).
V. nigrum is a mobile species; changes in the management of hedge banks and roadsides may be responsible for local losses, but can also be of benefit in assisting the dispersal of seed to new areas. This species is often grown in gardens, and the distinction between native and alien populations has become more blurred as garden escapes become more frequent.
