This autumn-germinating annual is found mainly in sites associated with human activity. Habitats include walls, gravel paths, paving, railway tracks and gardens. It does not occur in arable land. Lowland.
V. carinata has greatly increased since the 1962 Atlas, and it is now more common than V. locusta in some areas, especially S.W. England. It is difficult to account for such a dramatic increase, which cannot be entirely due to the fact that the differentiating characters are now better known.
As an archaeophyte V. carinata has a European Southern-temperate distribution.
