A shrub or small tree typically occurring in ancient woods, wood-borders, old hedgerows and boundary banks on clay soils. It appears to be more tolerant of shade than C. monogyna. Lowland.
The frequency of C. laevigata has changed little in its core range since the 1962 Atlas, but there are now many scattered new records beyond that area. It is widely planted both inside and outside its core area, and most of the new records must relate to planted populations. C. laevigata is not always easy to distinguish from C. x media, and some records may be errors for the hybrid.
European Temperate element.
