Clustered Bellflower, Yorkshire


In southern Britain, the availabiliuty of dry alkaline grassland largely determines the distribution of Clustered Bellflower, which is most commonly seen on the chalk downlands of southern England and limestone habitats in central and northern parts of eastern England. In Wales and in southern Scotland this is a rare sight and mainly a coastal wildflower, while it is absent from the far north and west of Scotland.

On mainland Europe and Asia, Clustered Bellflower is widely distributed and fairly common except for the extreme northern countries.

Flowering times

Clustered Bellflower produces neat columns of flowers from June through to September. The specimens shown on this page were seen in Yorkshire in late June.
