Campanula poscharskyana ‘E.H. Frost’
A trailing bellflower producing small white flowers lightly flushed with blue from early summer into autumn. The flexible stems weave easily through neighbouring plants or spill over walls and edges, creating a soft, informal effect. Best used where its spreading habit can be accommodated and guided rather than constrained.
