Campanula glomerata 'Superba': Clustered Bellflower – Bold Purple Clusters for Early Summer

Campanula glomerata 'Superba' – Superba Clustered Bellflower

Campanula glomerata 'Superba' (also known as 'Dahurica') is a robust, clump-forming perennial that produces dense, spherical clusters of deep violet-purple, bell-shaped flowers atop sturdy stems in early summer. The blooms are held above a basal rosette of coarse, dark green leaves. It makes a bold statement in the early summer border and is excellent for cutting.

Clustered Bellflower thrives in full sun to partial shade and moist, well-drained soil. It spreads steadily by rhizomes, so give it room or plant where its colonizing habit is desired. 'Superba' is a particularly vigorous and floriferous selection. After flowering, cut back stems to tidy the plant and prevent excessive self-seeding. A classic, reliable perennial for cottage gardens and mixed borders.
