Botanical Name

CAMPANULA glomerata 'Superba'

Plant Common Name

Clustered Bellflower, Dane's Blood

General Description

Clustered bellflower is a vigorous, spreading perennial native to much of Europe and Asia. The seed-grown cultivar 'Superba' bears dramatic dense clusters of rich purple, bell-shaped flowers. They bloom from late spring into summer on stout reddish stems with broad hairy leaves.

Grow 'Superba' in moist but well-drained soil in sun to partial shade. Cut back the spent flower stems to encourage repeat bloom. It's a splendid plant for the middle or back of the perennial border.
