Easily grown in average, medium, well-drained soil in full sun to part shade. Prefers part shade in hot summer climates. Needs regular moisture. Promptly remove spent flower stems to encourage additional bloom. Divide clumps in fall every 3-5 years to maintain vigor and/or control spread. Plants may be grown from seed, and may self-seed somewhat rapidly to the point of being weedy under ideal growing conditions.
This clustered bellflower variety is an upright, clump-forming perennial which typically grows 1.5-2' tall on erect, branching stems. Ovate to lance-shaped, toothed, somewhat hairy, medium green basal leaves (to 5" long) with shorter stem leaves. Upward facing, bell-shaped, white flowers (to 1.5" long) appear primarily in terminal spherical clusters atop the stems, with smaller flower clusters blooming in the upper leaf axils. Main bloom is in late spring to early summer. Clusters can have up to 15 flowers each, hence the common name. This variety is basically a white-flowered version of the popular purple-flowered Campanula glomerata 'Superba'.
No serious insect or disease problems. Snails and slugs are occasional visitors.
Group or mass. Rock gardens, borders, cottage gardens or informal naturalized areas.
