Easily grown in average, medium, well-drained soil in full sun to part shade. Prefers part shade in warmer climates. Does not do well when night temperatures in summer remain consistently above 70 F degrees, although this cultivar has better heat tolerance than many of the other campanulas. Needs regular moisture. Divide clumps in fall every 3-4 years.
This clustered bellflower cultivar is an upright, clump-forming perennial which typically grows 2-2.5' tall on erect, branching stems with ovate to lance-shaped, toothed, somewhat hairy, medium green foliage. Upward facing, bell-shaped (flaring at the mouth), violet-blue to deep purple flowers (1.5" long) appear mostly in terminal clusters atop the stems for a period of about 2-3 weeks in late spring to early summer. Clusters can have up to 15 flowers each, hence the common name of clustered bellflower.
No serious insect or disease problems. Slugs and snails can be an occasional problem. Plants may self-seed somewhat rapidly to the point of being weedy under ideal growing conditions.
This cultivar provides color and contrast to the perennial border or rock garden or naturalized area. Needs to be planted in groups for best effect.
