Description

Campanula glomerata, or Clustered Bellflower, is a herbaceous, clumping, perennial that grows well in average, medium moisture, well-drained soil in full sun or part shade. Most species of Campanula perform best in areas with cool nights, but Clustered Bellflower will grow in the southeast in moist soils and partial shade. If your summer climate is cool, site the plant in full sun; however, if the summer climate is hot, you will have more success with a site in partial shade. Regardless of the site, the plant requires regular moisture.

The plant is quite showy, with densely packed clusters of light blue flowers. To encourage flower blooms, promptly deadhead, or remove, spent flower stems. Bellflower naturalizes by rhizomes and can be invasive, particularly in moist soils. To keep the plant growing vigorously while preventing it from spreading indiscriminately, divide the clumps in the fall every 3 to 5 years. Plants naturalize by rhizomes and occasionally, small colonies of plants are produced from the long rhizomes, particularly in moist soils

Members of the genus Campanula support the Plasterer bee (Colletes brevicornis). The Bellflower is also known to tolerate deer.
