Campanula glomerata (Clustered Bellflower)

Clustered Bellflower, Bellflower, Danesblood (Campanula Glomerata)


Vigorous, charming and eye-catching, Campanula glomerata (Clustered Bellflower) is a useful perennial that brings early color and contrast to the garden. It features bouquets of eye-catching, violet-blue to white, upward facing, bell-shaped flowers, held in dense clusters. They sit atop sturdy leafy stems above basal rosettes of heart-shaped to oval green leaves. These clusters can have up to 15 flowers, therefore the common name of Clustered Bellflower. Blooming for 2-3 weeks from late spring to early summer, this spreading perennial does well in most soils.

  • Easy to grow, virtually disease and pest free, this low care perennial is also deer and rabbit resistant and adored by hummingbirds, butterflies and bees.
  • Grows in sturdy clumps, up to 6-24 in. tall (15-60 cm) and 12-36 in. wide (30-00 cm), depending on cultivars. This plant has a tendency to spread rapidly in rich soils.
  • Thrives in full sun or part shade, in average, medium, well-drained soils. Prefers part shade in warmer climates. Needs regular moisture!
  • Ideal for beds, borders, cottage gardens, rock gardens or containers. Campanula glomerata makes excellent cut flowers that last up to 2 weeks in a vase!
  • Cut back after flowering, both to prevent self-seeding and to encourage a second flush of flowers.
  • Easily divided in spring or fall.
  • Propagate by division in spring or autumn or take basal cuttings in spring
