Notes
'Caroline' clustered bellflower (Campanula glomerata 'Caroline') is a perennial for borders, cottage gardens, pollinator gardens, and rock gardens. It is hardy to USDA zone 3, or down to -40°F (-40°C). This plant likes full or part sun and average to moist soil of most types. Shell pink to lavender flowers open in early to late spring and again in early to late summer. Butterflies, hummingbirds, and bees visit the blooms. It is not a favorite of deer or rabbits, though hungry ones will eat almost anything.
Pairs well with Cytherea peony, Blonde Ambition blue grama, Nodding onion, and Rose.
