Easily grown in average, medium moisture, well-drained soil in full sun to part shade. Thrives in sandy/gritty soils with sharp drainage. Prefers part shade in hot summer climates. Performs best with regular moisture. Does not do well in climates where nighttime temperatures consistently remain above 70°F. Spreads by creeping rootstocks, but is not considered invasive, although it may be difficult to eradicate from a garden area once established. May be grown from seed. Clumps may be divided in spring.

Noteworthy Characteristics

Campanula kemulariae, commonly called campanula or bellflower, is a vigorous, low-growing, clumping perennial which typically rises to 4-8” tall, but spreads over time by creeping rootstocks to form an attractive ground cover to 12-24” wide. It is native to stony/rocky areas of the Transcaucasus. Bright green basal leaves form a 2-4” tall mound topped in May-June by abundant drooping spikes of broadly-campanulate (open bell-shaped), nodding, lavender-blue flowers (each to 1” long). Freely-branched, often decumbent, flowering stems grow to 12” long. Small, leathery, cordate-ovate, shiny green basal leaves have long petioles and doubly serrate margins. Synonymous with Campanula raddeana.

Genus name comes from the Latin campana meaning bell in reference to the bell-shaped flowers.


No serious insect or disease problems. Snails and slugs are occasional visitors.
