This European wildflower occurs in lawns, roadsides, waste places, fence lines and river banks, reaching 30–100 cm (12–40 in) in height.
Campanula rapunculoides blooms from June to autumn, producing showy, bright blue-violet, drooping flowers with five deep lobes.
The flowers come in spike-like racemes on slightly curved flower stalks.
Creeping bellflower produces erect, unbranched, smooth or finely hairy stems.
Its basal leaves are heart-shaped and wider, becoming shorter and narrower toward the top.
Small seed capsules will follow the flower, containing many small, shiny, light brown seeds.
Campanula rapunculoides grows in any soil, in full sun and part shade.
As beautiful as they are, wildflowers are not garden ornamentals.
Creeping bellflower is one of those extremely vigorous wildflower species that will overwhelm less vigorous garden plants.
It spreads into adjacent areas by persistent underground rhizomes and taproot-shaped tubers as well as by its numerous, tinny seed. It is a very persistent plant, nearly impossible to eradicate it by digging or pulling the roots out because any small pieces of the roots will sprout into new plants.
It can be easily controlled though, when planted in containers and deadheading before the seed capsules form.
