Dalmatian Bellflower

Campanula portenschlagiana (C. muralis) is an attractive, low-growing shrub with heart-shaped green leaves and bell-shaped, blue flowers on short stems that appear in spring and summer. Dalmatian Bellflower's dense habit makes it an excellent choice for small-scale areas, rock gardens, in between stepping stones, trailing over raised beds or walls, and borders. 

This herbaceous perennial grows best in evenly moist, well-drained soil in USDA zones 5-7. Evergreen in frost-free climates. In California, Campanula portenschlagiana grows well in full sun in cool, coastal climates, but needs shade for the hot afternoons in arid, inland gardens. For a longer flowering period, remove spent blooms. Prune for a tidy look when the flowering period is over.
