serbian bellflower campanula poscharskyana
Serbian bellflower is a low-growing campanula that grows well in almost any garden soil except poorly drained clay. Tuck it between the stones of a rock wall or rock garden. The roots will reach deep into the wall to get moisture. Serbian bellflower can also be planted along the edge of a flower bed. As long as it has full sun to part shade it’s happy.
True to its name, ‘Blue Waterfall’, above, has profuse blooms that give the illusion of water cascading from the plant. After it’s finished flowering in summer, clip it back by about half and it blooms again in autumn.
TYPE Perennial SIZE 4 to 6 inches tall by 18 to 24 inches wide BLOOM Late spring to fall if deadheaded LIGHT Full sun to part shade SOIL Well-drained PESTS None serious HARDINESS Cold: USDA zones 4 to 7 Heat: AHS zones 7 to 1
