Campanula, Serbian Bell Flower

Campanula poscharskyana, commonly called Serbian Bellflower, is a short, mounding ground cover with an easy, undemanding habit. Creating a stream of lavender blue, the 1-inch-diameter star-shaped blossoms bloom reliably from late spring to early fall. The foliage remains evergreen in mild winters and needs to be sheared only once in a while to keep its appearance tidy. Perennial that prefers full sun to light shade.
