Dalmatian Bellflower

Campanula portenschlagiana

The best bellflower for trailing over stone walls, filling spaces between stepping stones, and accenting rock gardens. Charming bell-shaped purple flowers nearly hide the mounds of green, toothed foliage during the bloom period, lasting from spring to early summer; may bloom again in the fall. An herbaceous perennial.
