About this plant
Campanula portenschlagiana, commonly known as Dalmatian Bellflower, is a vigorous, spreading perennial prized for its profusion of star-shaped, violet-blue flowers. Blooming from late spring through summer, this plant creates a stunning display as its blooms cascade over walls, rock gardens, or fill gaps in borders. The bell-shaped flowers are particularly striking against the small, heart-shaped, bright green foliage, providing a dense, colorful ground cover.
Native to the rocky cliffs of the Dalmatian coast in Croatia, Campanula portenschlagiana is well-suited for rockeries, crevices, and alpine-style gardens, thriving in challenging, well-drained environments. Its ability to spread quickly and adapt to a variety of garden settings makes it a popular choice for those looking to add a burst of color and texture to sunny, dry areas. The plant's hardiness and long blooming period have made it a favorite in both traditional and modern gardens.

Design tip
Allow this spreading bellflower to soften the edges of stone walls, steps, or raised planters by letting it flow naturally over the sides. The cascading habit blurs hard architectural lines, creating a landscape that feels mature, inviting, and effortlessly connected.
