Campanula poscharskyana: Serbian Bellflower – Trailing Starry Blue Flowers for Walls

Campanula poscharskyana – Serbian Bellflower, Poscharsky's Bellflower

Campanula poscharskyana, the Serbian Bellflower, is a beloved, trailing perennial that forms a low mat of rounded, toothed leaves. From late spring into summer, it produces a profusion of star-shaped, lavender-blue flowers with a white eye on wiry, trailing stems. It blooms heavily and is perfect for cascading over walls, rock edges, and containers.

Serbian Bellflower thrives in partial shade to full sun (with moisture) and well-drained soil. It spreads moderately by rhizomes and self-sows gently. It is more heat-tolerant than many alpine campanulas. A classic, carefree plant for vertical accents and softening hardscapes. One of the most popular and reliable campanulas for garden use.
