Campanula Poscharskyana 'Blue Waterfall' PPAF

Serbian Bellflower

A vigorous, trailing groundcover perennial known for its cascading habit and heavy bloom. ‘Blue Waterfall’ produces masses of star-shaped violet-blue flowers that spill over walls, edges, and containers from late spring through summer, often with repeat bloom into early fall. Small, bright green foliage forms a dense mat that can be semi-evergreen in mild winters.
