Serbian bellflower

Serbian bellflower (Campanula poscharskyana, Campanulaceae) is a semi-evergreen trailing perennial from the Dinaric Alps of southeastern Europe (Croatia). It reaches up to 1 foot tall with a spreading, trailing habit. Lavender-blue star-shaped flowers bloom prolifically from May to June, creating a cascading display on walls, rock gardens, and border edges.

Serbian bellflower grows in sun to part shade with moderate water needs, hardy in Zones 3 to 8. It is deer-resistant and requires low maintenance. The plant spreads steadily and works well as a groundcover, in rock crevices, and draped over walls or containers. No significant pest or disease issues are documented. No named cultivars are in the profile.
