Campanula Birch Hybrid

Birch Hybrid Bellflower

A compact, spreading bellflower valued for its lavender-blue blooms, long flowering season, and excellent groundcover performance. Star-shaped flowers appear in late spring and continue into summer, often reblooming with deadheading, creating a soft carpet of color above low, green foliage.

Growth is low and mat-forming, spreading gently to fill spaces without becoming aggressive.
