Campanula Olympica

Campanula Olympica

A compact, long-blooming bellflower valued for its rich violet-blue flowers, tidy clumping habit, and excellent border performance. Nodding, bell-shaped blooms appear in early to mid-summer, held just above a neat mound of green foliage, offering refined color without aggressive spread.

Growth is well-behaved and clump-forming, making it an easy, reliable choice for smaller gardens and mixed perennial plantings.
