Campanula Blue Waterfall

Blue Waterfall Bellflower

A cascading bellflower valued for its rich violet-blue flowers, trailing habit, and long bloom season. Abundant star-shaped, bell-like blooms appear from late spring into summer, spilling gracefully over edges and containers to create a waterfall effect of color.

Growth is low and spreading, making it especially effective for softening hard edges and adding movement to plantings.
