Bellflowers are among the most popular of perennials. This Clustered Bellflower selection has a mid-sized habit. It forms a mound of coarse green leaves low to the ground, with taller stems that bear large clusters of rich deep violet-blue to purple flowers in early summer. Superb for cutting. Quickly spreads to form a small patch, but easily managed by dividing plants in spring or fall. Combines beautifully with anything gold or yellow, for contrast. Worth trying in containers.
