Campanula 'Twister Bell' Bellflower
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, unique, blue and white bi-colour flower clusters in late spring into 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. If desired, trim plants back to 4 inches after flowering, to rejuvenate the foliage and tidy up for the remainder of the season.
