Campanula americana is a native wildflower with blue-green leaves and very tall stems of violet-blue flowers from July to October. The 1" wide flowers have five petals, and they are flat, rather than bell-shaped like most campanula species. They attract hummingbirds and butterflies.
Campanula americana is a biennial that self sows prolifically to replace itself. Plant it at the back of the border or wildflower garden with other tall perennials and shrubs that won't be overwhelmed by it. I enjoy it with Chinese trumpet lilies, which bloom around the same time.
Campanula americana prefers average to moist soil and part sun to full shade. Also known as Tall Bellflower and Campanula americanum. Hardy in zones 3-8.
