American Bellflower, Tall Bellflower, Campanula americana, Campanula americana var. illinoensis
Native to North America, Campanulastrum americanum (American Bellflower) is an upright annual or biennial with tall flower stems clad with rough, toothed, lance-shaped green leaves. In summer, the upper portion of the stem is studded with showy, flat, star-shaped, lavender-blue flowers, 1 in. across (2.5 cm). Attractive to hummingbirds, each delicate blossom features a petal tube that elongates with age and a white ring at the throat. The flowers are borne singly or in clusters in the axils of the upper leaves. Charming and eye-catching, they will persist longer if deadheaded. Depending on when germination occurs, this plant is either an annual of a biennial. It produces foliage in the first year and flowers in the second year. American Bellflower is a lovely addition to a woodland garden where it will self-seed readily, without becoming a nuisance, and keep a charming presence.
