Synonyms: Campanula americana
USDA Symbol: caam18
USDA Native Status: Native to U.S.
A 3-4 ft., erect plant with leafy stems. The upper portion of the stem is lined with showy, lavender-blue, five-petaled flowers. Radially symmetrical, light blue to violet flowers borne singly or in clusters in axils of upper leaves and forming an elongated, spike-like cluster.
In spite of the common name and the genus name, derived from the Latin campana (bell), the flowers of this species are usually flat, not bell-shaped as are many others in this family. Tall Bellflower was formerly included in the genus Campanula.
