Campanula americana, the American bellflower, is a tall bellflower native to eastern North America from the Great Lakes region south to Florida and from the Dakotas east to New York.
 This native plant is an annual or biennial from 2-6' tall.
 Its flowers are light blue to violet and are usually arranged in elongated clusters.
 It is an unusual bellflower in that its flowers are usually flat and not bell-shaped.
 It has a varying life-history with seeds germinating in the fall producing annual plants and spring-germinating seeds producing biennial plants.
 It is generally insect-pollinated, and does not usually self-pollinate.

 The nutlets usually come in clusters of four.
 These plants are found mainly in western North America.

 The genus name "Eucrypta" means "well-hidden", which refers to the seeds being "hidden" in the small green bristled fruits.

 These are small, weedy-looking annual plants with sticky, aromatic green foliage.
 The leaves are strongly lobed and look somewhat like fern fronds.
