Tall Bellflower, American Bellflower - Campanulastrum americanum


Family: Campanulaceae - Bellflower family Genus Common Name: Bellflower Native Status: Native
Campanulastrum americanum - Tall Bellflower, American Bellflower. This species is perhaps more widely known as Campanula americana which would place it in the genus containing Southern Harebell (C. Divaricata) and Bluebell Bellflower (Campanula rotundifolia.) However, the Campanula species have distinctly bell-shaped flowers, which is not the case with Campanulastrum americanum, which has relatively flat flowers. That would have been one of the characteristics that resulted in creation of a new genus for American (aka Tall) Bellflower - Campanulastrum which has this single species in it.

The plant is found in most of the eastern half of the United States except for the New England states, New Jersey, and Delaware.

Tall Bellflower appears to have 5 blue petals, but those are actually lobes of the corolla rather than real petals. The long style extends from the violet ovary, and is tipped with a 3-lobed stigma.
