Now 'tis the time when, tall,
The long blue torches of the bellflower gleam
Among the trees; and, by the wooded stream,
In many a fragrant ball,
Blooms of the button-bush fall.
From "July" by Madison Cawein
Tall Bellflower is also known as American Bellflower.
The flowers are located along the single stem, at each leaf. They are a lovely blue with a white circle in the center, with 5 petals. The long style curves upward. Before opening, the flower buds have well-defined ridges.
