It blooms from July to September.
This is the species whose roots are eaten by the omnivorous
European peasant.
One of the few native campanulas, the TALL BELLFLOWER (C.
Americana), waves long, slender wands studded with blue or
sometimes whitish flowers high above the ground of moist thickets
and woods throughout the eastern half of this country, but rarely
near the sea. Doubtless the salt air, which intensifies the color
of so many flowers, would brighten its rather slatey blue. The
corolla, which is flat, round, about an inch across, and deeply
cleft into five pointed petals, has the effect of a miniature
pinwheel in motion. Mature flowers have the style elongated, bent
downward, then curved upward, that the stigmas may certainly be
in the way of the visiting insect pollen-laden from an earlier
bloomer, and be cross-fertilized. The larger bees, its
benefactors, which visit it for nectar, touch only the upper side
of the style, on which they must alight; but the anthers waste
pollen by shedding it on all sides.
