Description

Campanula americana, or American Bellflower, is an annual or biennial wildflower native to moist open woods, moist meadows, streambanks and ditches in shady areas of eastern North America  It is best grown in rich, moist, well-drained soils in part shade. They will tolerate more sun in cooler summer climates but prefer afternoon shade where summer climates are hot. This bellflower will readily reseed itself in the garden and is good for naturalizing. It is a pollinator magnet: many species of bees, wasps, butterflies, and hummingbirds will visit and search for nectar and pollen.
