Sub-category: Aster family
This is probably Connecticut's most common aster of shady places. Typically growing to heights between 30 to 90 cm, though some specimens may be up to 1.2 m tall. The species is distinguished by its flower heads that have yellow centers and white rays that are arranged in flat-topped corymbiform arrays, emerging in the late summer through fall. Other distinguishing characteristics include its serpentine stems and sharply serrated narrow heart-shaped leaves.
It occurs in the eastern United States, primarily in the Appalachian mountains. It often grows as a volunteer in gardens; a favorite location is the base of hedges.
