''Symphyotrichum dumosum'', common name bushy aster or New York aster, is a plant species long known as ''Aster dumosus''. The genus ''Aster'' has been narrowed considerably in scope in recent years due to more information about the diversity in the group. ''Symphyotrichum dumosum'' is widespread across the eastern half of the United States from Texas to Florida to Maine to Wisconsin. It is also known from New Brunswick and Ontario, and is cultivated in other places.〔(Flora of North America v 20 p 514. )〕 ''Symphyotrichum dumosum'' is a perennial herb up to 100 cm (40 inches) tall. Heads are born in paniculiform arrays. Ray flowers are blue, pink, purple or white; disc flowers pale yellow, turning pink with age.〔G. L.
