Symphyotrichum dumosum, common names rice button aster[2] or bushy aster,[3] 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.[4]

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.[5]
