About Boltonia asteroides (L.) L'Hér.
Boltonia asteroides (L.) L'Hér., commonly known as white doll's daisy, false chamomile, or false aster, is a perennial plant species native to the United States and Canada. Its primary range covers the Mississippi Valley and Great Plains, extending from Saskatchewan south to Texas and Florida, with isolated populations occurring in the eastern United States. Records of this species in New England, New York, and the Pacific Northwest are believed to represent introductions. Boltonia asteroides is a robust perennial that grows between 16 inches (40 cm) and 78 inches (198 cm) tall. It spreads via stolons, which are horizontal stems that grow along the ground surface. The plant produces many daisy-like flower heads, with white or lavender ray florets and yellow disc florets. Because of its attractive flowers, it is sometimes grown as an ornamental plant. Three varieties are recognized: Boltonia asteroides var. asteroides, which occurs in coastal regions; Boltonia asteroides var. latisquama (A.Gray) Cronquist, native to the Great Plains and Mississippi Valley; and Boltonia asteroides var. recognita (Fernald & Griscom) Cronquist, native to the Great Plains, Mississippi Valley, Ohio Valley, and Canadian Prairie Provinces, and introduced in New England and the Pacific Northwest.
