About Boltonia diffusa Elliott
Boltonia diffusa Elliott, commonly known as smallhead doll's daisy, is a North American plant species in the Asteraceae family. It is native to the United States, growing primarily along the Gulf of Mexico coast from Texas to Florida, as well as in the lower Mississippi Valley from Louisiana to Illinois. Additional populations are found in the eastern United States as far north as Virginia. This species is a small perennial herb that rarely grows taller than 20 cm (8 inches). It spreads via stolons, which are horizontal stems that grow along the ground surface. It produces numerous daisy-like flower heads, with white or lavender ray florets and yellow disc florets. Two varieties are recognized: Boltonia diffusa var. diffusa, found in coastal regions and the Mississippi Valley, and Boltonia diffusa var. interior Fernald & Griscom, found in the Mississippi Valley.
