Anthemis tinctoria of Michigan Flora.

A Eurasian species, cultivated and occasionally escaped with garden debris or otherwise. Roadsides, refuse areas, railroads, vacant lots, fields, and shores. First collected in 1922 in Emmet Co.

The ray flowers are fertile, and retain their cheerful strong yellow color when dry.

Plants of Tanacetum bipinnatum subsp. huronense with a domed receptacle might be keyed here, but can easily be distinguished by lack of chaff on the receptacle and very short rays (less than 4 mm). Cota tinctoria has a chaffy receptacle and long rays.
