Coreopsis grandiflora var. harveyana

From Flora of Indiana (1940) by Charles C. Deam

According to Nieuwland, this species is well established along the Lincoln Highway near South Bend and in a few other places in St. Joseph County. Doubtless it has been introduced from the west. The seed may have been scattered here along the highway by some sentimental, trans-continental tourists who acted upon the ill advice published in a magazine a few years ago. It was recommended that tourists should scatter seeds of conspicuous flowers along the roadsides from coast to coast and from the Gulf of Mexico northward. This produced a storm of indignation from botanists who knew that such a procedure would destroy the natural range of species. The species has also been found about 3 miles south of Fort Wayne in an open woods which has been used for years as a dump.
