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

I found this species in La Porte County, where it covered an acre in very sandy soil in a yard and adjacent nursery. Peattie reported it as escaped in the Calumet District. The plant is used in medicine and cultivated in gardens, especially by people who still grow their own medicinal herbs.
