From Flora of Indiana (1940) by Charles C. Deam This shrub grows in very sandy soil about Lake Michigan where it is more or less frequent. South of the lake it becomes very rare. In Fountain and Montgomery Counties a few specimens were found on the crests of wooded sandstone ridges. In slightly acid soil this species does well in cultivation. ......
