Where to find buttonbush. E. Lucy Braun, in The Woody Plants of Ohio (1961, 1989; The Ohio State University Press) tell us that that butonbush is “Very wide-ranging, throughout the eastern half of the United States, extending westward across the prairies in sloughs, and in the southwestern states and Mexico; reaching its largest size (occasionally 12-16 m.) in river-bottom swamps of southern Arkansas and eastern Texas. In Ohio, usually 1.5-2 (-3) m. in height.”
