In 1934 I found this hawkweed in the sandy commons on the south side of Simonton Lake in Elkhart County. In 1935 I found it in a sandy, waste field and in an adjoining open woodland on the north side of Weber Lake in Steuben County. It is an obnoxious weed in the eastern states and, unfortunately, it is now cultivated as an ornamental plant in Indiana. It will doubtless soon escape in many parts of the state if it has not already done so. Usually called Devil's-paint-brush.
