Ragwort is a European introduction. It grows abun- 
dantly in the east and locally as far west as Ontario. 
It is an erect plant eight inches to two feet or 
more in height, and may be smooth or more 
or less covered with woolly hairs. The root leaves are 
lyrate, while those on the stem are deeply pinnately dis- 
sected or divided into small lobes. The bright yellow 
flower-heads, about one-half inch across, contain both 
tubular and ray florets as in the daisy, and are arranged 
in a flat-topped cluster. The plant blooms in July and 
August and forms a very striking feature of the 
landscape.
