Other info. - This species is most common in the southern half of Missouri but is found scattered throughout the state. The plant is very common along roadsides and waste ground in its range. This is an easy species to identify in the field because of its thin leaves and big yellow flower heads.
H. amarum is toxic to humans and livestock and is seldom eaten. If it is ingested by milk producing cows, the milk will be bitter and unpalatable. Because of this, the species is sometimes called "Bitterweed."
