If you look out into any field in Middle Tennessee and see a bunch of yellow flowers, more than likely, this is it. Southern Ragwort (Senecio anonymus) is also known as Appalachian Ragwort and was used by Native Americans to treat heart trouble and to prevent pregnancy. Caution should be used because this plant contains toxins that have been shown to increase blood pressure and cause uterine contractions and liver damage. Also, it may possibly contain cancer-causing compounds.
This wildflower is a member of the Aster family (Asteraceae).
