Senecio jacobaea– Common Ragwort
Other common name: Stinking willie
Genus: Jacobaea is not usually a significant problem in gardens, but its poisonous qualities can make it a serious weed of paddocks and gardens backing onto fields grazed by horses or cattle.
Details: Ragwort is a tall erect plant to 90cm, bearing large flat-topped clusters of yellow daisy-like flowers from July to October. It has finely divided leaves with a basal rosette of deeply-cut, toothed leaves. Common Ragwort is usually a biennial but damage to the base of the plant can make the plant behave like a perennial as new rosettes are formed.
