Senecio

The genus Senecio of the daisy family (Asteraceae) includes ragworts and groundsels. The flowerheads are normally rayed, completely yellow, and the flowers are borne in branched clusters. Though of late it has been reviewed and split up, it still contains a vast number of species of extremely wide form including leaf succulents, stem and tuber succulents, annuals, perennials, aquatic forms, climbers, shrubs and small trees.
