It is variously known as the '''woodland ragwort''',<ref>{{PLANTS|id=SESY|taxon=Senecio sylvaticus|accessdate=10 November 2015}}</ref> '''heath groundsel''',<ref name=BSBI07>{{BSBI 2007 |access-date=2014-10-17 }}</ref> or '''mountain [common groundsel](/source/Senecio_vulgaris)'''.<ref>{{Cite EB9|wstitle=Groundsel |volume=11 |page=221}}</ref> It is native to [Eurasia](/source/Eurasia), and it can be found in other places, including western and eastern sections of North America, as an [introduced species](/source/introduced_species) and an occasional roadside weed. It grows best in cool, wet areas. It is an annual herb producing a single erect stem up to 80 centimeters tall from a [taproot](/source/taproot). It is coated in short, curly hairs. The toothed, deeply lobed leaves are up to 12 centimeters long and borne on [petioles](/source/Petiole_(botany)). They are evenly distributed along the stem. The [inflorescence](/source/inflorescence) is a wide, spreading array of many [flower heads](/source/Head_(botany)), each lined with green- or black-tipped [phyllaries](/source/bract). The heads contain yellow disc florets and most have very tiny yellow ray florets as well.
