The Eastern groundsel (Senecio vernalis) belongs to Asteraceae (the Aster family). It is an annual herb that is distributed from Europe to western Asia and the Caucasus. It grows in sunny meadows and along roadsides and is about 50 cm tall. The leaves are narrowly elliptic, pinnately deeply lobed, and alternate. From March to August, yellow flower heads, about 1.5 cm in diameter, appear in panicles at the top of the stem. The flowers are followed by seeds with white pappus, which are spread by the wind.
