Hieracium
Hieracium, is a large genus in the aster family, Asteraceae, that recently has been split into two genera , Hieracium and Pilosella. The differentiating factor is that the species now classified as Pilosella have smooth leaves and spread with runners. Species still classified as Hieracium can form seeds asexually, so the number of species isn't clear. They grow in dry grasslands in full sun.
