Filago is a genus of plants in the sunflower family, native from Europe and northern Africa to Mongolia, Nepal, and Macaronesia.

[2][3][4][5][6] The name cudweed comes from the fact that they were once used to feed cows that had lost the ability to chew the cud.

[7] Several species are sometimes treated as members of the genus Logfia.

The flower heads are small, gathered into dense, stalkless clusters.

The fruits have a hairy pappus,[8] or modified calyx, the part of an individual disk, ray or ligule floret surrounding the base of the corolla, in flower heads of the plant family Asteraceae.
