Filago is a genus of plants in the sunflower family, native to Europe, Asia, and North Africa. They are sometimes called cottonroses or cudweeds.[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 genus Logfia.
Description[]
They bear woolly, cottony heads of flowers. They have narrow strap-shaped untoothed leaves. 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.
