European Coltsfoot

Tussilago farfara


Family Name: Asteraceae
Class: B
Other Names:

coltsfoot, bullsfoot, coughwort, butterbur, horsehoof, foalswort, fieldhove, English tobacco, hallfoot

 Why is it a noxious weed?

It thrives in open to shaded disturbed habitats, forming extensive colonies. It is a known weed in European agricultural systems, where it is difficult to control, as well as native plant communities. In Washington, European coltsfoot has established in riparian areas after knotweed (Polygonum species) control. European coltsfoot is known to contain small amounts of toxic pyrrolizidine alkaloids.
