Tussilago farfara L.
Plant Family: Asteraceae
Coltsfoot grows wild over much of Europe. The name is derived from the horseshoe shaped leaves. It was so popular in Europe at one time that French pharmacists painted its flowers on their doorposts. It was brought to the American colonies from Europe. Before the plant flowers, it resembles butterbur enough that old herbals caution against confusing the two.
