Tussilago petasites


Tussilago means "cough-wort."
The name of the genus, Petasites, is derived from petasos, the Greek word for the felt hats worn by shepherds, and familiar to us in representations of Mercury, in reference to the large size of the leaves, which could be used as a head-covering. No other vegetation can live where these leaves grow, for they exclude light and air from all beneath, and where the plant abounds, it has been described as 'the most pernicious of all the weeds which this country produces.'
The name Butterbur is supposed to have been given it because formerly these large leaves were used to wrap butter in during hot weather. 'Lagwort' is an old name we sometimes find for it, in reference to the leaves delaying their appearance till after the flowers have faded, though once the leaf-shoots make a start, they grow with almost tropical luxuriance.
