Petasites japonicus, also known as butterbur, giant butterbur, great butterbur and sweet-coltsfoot, is an herbaceous perennial plant in the family Asteraceae.[3] It is native to China, Japan, Korea and Sakhalin and introduced in Europe and North America. It was introduced to southern British Columbia in Canada by Japanese migrants.[4][5]
It is dioecious, with male and female flowers produced on separate individuals. Occasionally, morphologically hermaphroditic (but functionally sterile) flowers exist.[6]
