Notes: Giant Butterbur produces blooms in late winter, before any foliage appears. It is cultivated in gardens and has become a local garden escape. Petasites japonicus is naturalized in Great Britain, the Netherlands and Denmark. It is considered an exotic as it is native to Japan. Giant Butterbur produces a network of pencil-sized rhizomes that spread in all directions from the original plant. It begins to colonize an extensive area after its second or third year.
