A native of Europe, first collected in 1976 in moist ground at Marquette and in Eaton Co.; locally well established near Marquette. 

Cultivated as an ornamental for its striking foliage, blades of the reniform to orbicular, shallowly angular-lobed, finely toothed basal leaves are huge, often as broad as 3.5 dm and are recorded as 1 m on plants in Eaton Co. An update on the status of this species in Michigan is provided by Rotter (2018). A similar species, Petasites japonicus, is occasionally cultivated, both for the large leaves and as the Japanese vegetable fuki, and is known as an escape in Ontario. It differs from P. hybridus in its whitish flowers and unlobed leaves.
