Arctic sweet coltsfoot (Petasites frigidus var. palmatus, Asteraceae) is a cold-hardy herbaceous perennial that is native to northern Asia, Europe, and North America. It prefers moist soil and shade and can often be found near streams and wet forests throughout its range.
In early spring individuals first appear by growing a stalk of clustered flowers that can range from white to pink in color. Broad palmate leaves soon follow, reaching considerable size (nearly 8 inches/20 cm across) through spring and summer.
This plants goes by a number of other common names, including western coltsfoot, palmate coltsfoot, arctic butterbur, and palmate butterbur.
