Petasites albus
White butterbur is a vigorous, spreading perennial that thrives in moist, shaded spots such as stream banks, woodland edges, and bog gardens. Its large, bold leaves create striking ground cover in damp shade where few other plants perform well. Plant with adequate space as it spreads assertively via rhizomes and can colonize large areas over time.
