Petasites hybridus (Marginal Aquatic)

The densely packed flowers of this British native provide a banquet for bumble bees early in the year before when few other flowers are available.  From March to May, before the leaves unfurl, Petasites hybridus produces clusters of pale pink, tassel-like flowers on sturdy, upright stems. The flowers are followed by large, umbrella-like, heart-shaped leaves that can span up to 1 meter in diameter and were once used to wrap pats of butter, earning it the common name of ‘butterbur’. These impressive leaves provide substantial ground cover and a hiding place for insects and small animals.  A native of riversides, damp ditches and meadows, Petasites hybridus thrives in reliably damp soils and bog gardens. Spreading via underground rhizomes, Butterbur can form dense colonies, making it an effective ground cover in damp areas where its spread can be controlled. A striking choice for damp areas in the larger garden, offering bold, jungle-like foliage plus significant benefits for wildlife. Ultimate height: 1-1.5m (3.2 to 4.9ft). Ultimate spread: 2.5m to 4m (8.2 to 13ft).
