Butterbur - Petasites hybridus
Short to tall, hairy, patch forming plant that grows each year from a creeping rhizome. The leaves are large, roughly heart-shaped and emerging from the rhizome, they are grey-hairy beneath, appearing after the flowers. The male and female flowers are on separate plants (dioecious). Flowerheads are pale reddish violet unscented and borne in cone shaped panicles.
The Giant Butterbur (Petasites japonicus subsp giganteus) is occasionally naturalised. It has larger leaves, dentate rather than lobed, and the bracts under the flower heads are much larger; the flowerheads are hemispherical unlike Butterbur's cylindrical heads.
White Buttterbur (Petasites albus) has also been recorded in VC55 in the past
