Butterbur

Petasites hybridus

Fond of moist ground, Butterbur is a pink, tassled wildflower can often be found carpeting riversides and damp ditches.

With so many small flowers packed densely together, Butterbur is very popular with bees. It is a great source of nectar early in the year, when wildflowers are still rather sparse.

How to spot it

Flower spikes appear before the leaves and have tiny pale pink flowers arranged down stems which are 10-40cm tall. The leaves are very large, sometimes almost 1 meter wide and are downy-grey underneath.

Best time to spot it

The best time to see Butterbur is in spring, throughout March, April and May.
