White Butterbur
White Butterbur (Petasites albus) flowers early in the year, generally between February and May. The flowers are white and spiked, and dominate damp areas beside rivers. When flowering, the leaves are small; however, they can reach a width of up to 30cm after the plant has finished flowering. Visually, the leaves are similar to those of a rhubarb plant, with a slightly more heart-like shape. The leaves grow close to the ground, which created a dense carpet that covers the ground.
