About Butterbur
Petasites hybridus, commonly known as butterbur, is a vigorous perennial plant, noted for its large basal leaves up to 1 meter in diameter that emerge after flowering. It is a native species to Europe and Asia, ideal for covering large, shaded, and moist areas, such as pond or stream banks, where it can create a spectacular visual impact with its lush foliage. Its pale pink to purplish flowers emerge in compact spikes in early spring, before the leaves fully develop.

Europe and temperate Asia
Care tips
This plant thrives in partial to full shade, requiring consistently moist soil rich in organic matter. Abundant watering is essential, especially during dry periods, as it does not tolerate drought; the soil should never completely dry out. A common mistake is underestimating its vigor and tendency to spread, so it's best planted in areas where its spread is not an issue or using barriers to contain it. It tolerates a wide range of soils, but prefers loamy and clayey types.
