Japanese Butterbur belongs to the family of the Butterbur and can, like the White Butterbur, be counted as a stinzenplant. As the name implies, this species is native to Japan. In the beginning of the 19th century this plant came to Europe and planted in historical landscape gardens. The species also likes moist, nutrient-rich soil and can propagate via its rhizomes. The plante starts to flower in spring before the leaves arrive, in March/ April. The bloom is clearly later than the flowering of the white butterbur. The flower colour is yellowish white and the flowers are surrounded by green sepals. The flowers are visited by bees and bumblebees.
