Arctium lappa, commonly called greater burdock, gobō,edible burdock, lappa, or beggar's buttons, is a biennial plant of the Arctium (burdock) genus in the Asteraceae family, cultivated in gardens for its root used as a vegetable. It is an invasive weed of high-nitrogen soils. Greater Burdock is rather tall, reaching as much as 9 feet (2.7 m). It has large, alternating, cordiform leaves that have a long petiole and are pubescent on the underside.
The flowers are purple and grouped in globular capitula, united in clusters. They appear in mid-summer, from July to September. The capitula are surrounded by an involucre made out of many bracts, each curving to form a hook, allowing them to be carried long distances on the fur of animals. The fruits are achenes; they are long, compressed, with short pappuses. The fleshy tap-root can grow up to 3 feet (0.91 m) deep.
