Takinogawa Arctinum lappa
Greater Burdock is a biennial plant, rather tall, reaching as much as 3 m (10 ft). 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 1 m (3 ft 3 in) deep.
