Arctium lappa, commonly called greater burdock, beggar's buttons, thorny burr, or happy major is a Eurasian species of plants cultivated in gardens for its root. Greater burdock is a biennial plant, rather tall, reaching as much as 3 metres (10 feet). It has large, alternating, wavy-edged cordiform leaves that have a long petiole and are pubescent on the underside. The flowers are purple and grouped, 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 the mature fruits to be carried long distances on the fur of animals. The burdock could be confused with rhubarb, the leaves of which are toxic. Type: Hardy perennial herb Hardiness zones: 2-10 Height: 3m, 10' Location: Sun Seeds per packet: 100
