Arctium minus
Species of flowering plant
Arctium minus, commonly known as lesser burdock,[2] little burdock, louse-bur, common burdock,[3] button-bur, cuckoo-button,[3] or wild rhubarb,[4] is a biennial plant. This plant is native to Europe,[5] but has become introduced elsewhere such as Australia, North and South America, and other places.[6][7][8][9]
Lesser burdock produces purple flowers in its second year of growth, from July to October. Outer bracts end in hooks that are like hook-and-loop. After the flower head dries, the hooked bracts will attach to humans and animals to transport the entire seedhead.[10]
