Through the centuries burdock has variously been called clotbur, cuckoo button, flapper-bags, gypsy's rhizome, happy major, and pig's rhubarb. Its official name derives from a combination of the Greek arktos ("Bear"),for its furry fruits, and the Latin lappare ("to grab"), for it's tenacious burrs.
