This species is native to the temperate regions of the old world, from Scandinavia to the Mediterranean, and from the British Isles through Russia, and the Middle East to China and Japan, including India. It is naturalized almost everywhere and is usually found in disturbed areas, especially in soil rich in nitrogen. It is commonly cultivated in Japan where it gives its name to a particular construction technique, burdock piling.
Greater burdock was used during the Middle Ages as a vegetable, but now it is rarely used, with the exception of Japan where it is called gobō (牛蒡 or ゴボウ), Taiwan (牛蒡), Korea where it is called ueong (우엉), Italy, Brazil and Portugal, where it is known as bardana or "garduna". Plants are cultivated for their slender roots, which can grow about 1 meter long and 2 cm across.
The root is very crisp and has a sweet, mild, and pungent flavor with a little muddy harshness that can be reduced by soaking julienned/shredded roots in water for five to ten minutes. The harshness shows excellent harmonization with pork in miso soup (tonjiru) and takikomi gohan (a Japanese-style pilaf).
