Stachys affinis, the Chinese artichoke, chorogi, knotroot, artichoke betony, or crosne, is an herbaceous perennial plant of the family Lamiaceae. Its tuber can be grown as a root vegetable. While the plant is easy to grow, the tubers are small, convoluted, and indented, so they are difficult to cook. The thin skin is of whitish-brown or ivory-white. The flesh underneath, under proper cultivation, is white and tender. Chinese poets compare it to jade beads.^{[citation needed]} It is in season generally commencing with October.
The flavor of the tubers is delicate, and they can be prepared similarly to Jerusalem artichokes in cooking. It is used as a vegetable, in salad compositions, but more so as a garnish. It has a nutty, artichoke-like flavor.
In China, the Chinese artichoke is used primarily for pickling. Its tuber is a part of Osechi cooked for celebrating Japanese New Year. Dyed red by leaves of red shiso after pickled, it is called Chorogi. In French cuisine, its cooked tuber is often served alongside dishes named japonaise or Japanese-styled.
