Stachys affinis, the Chinese artichoke, knotroot, artichoke betony, or crosne, is an herbaceous perennial plant of the family Lamiaceae. Although its edible tuber can be grown as a root vegetable, it is a rare sight in the garden. From a cultivation standpoint this is rather odd — the plant is easy to grow, requiring neither staking nor earthing-up. The reason that it is so unpopular is the nature of the tubers — small, convoluted and indented, so that it is the cook rather than the gardener or the family who finds this vegetable frustrating.

The flavour of the tubers is delicate and delicious — they can be treated as jerusalem artichokes in cooking.

In China, the Chinese artichoke is used primarily for pickling.
