Stachys affinis - Stachys affinis the Chinese artichoke chorogi knotroot artichoke betony or crosne is a perennial herbaceous plant of the family Lamiaceae. Its rhizome can be grown as a root vegetable. While the plant is easy to grow the tubers are small convoluted and indented so they are considered very tedious if not difficult to clean properly. The thin skin ranges from a pale beige to ivory-white colour. The flesh underneath under proper cultivation is white and tender.
