The Chinese artichoke or crone is an unusual small tuberous vegetable, actually a rhizome with a flavour similar to Jerusalem artichoke and a texture like water chestnuts. Hedge nettle. Stachys. The neutral flavor renders the easy-to-grow root particularly suitable for mixing with legumes. Run under a strong stream of water to clean, parboil briefly and toss in salads or with other prepared vegetables and seasonings. Easy to establish in the garden and difficult to weed out once planted.
