Jerusalem artichoke

Helianthus tuberosus

Check your plant’s identity

Does the label say Helianthus tuberosus, Jerusalem artichoke or sunchoke? Tubers sold as Jerusalem artichoke for eating count too. Annual sunflower (Helianthus annuus), other perennial sunflowers and globe artichoke are different plants. If there is no label or it's unclear, choose I'm not sure; the reference picture does not confirm your plant.

Important precautions

The tubers are eaten as a vegetable; large amounts may cause wind. Pet safety is unknown. Tubers left in soil can spread. In Spain this species is listed as invasive: live plants and material capable of surviving or reproducing are generally subject to possession, transport and trade prohibitions. Limited exceptions exist for certain previously acquired plants confined to gardens, with no propagation, transfer or trade. The applicable historic date and food-tuber treatment are not resolved here. Ask the environmental authority before acquiring, planting or sharing it; this guide is not a permit.
