Sunchoke

Helianthus tuberosus

vegetable

The sunchoke, or Jerusalem artichoke, is a tall native sunflower grown for its knobby underground tubers, which have a sweet, nutty, water-chestnut crunch raw and a flavor like artichoke heart when cooked. The vigorous perennial plants reach six feet or more with small yellow blooms, and they are extremely easy to grow, spreading readily from any tuber left in the ground.

✅ Plant alongside

Good neighbors that attract beneficial insects or deter pests

• Corn — Matches its height so neither is shaded out
• Sunflowers — Similar tall, sturdy habit shares the bed
• Beans — Fix nitrogen and can climb the tall stalks
• Rhubarb — Another permanent-bed crop that tolerates its vigor

• Spreading and weediness

  Plant in a contained bed or barrier and dig thoroughly, since leftover tubers resprout

• Slugs →

  Trap and hand-pick after dark around young shoots

• Sclerotinia →

  Rotate and avoid waterlogged ground; remove infected stalks

🌾 Harvest & storage

Dig the tubers in fall after the first frosts, which improve their flavor by converting some of their inulin to sugar; harvest as needed through fall and, where the ground does not freeze solid, into winter and early spring. The tubers have thin skins and do not store long once dug, so leave them in the soil until you need them.

🥗 Nutrition & benefits

Sunchokes are a notable source of iron and potassium and store their carbohydrate as inulin rather than starch, a prebiotic fiber that feeds beneficial gut bacteria and has little effect on blood sugar, though it can cause gas in large amounts.
