Jerusalem artichoke

Helianthus tuberosus
Rate and Comment
Jerusalem artichoke

This North American native is a relative of the sunflower and as you watch it grow, you'll see how. From mid- to late summer the plant produces yellow daisy flowers on tall stalks, but the edible part is the sweet, nutty, knobby tubers produced underground. If you haven't grown it before, it's a fun and fascinating plant to try.

Use tubers sliced, raw to add crunch to salads. Or cook them and use similar to potatoes. The plant spreads from tubers left in the soil and can become weedy.

Harvest Tips


Dig the tubers any time in fall after the soil has cooled. For sweetest flavor, wait until frost to dig. Harvest the largest tubers for eating and leave others to form next year's crop.
