Native to North America, the Jerusalem artichoke ( Helianthus tuberosus ) first became a staple food for Indigenous peoples before being introduced to European gardens. The 'White Ordinary' variety, with its pale tubers, perpetuates this long-standing presence in our gardens.

In the garden, it forms tall, upright stems with ample green foliage, reminiscent of a small field of wild sunflowers. In late summer, its yellow flowers brighten the corner of the vegetable garden and attract a host of pollinators. Beneath this airy presence lies a veritable reservoir of life: fleshy, irregular tubers, harvested in autumn and early winter, which contribute to the garden's cycle by nourishing both the soil and the table.

It is a reliable, hardy plant that returns year after year where the soil is welcoming. It naturally finds its place in a harmonious garden, in the background of cultivated beds, like a living, edible hedge that one learns to guide rather than completely control.

  • Growing climate: Cool season
  • Sowing difficulty level: Easy
  • Care required: Occasional
  • Growth: Summer growth

Note: Very hardy and vigorous plant, which can become invasive if tubers are left in the ground.

Jerusalem artichoke tubers can be eaten raw or cooked. Raw, thinly sliced ​​or grated, they add a juicy crunch and an artichoke-like flavor to salads. Cooked (roasted, sautéed, mashed, in soups, or in gratins), they become tender and slightly sweet.

They can be combined with potatoes, carrots or squash in stews. Traditionally, they were harvested late in the season, sometimes under the snow, as a supplementary vegetable when pantry supplies were running low.

The tubers do not keep well in the open air: it is best to store them in the ground, in a trench filled with slightly damp sand, or in the refrigerator in a perforated bag for a short period. Their high inulin content makes them a particular food for some sensitive individuals (sometimes due to a fermentable effect), which suggests introducing them gradually into the diet.
