so what are Jerusalem Artichokes

Jerusalem Artichoke (Helianthus Tuberosus ) is a perennial plant which grows to a height of 10 ft. The flowers look like small Sunflowers, and are grown for their edible root.

Many names are attributed to this genus including :-

  • Sunchokes
  • Sunroots
  • Earth Apples
  • Girasole
  • Jerusalem Artichoke

They originate from the North American continent where they were first cultivated by Native Americans long before Europeans inhabited the continent.

 Jerusalem Artichokes are not from Jerusalem and they’re not Artichokes.

Why the confusing name then?

This member of the sunflower family played a vital role in feeding the Native Americans and then once the Europeans arrived they too were interested in this vital root.

The “Jerusalem” bit is due to  Italian immigrants in America calling them “Girasole”- Italian for Sunflower. which over the years evolved into Jerusalem.

Artichoke because the French explorer Samuel De Champlain sent samples back to France and described them as similar in flavour to Artichokes.

Over the years Jerusalem Artichokes became popular in Europe whilst losing favour in America, although popularity is increasing in the USA in recent times.
