The Jerusalem artichoke (Helianthus tuberosus), also called sunroot, sunchoke, or earth apple, is a species of sunflower native to eastern North America. Despite its name, the Jerusalem artichoke has no relation to Jerusalem nor is it a type of artichoke. The plant is cultivated for its tuber, which is edible and can be used in many ways, similar to potatoes. The Hebrew translation for Jerusalem artichoke is פרח השמש הקרפד (Prach HaShames HaKrapad). In French, it is known as topinambour, and in German, it is called Topinambur or Erdbirne (literally "earth pear"). The tuber of the Jerusalem artichoke is rich in inulin, a polysaccharide that is a fraction of the sweetness of sucrose. This makes it a suitable food for diabetics. The plant is also notable for its hardiness and ability to thrive in various soil conditions, making it a popular choice for gardeners and farmers alike.
