Ground pear or Jerusalem artichoke
Jerusalem artichoke appeared in Russia relatively recently, only 400 years ago. He came to us from North America, where it is still found in the wild. In Russia, it is only grown as a fodder, food and industrial crop. Better known as "earthen pear" and "Jerusalem artichoke". Sometimes, Jerusalem artichoke was confused with potatoes, considering one of the varieties.
Perennial herb. Refers to the type of tuberous plants of the genus Sunflower of the family Astrovye. Its height can reach two meters. It has a powerful root system on which tubers develop.
The chemical composition of Jerusalem artichoke is similar to that of potatoes. The nutritional properties and vitamin-mineral complex contained in an earthen pear are many times superior to those of vegetables. The sugar content in Jerusalem artichoke depends on the harvest time of the plant.
