Ginger, also known as ginger, is a perennial herb. Native to North America, it was introduced to Europe in the17th century and then to China. It blooms in autumn and has small yellow flowers in the shape of chrysanthemums. In production, it is usually propagated by tuber. Its underground tubers are rich in fructose polymers such as starch and inulin, which can be eaten, cooked or cooked in porridge, pickled pickles, sun-dried Jerusalem artichoke, or used as raw materials for making starch and alcohol. Working feed can also be added to the aboveground stems.
