Rhizomes, wild rice is actually a mutation of plant rhizomes.

Water bamboo shoots are also known as high melons, wild bamboo shoots, wild rice hands, wild bamboo shoots, and high bamboo shoots. It is a perennial herbaceous plant of the Gramineae family. It is divided into double-season wild rice and single-season wild rice (or divided into one-ripe wild rice and two-ripe wild rice). Double-season wild rice (two-ripe wild rice) has higher yield and better quality. The ancients called wild rice "wild rice". Before the Tang Dynasty, wild rice was cultivated as a food crop. Its seeds are called wild rice or wild rice, and it is one of the "six grains" (steamed rice, millet, millet, beam, wheat, and wild rice). Later, people discovered that some wild rice plants did not ear due to infection with smut fungus, and the plants showed no signs of disease. The stems continued to expand and gradually formed spindle-shaped fleshy stems. This is the wild rice root that is eaten today. In this way, people use smut fungus to prevent wild rice from flowering and bearing fruit, and propagate this diseased and deformed plant as a vegetable. Can be used as medicine. In the world, only China and Vietnam cultivate wild rice as a vegetable. Wild rice is known as one of the three good things in Baizhuangzi, Xintai, Shandong (the three good things are wild rice, spring buds, and wild duck eggs), and it has been passed down since ancient times. It mostly grows in the Yangtze River and lake areas and is suitable for growing in fresh water.
