Mianhua (Cotton) in Dengzhou City
Cotton is the seed fiber of plants in the genus Gossypium of the mallow family. It is native to subtropical regions. The plant has a shrub-like form and can grow up to 6 meters tall in tropical areas, though it generally reaches 1 to 2 meters. Its flowers are milky white and turn deep red shortly after blooming before withering away, leaving behind small green capsules known as cotton bolls. Inside the bolls are cotton seeds, and the fine fibers grow from the seed coat, filling the interior of the boll. When the cotton bolls mature, they split open to reveal the soft fibers. These fibers are white to off-white, about 2 to 4 centimeters long, and contain approximately 87–90% cellulose. Countries with the highest cotton production include China, the United States, and India.
