Cotton bushes are the first (and so far only) non-food bearing crop. They yield cotton when harvested, and harvesting cotton does not destroy the bush; rather it reverts to an earlier stage of growth which then comes to maturity again. A single cotton bush can, in theory, yield an unlimited amount of cotton.
Cotton[]
Cotton can be turned into string, which in turn can be turned into cloth, making cotton crops an alternative to harvesting wool from sheep.
Seeds[]
Cotton seeds are sometimes obtained by destroying shrubs, or by destroying an immature cotton plant, they may also be obtained by combining Hybrid Wheat seeds with Orange Seeds
