The Cotton Seeds are a crop from the Natura mod. Cotton Seeds can be obtained by bashing tall grass, or breaking existing Cotton plants. Cotton Seeds, though can be found on grass, must be planted on tilled farmland. Cotton plants are used to grow Cotton, which can be harvested by "using" the block, when there are white circles on it. Breaking the Cotton plant while these bulbs are purple will result in more Cotton Seeds. A 3x3 pattern of Cotton Seeds in a Crafting Table will result in a Cotton Seed Bag, which plants Cotton in a 3x3 area.
