Cotton Seeds are a type of seed added by Natura that grow into Cotton plants. They can be found by breaking tall grass like wheat seeds. While cotton plants maybe found in the wild on grass, cotton seeds must be planted in tilled soil, and prefer high light levels. When fully grown, the cotton may be harvested with a right click, and a new supply of cotton will grow back on the same plant.
It is possible to farm Cotton Seeds by breaking a cotton plant early, when they are in the "purple bulb" stage, which will yield 1-3 seeds instead of the usually seeds and cotton.
