Spearmint is a type of mint plant that grows in most of the temperate regions of the world, areas that have hot summers and cool or cold winters. Spearmint yields an oil used in making perfumes, medicine, chewing gum, candies, and mint jelly or sauce. It has smooth, erect stems 1 to 2 feet (30 to 61 centimeters) high, topped with spikes of lavender or white flowers. Most spearmints in the United States grow in Idaho, Indiana, Michigan, Washington, and Wisconsin.
