Pappermint is a species of mint native to much of Europe and Asia (Middle East, Himalayas, China etc.), and naturalized in parts of northern and western Africa, North America, and South America, as well as various oceanic islands. Spearmint grows well in nearly all temperate climates. Gardeners often grow it in pots or planters due to its invasive, spreading rhizomes. The plant prefers partial shade, but can flourish in full sun to mostly shade. Spearmint is best suited to loamy soils with abundant organic material. Spearmint leaves can be used fresh, dried, or frozen. They can also be preserved in salt, sugar, sugar syrup, alcohol, or oil. The leaves lose their aromatic appeal after the plant flowers. It can be dried by cutting just before, or right (at peak) as the flowers open, about one-half to three-quarters the way down the stalk (leaving smaller shoots room to grow).
