Mint is grown for its aromatic and flavorful leaves. Oval and serrated, the leaves of mint are indented with veins and come to a point. They impart a fresh clean scent and a strong mint flavor with sweet overtones. Leaves are commonly bright to dark green in color but some varieties can be purple, gray-green or even pale yellow. The cool taste and sensation mint imparts is a result of the naturally occurring compound, menthol contained in the herb.
