Mint plants are mainly aromatic perennials and they possess erect, branching stems and oblong to ovate or lanceolate leaves arranged in opposing pairs on the stems. The leaves are often covered in tiny hairs and have a serrated margin.
Once established mint requires little aftercare. Harvest mint leaves before the flowers develop and use them fresh, dried or frozen. Cut back the old stems in autumn and repot container-grown plants annually in spring.
