Mint is a wonderful herb to have laying around, but its culinary uses are definitely limited. Because of its root structure, it can sometimes be an invasive plant. Once you grow mint in your garden, home, or farm, it may keep returning every year and may even take over areas that you intend for other plants.
I recommend that if you will be growing mint, that you grow it in a separate planter box so that it is limited to the planter itself and cannot spread to your surrounding garden. Keep the plant closer to the middle of the planter and do not let it flower (so that it cannot disperse its seeds). In fact, keep it away from your garden in general.
