sweet marjoram

Sweet marjoram (Origanum majorana) is usually grown in herb gardens and tends to grow upright, unlike pot marjoram. It has delicate leaves with a sweet, slightly citrusy flavor and is hardy in USDA Zones 9 to 11, though it will not withstand a freeze and is often grown as an annual. It is cultivated for its aromatic leaves, used fresh or dried as seasoning in many regional cuisines.
