Marjoram (Origanum majorana, Lamiaceae) is a cold-sensitive perennial herb or undershrub with sweet pine and citrus flavors. It is also called Sweet Marjoram or Knotted Marjoram and Majorana hortensis.

The name marjoram (Old French majorane, Medieval Latin majorana) does not directly derive from the Latin word maior (major).^[1]

Marjoram is cultivated for its aromatic leaves, either green or dry, for culinary purposes; the tops are cut as the plants begin to flower and are dried slowly in the shade. It is often used in herb combinations such as Herbes de Provence and Za'atar.

Oregano (Origanum vulgare, sometimes listed with Marjoram as Origanum majorana) is also called Wild Marjoram. It is a perennial common in southern Europe in dry copses and on hedge-banks, with many stout stems 30-80 cm high, bearing short-stalked somewhat ovate leaves and clusters of purple flowers. It has a stronger flavor and a more penetrating quality.

Pot Marjoram or Cretan Oregano (Origanum onites) has similar uses to marjoram.
