Marjoram (
Origanum majorana, syn.
Majorana hortensis Moench,
Majorana majorana (L.) H. Karst) is a somewhat cold-sensitive
perennial herb or undershrub with sweet
pine and
citrus flavors. In some Middle Eastern countries, marjoram is synonymous with
oregano, and there the names
sweet marjoram and
knotted marjoram are used to distinguish it from other plants of the genus
Origanum. It is also called
pot marjoram, although this name is also used for other cultivated species of
Origanum.
