Is marjoram the same as oregano?

Marjoram and oregano are related herbs but are not the same. Both belong to the same plant family, Lamiaceae, and have similar flavors, but marjoram (Origanum majorana) is generally milder and sweeter, while oregano (Origanum vulgare) has a stronger, more pungent taste. They are often used in different culinary contexts, with oregano commonly found in Italian and Mediterranean dishes, and marjoram more prevalent in French and Middle Eastern cuisines. Despite their differences, they can sometimes be used interchangeably in recipes, depending on the desired flavor profile.
