var.

, L.

Oregano or Pot Marjoram (Origanum vulgare) is a species of Origanum, native to Europe, the Mediterranean region and southern and central Asia. It is a perennial herb, growing to 20-80 cm tall, with opposite leaves 1-4 cm long. The flowers are purple, 3-4 mm long, produced in erect spikes. Its name derives from the Greek origanon.

Cultivation

The subspecies of oregano Origanum vulgare hirtum is an important culinary herb. It is particularly widely used in Greek and Italian cuisines. It is the leaves that are used in cooking, and the dried herb is often more flavourful than the fresh.^{[citation needed]}

It has an aromatic, warm and slightly bitter taste. It varies in intensity; good quality is so strong that it almost numbs the tongue, but the cultivars adapted to colder climates have often unsatisfactory flavour. The influence of climate, season and soil on the composition of the essential oil is greater than the difference between the various species.

The related species Origanum onites (Greece, Asia Minor) and O. heracleoticum (Italy, Balkan peninsula, West Asia) have similar flavours. A closely related plant is marjoram from Asia Minor, which, however, differs significantly in taste, because phenolic compounds are missing in its essential oil. Some breeds show a flavour intermediate between oregano and marjoram.

Other plants called oregano

Mexican oregano, Lippia graveolens (Verbenaceae) is closely related to lemon verbena. It is a highly studied herb that is said to be of some medical use and is common in curandera female shamanic practices in Mexico and the Southwestern United States. Mexican oregano has a very similar flavour to oregano, but is usually stronger. It is becoming more commonly sold outside of Mexico, especially in the United States. It is sometimes used as a substitute for epazote leaves; this substitution would not work the other way round.

Several other plants are also known as oregano in various parts of Mexico, including Poliomintha longiflora, Lippia berlandieri, and Plectranthus amboinicus (syn. Coleus aromaticus), also called Cuban oregano.
