Oregano is known botanically as Origanum vulgare and is called wild marjoram in many parts of Europe since it is closely related to the herb that we know as sweet marjoram. Its name is derived from the Greek words oros (mountain) and ganos (joy) since not only was it a symbol of happiness, but it made the hillsides on which it grew look beautiful. It is a small shrub with multi-branched stems covered with small grayish-green oval leaves and small white or pink flowers. In Mediterranean climates, oregano grows as a perennial plant, but in the harsher climates of North America, they grow as annuals. The warm, balsamic and aromatic flavor of oregano makes it the perfect addition to many different dishes, especially those of Mediterranean and Mexican cuisines.
