General Information
Oregano is a shrub-like herb with multiple-branched stems, growing either upright or in a creeping manner, depending on the variety. It can grow as tall as three feet in height. The leaves are narrow and pinnate, or arrow-shaped, and have a soft, fuzzy texture. They grow in pairs, well-spaced out along tender stems. As the plant grows, the more mature stems become woody at the base. In the late summer, small white flowers bloom from the flower spikes (bracts) at the top of the stems. Typically, Oregano is harvested just before the flowers bloom when the flavor and aroma is at its peak. Oregano is said to have a ‘balsamic’ flavor; a combination of mint (a closely related herb), thyme, and rosemary. The taste is strong and somewhat bitter.
History
Oregano is native to the Mediterranean and the region stretching east towards Asia. The botanical name Origanum vulgare comes from the Greek oros for “mountain” and ganos for “joy,” named for its favorite growth habit – the warm, dry mountainsides of Greece. Oregano was cultivated in France since the Middle Ages and is a major component of Mediterranean cuisine. The herb was unknown to Americans until the 20th century when soldiers returning from World War I brought Oregano back from Italy. There are many plants that are referred to as “Oregano” because they contain high amounts of carvacrol, which is responsible for the flavor profile indicative of Oregano. It is estimated that there are over forty different species and countless hybrids of Oregano due to the wide variability of the species and its ability to cross-pollinate very easily.
