Vanilla is a spice derived from orchids of the genus Vanilla, primarily obtained from pods of the Mexican species, flat-leaved vanilla (V. planifolia). The word vanilla, derived from vainilla, the diminutive of the Spanish word vaina (vaina itself meaning a sheath or a pod), is translated simply as "little pod". Pre-Columbian Mesoamerican people cultivated the vine of the vanilla orchid, called tlīlxochitl by the Aztecs.
Pollination is required to make the plants produce the fruit from which the vanilla spice is obtained. In 1837, Belgian botanist Charles François Antoine Morren discovered this fact and pioneered a method of artificially pollinating the plant. The method proved financially unworkable and was not deployed commercially. In 1841, Edmond Albius, a 12-year-old slave who lived on the French island of Réunion in the Indian Ocean, discovered that the plant could be hand-pollinated. Hand-pollination allowed global cultivation of the plant. Noted French botanist and plant collector Jean Michel Claude Richard falsely claimed to have discovered the technique three or four years earlier. By the end of the 20th century, Albius was considered the true discoverer.
Three major species of vanilla currently are grown globally, all of which derive from a species originally found in Mesoamerica, including parts of modern-day Mexico. They are V. planifolia (syn. V. fragrans), grown on Madagascar, Réunion, and other tropical areas along the Indian Ocean; V. tahitensis, grown in the South Pacific; and V. pompona, found in the West Indies, Central America, and South America. The majority of the world's vanilla is the V. planifolia species, more commonly known as Bourbon vanilla (after the former name of Réunion, Île Bourbon) or Madagascar vanilla, which is produced in Madagascar and neighboring islands in the southwestern Indian Ocean, and in Indonesia. Madagascar’s and Indonesia’s cultivations produce two-thirds of the world's supply of vanilla.
Vanilla is the second-most expensive spice after saffron because growing the vanilla seed pods is labor-intensive. Nevertheless, vanilla is widely used in both commercial and domestic baking, perfume manufacture, and aromatherapy.
