There are currently three major cultivars of vanilla grown globally, all derived from a species originally found in Mesoamerica, including parts of modern day Mexico. The various subspecies are Vanilla 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 and South America. The majority of the world's vanilla that is produced is the V. planifolia variety, more commonly known as "Madagascar-Bourbon" vanilla, which is produced in a small region of the East African nation of Madagascar and in Indonesia.

Vanilla is the second most expensive spice after saffron, due the extensive labor required to grow the seed pods used in its manufacture. Despite the expense, it is highly valued for its flavor which author Frederic Rosengarten, Jr. described in The Book of Spices as "pure, spicy, and delicate" and its complex floral aroma depicted as a "peculiar bouquet." Regardless of its high cost, vanilla is widely used in both commercial and domestic baking, perfume manufacture and aroma therapy.

History

The first to cultivate vanilla were the Totonac people, who inhabit the Mazantla Valley on the Gulf Coast of Mexico in the present-day state of Veracruz. According to Totonac mythology, the tropical orchid was born when Princess Xanat, forbidden by her father from marrying a mortal, fled to the forest with her lover. The lovers were captured and beheaded. Where their blood touched the ground, the vine of the tropical orchid grew.

In the fifteenth century, Aztecs from the central highlands of Mexico conquered the Totonacs, and the conquerors soon developed a taste for the vanilla bean. They named the bean "tlilxochitl", or "black flower", after the mature bean, which shrivels and turns black shortly after it is picked. After they were subjected to the Aztecs the Totonacs paid their tribute by sending vanilla beans to the Aztec capital, Tenochtitlan.

Vanilla was completely unknown in the Old World before Columbus. Spanish explorers who arrived on the Gulf Coast of Mexico in the early sixteenth century gave vanilla its name. The Spanish and Portuguese sailors and explorers brought vanilla into Africa and Asia in the 16th century. They called it vainilla, or "little pod", The word vanilla entered the English language in the 1754, when the botanist Philip Miller wrote about the genus in his Gardener's Dictionary.
