Botanists have discovered that the origin of Tahitian vanilla (Vanilla tahitensis), an orchid that when pollinated yields the most delectable vanilla bean on the planet, actually had its origins in the Mayan forests of Mexico and Guatemala. Whats interesting about this finding is that the Tahitian vanilla orchid is found only in cultivation and not in the wild.

Using DNA and ethno-historic analysis, Pesach Lubinsky, a postdoctoral researcher and Norman Ellstrand, a professor of genetics in UC Riverside’s Department of Botany and Plant Sciences, appear to have traced Tahitian vanilla back to its evolutionary beginning as a pre-Columbian Maya cultivar. Modern day Tahitian vanilla appears to be a hybrid between V. planifolia, a species cultivated for commercial vanilla that is primarily grown in Madagascar and Indonesia, and the never cultivated V. odorata both of which grow in the tropical forests of Central America.

The research team theorized that the Mayan people created forest gardens and introduced different types of species including wild cacao and vanilla from the surrounding region. Species that had previously been geographically separated were then able to hybridize simply because they were in the same location. Eventually French sailors introduced vanilla to Tahiti from cuttings of plants growing in the Philippines that had arrived there via the Spanish trading ships that sailed between Manila and Acapulco, Mexico.
