Passion fruit is grown primarily in South America. Production of the fruit became widespread in countries such as Colombia and Venezuela during the mid-1950s, eventually spreading to Ecuador as well, according to iTi Tropicals. These regions are the main areas exporting passion fruit to the Western world.
Passion fruit was originally believed to be native to Brazil and quickly became to be a favorite of 16th century Spanish explorers. They called it "Flor de las cinco llagas," or "flower of the five wounds," because of its brilliant purple buds. Since then, the fruit has spread to nearly all tropical locations. It was introduced to Hawaii in 1880 in home gardens, but it was found growing in the wild by 1930.
