The purple passion fruit plant originated in subtropical South America, and is native to an area stretching from southern Brazil to northern Argentina (Morton). Although the origin of the yellow passion fruit is not clear, it is believed to have also originated in the Amazon region of Brazil. Neither variety was well documented before the arrival of Europeans, but it is thought that these fruits were part of the native diet.
Since the 19th century, the purple passion fruit has spread worldwide and has become an important commercial crop in countries such as Costa Rica. Additionally, the passion fruit vine has also become native and grows wild in places like Hawaii and India. The purple passion fruit has since become a popular fruit in the United States as well.
As for the yellow passion fruit, it is less tolerant to cold and requires tropical growing conditions. It has gained some interest in Australia as a commercial crop and has been received with much enthusiasm in Venezuela.
The passion fruit vine can grow in a variety of soil environments. The vine itself is strong, woody, and can climb up to 15 feet long. It has three lobes, shiny green leaves, and unique flowers that are purple and white in color (Morton). Depending on the species, the flowers bloom at different times of the day. Generally, the yellow passion fruit vine produces brighter flowers than the purple variety.
