Passiflora foetida, commonly known as stinking passionflower or wild passionfruit, is a climbing vine in the Passifloraceae family. Native to the Americas but now widespread throughout the tropics, it is easily recognized by its delicate, filament-like bracts that encase its small fruits. The plant produces attractive white to pinkish flowers and edible, sweet-tart orange fruits. Traditionally used in herbal medicine, Passiflora foetida has been valued for its calming, anti-inflammatory, and antimicrobial properties.
