Passion fruit (Passiflora edulis) is a vine species of passion flower that is native to Brazil, Paraguay and northern Argentina, its common names include passionfruit and purple granadilla. The passion fruit is round to oval, either yellow or dark purple at maturity, with a soft to firm, juicy interior filled with numerous seeds. The fruit is both eaten and juiced, passion fruit juice is often added to other fruit juices to enhance the aroma.

Several distinct varieties of passion fruit with clearly differing exterior appearances exist. The bright yellow flavicarpa variety, also known as the Golden Passion Fruit, can grow up to the size of a grapefruit, has a smooth, glossy, light and airy rind. The dark purple edulis variety is smaller than a lemon, though it is less acidic than the yellow passion fruit, and has a richer aroma and flavour. Fresh passion fruit is high in beta carotene, potassium, and dietary fibre. Passion fruit juice is a good source of ascorbic acid (vitamin C), and good for people who have high blood pressure. Some research is showing that purple passion fruit peel may help with controlling asthma symptoms. The fruit contains Lycopene in the mature and immature pericarp.
