Passiflora edulis, commonly known as passion fruit, is a vine species of passion flower native to southern Brazil through Paraguay and northern Argentina. It is cultivated commercially in tropical and subtropical areas for its sweet, seedy fruit. The fruit is a pepo, a type of berry, 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, the juice often added to other fruit juices to enhance aroma. The fruit produced is entirely fleshy (making it botanically a berry), and is spherical to ovoid. The outside color of the berry ranges from dark-purple with fine white specks to light yellow. The fruit is 4–7.5 cm in diameter; purple fruits are smaller, weighing around 35 grams, while yellow fruits are closer to 80 grams. The smooth, leathery rind is 9–13 mm thick, including a thick layer of pith. Within the berry, there are typically 250 brown seeds, each 2.4 mm in length. Each seed is surrounded by a membranous sac filled with pulpy juice. The flavor of the juice is slightly acidic and musky. The passion fruit's flavor can be compared to the guava fruit.
