Ripe fruits may drop naturally; collect from ground or pick when they yield slightly to pressure. Cut with pruning shears leaving short stem. Best harvested in morning.

Fun Facts
- 🌱 The intricate crown-like corona of filaments in the flower's center inspired its name—'passion' refers to the Passion of Christ, with the flower's structures representing elements of the crucifixion.
- 🌱 Passion vine butterflies (Heliconius) have a remarkable symbiotic relationship with passion vines: they feed on the leaves as caterpillars, and some species even place pheromone markers on plants they've already laid eggs on to prevent other females from laying there, reducing sibling competition.
- 🌱 The fruit flavor is described as a complex blend of tropical notes with a slightly tart, seedy interior that releases intense aromatic compounds when broken open; one passion fruit can flavor a large pitcher of juice.
