Passiflora quadrangularis seeds grow into the giant granadilla — a vigorous climber native to the wet tropical biome from Colombia to Brazil. Described by Linnaeus. The epithet quadrangularis means 'four-angled' (from Latin quadrangulus), referring to the distinctive four-winged or four-angled green stems — one of the most instantly recognisable features of the species. The giant granadilla produces the largest fruits of any cultivated Passiflora: up to 30 cm long and 12 cm wide, with a thick spongy rind and sweet aromatic seeds. The immature fruit rind and roots are used medicinally (sedative, narcotic in excess — use with caution). Widely cultivated in lowland tropics globally. Medicine, poison, food, environmental uses. Family Passifloraceae.Full sun; moist, fertile, well-drained soils; warm wet tropical conditions. Very vigorous climber to 15 m or more. Giant fruits. CAUTION: rind and roots have sedative/narcotic properties — do not consume in excess. 'Quadrangularis' = four-angled (four-winged stems); L.
