Passiflora subpeltata is a large climbing plant with stems that can become more or less woody. It climbs into the surrounding vegetation, attaching itself by means of tendrils.
Passiflora species generally grow best in a sheltered, sunny position or in dappled shade. Most species are found in the wild in moist but well-drained soils, generally of a lighter texture, and will often flower and fruit more heavily if the soil fertility is low. They often develop deep roots and can be moderately tolerant of dry spells. Most Passiflora species prefer a neutral to slightly alkaline soil, growing best where the pH is around 6. 5 – 7.5.
The plant is often grown as an ornamental. It has escaped from cultivation in some areas outside its native range and is invading native habitats.
The yellow-green, ovoid to subglobose fruit is 25 – 40mm in diameter.
The leaves and roots of some, if not all, members of this genus contain a substance called ‘passiflorina’ which has similaritiesr to morphine and is an effective tranquilizer. We have no specific information for this species but many species are used in herbal infusions to calm the nerves and help bring about a restful sleep.
The leaves of many species are also considered to be anthelmintic, antihysteric and diaphoretic. They are used in Brazil to combat intermittent fevers, cutaneous inflammations, and erysipelas.
