General Information

Passiflora bryonioides is a clump-forming, herbaceous perennial plant producing annual, climbing stems 50 - 200cm long from a thickened woody rotstock. The stems attach themselves to the surrounding vegetation by means of tendrils[].
The plant is harvested from the wild for local use as a food.

Cultivation Details

Passiflora bryonioides is found from the semi-arid, subtropical climate of Arizona, south to the moist tropics of southern Mexico. Not a very cold hardy plant, when dormant it can tolerate short periods with temperatures falling to around -8°c[].
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 tolerates disturbance well, often climbing inside shrubs to emerge at their tops, especially in grazed areas; in
rangeland it is a plant of hedgerows[].

Edible Uses

Fruit - raw[]. The juicy, watery arils of the fruit are prized by children and are sometimes also eaten as a thirst-quencher by adults[]. The pale green or light yellowish green, ovoid or ellipsoid fruit is 35 - 45mm long (including a 2 - 9mm long stipe) and 20 - 25mm in diameter[]. The translucent, whitish to yellowish white, fleshy arils are 11 - 15mm long, gelatinous in texture with a sweet, somewhat fruity-scented aroma[].

Medicinal

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[].

Other Uses

None known

Propagation

Seed - best sown as soon as it is ripe along with the pulp which will help break down the seed coat and speed up germination[]. Stored seed should be soaked for 24 hours in warm water and germination time can be reduced if the seed is then mixed with the juice of a fresh passion fruit (of any species)[]. Even so, it can take 12 months for stored seed to germinate[]. Place the seed tray in a shady position, maintaining a temperature around 19 - 24°c[]. Prick the seedlings out into individual containers as soon as they are large enough to handle and plant out when large enough[].
Cuttings of young shoots, taken at the nodes. The cuttings root best in a neutral to slightly acid compost, but 100% sharp sand also produces good results[].
Cuttings of fully mature wood taken at a node. They can take 3 months[].
Layering. Very easy[].
Air layering.
