Passiflora ianthina Mast.
Tacsonia umbilicata Griseb.
Common Name: Locosti
Passiflora umbilicata is an evergreen climbing shrub, producing stems up to 5 metres long[
]. These stems scramble over the ground, or clamber into the surrounding vegetation, supporting themselves by means of coiling tendrils.
The fruit is gathered from the wild for local use, and the plant is sometimes grown as an ornamental[
South-western S. America - Argentina and Bolivia.
Grows in the mountains; at elevations from 2,500 - 3,000 metres[
Passiflora umbilicata succeeds in cooler climates than most members of this genus, growing in warm, essentially frost-free temperate areas as well as the subtropics and at moderate elevations in the tropics[
]. Plants require a temperature no lower than around 16°c when they are flowering in order to ensure fruit set[
Requires a humus-rich, moist but well-drained soil and a position in dappled shade where it can grow up towards the sun[
]. Prefers a circumneutral soil, disliking very acid or very alkaline conditions[
]. Passiflora species tend to flower and fruit more freely when grown in soils of only moderate fertility[
Plants are very tolerant of pruning and can be cut back to ground level if required to rejuvenate the plant[
]. Plants in this genus are notably resistant to honey fungus[
Very fast growing[
Fruit - raw or cooked[
]. The pulp surrounding the seeds is eaten. The yellowish, ovoid fruit is around 60 - 70mm long and 40mm wide[
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[
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, but there is usually a high percentage[
Layering. Very easy[
