Passiflora edulis forma flavicarpa ‘Panam Red’ is a selection of Passiflora edulis forma flavicarpa with big dark red to purple fruit.
It is a selection developed in Australia where it is widely grown commercially. It has a good resistance to Fusarium.
Since it’s a selection and not a hybrid, it can be grown from seeds harvested from fruit.
It is only slightly frost resistant hardy and must be treated as an orangery plant: grow in a pot and overwinter indoors, protected from frost.
This is a very fast grower that can produce 100 flowers and fruit in one season.
Passiflora edulis fo. flavicarpa ‘Panama Red’ is a vine whose stems can grow to over 8 m long. The stems are brownish green and solid. They climb any support with tendrils.
The leaves have serrated edges and are darker green than those of fo. edulis, lobed to (often not lobed in young plants), shiny and 5-25 cm wide.
The flowers are 6-9 cm in diameter, a little bigger than those of fo. edulis. Sepals are white, oblong, up to 3,3 cm long and 1 cm wide. Petals are white, oblong, up to 3 cm long and 0.8 cm wide. The corona consists of four or five rows of filaments which are dark purple to black in the lower half and white and tortuous in the upper half. Fo. flavicarpa is not self-pollinating, unlike the fo. edulis, and therefore needs cross pollination to form fruit.
Fruit is dark red to purple with prominent lenticels, spherical to oblong, are 5-12 cm long and 4-8 cm wide, with a thick, leathery skin. They contain many shiny brown seeds which measure 3-4 mm. The taste is similar to of Passiflora edulis fo. edulis.
The fruits are eaten fresh or used in drinks, candies, sorbets and desserts.

Accommodates a wide range of soils
Keep moist, may sometimes be wet. It resists short periods of drought by dropping its leaves.
Prefers full sun but tolerates partial shade
Fertilize weekly with universal liquid fertilizer, all year
As flowers and fruit appear on new growth, vigorous pruning in autumn is recommended
Use a relatively small pot: a large pot promotes growth at the expense of flowering. In a small pot, the plant feels threatened and will be pushed to bloom.
Overwintering frost free, in a room with minimum 13 °C. When the temperature is about 15 °C and the danger of frost has passed, it can be brought outdoors again.
By seed and cuttings.
- use preferably fresh seeds
- scarify the seeds with sandpaper or sand
- soak the seeds in water at room temperature for 24h
- plant in potting soil, a 1 cm depth
- provide soil heating and switch the heating off at night so that the temperature fluctuates
- keep the substrate moist
- do not discard the seeds if they have not germinated after a few months, it can take more than 6 months
