Passiflora edulis forma flavicarpa flower

Passiflora edulis forma flavicarpa or Yellow Passion Fruit is a vigorous vine with gorgeous flowers.

This is a species that is not commonly available in supermarkets, the taste being more acidic than that of Passiflora edulis forma edulis.

As they are more resistant to soil diseases and pests, they are used for grafting of fo. edulis in fruit production.

Seeds can be harvested easily from a purchased fruit. But seeds will produce variations as it hybridizes readily. The only way to produce offspring with the same characteristics, is by cuttings.

It is not hardy and must be treated as an orangery plant: grow in a pot and overwinter indoors, protected from frost.


Passiflora edulis f. flavicarpa 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 are spherical to oblong, are 5-12 cm in diameter and 4-8 cm wide, with a thick, leathery, yellow skin. They contain many shiny brown seeds which measure 3-4 mm. The taste is more acidic than that of fo. edulis.


The fruits are used in drinks, candies, sorbets and desserts.

Used as rootstock for grafting fo. edulis.

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


2-3 times a year


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.

Sowing instructions:

  • remove seeds from the fruit
  • remove vesicles by rubbing the seeds in a sieve or roll between two sheets of kitchen paper
  • you can sow the seeds immediately in a pot with soil, purchased seeds should be soaked in water for 1-2 days at 20-25 °C
  • moisten the soil
  • place the pot in a plastic bag or propagator
  • temperature: 20-25 °C
  • germination time: 2-3 weeks to several months
  • seeds lose their germination power after about 1 year
