Passiflora edulis forma edulis or purple granadilla is a vigorous vine with gorgeous flowers.
This is the species that is most commonly for sale in supermarkets: dark purple fruits, sometimes wrinkled, spherical, with a diameter of about 5 cm.
Seeds can be harvested easily from a purchased fruit. There are a hundred seeds in each fruit, which is more than enough to play with, and they germinate fairly quickly and easily.
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. edulis is a vine whose stems can grow to over 8 m long. The stems are green, round and smooth. They climb any support with tendrils.
The leaves have serrated edges and are dark green, lobed to (often not lobed in young plants), shiny and 5-25 cm wide. The petiole is 3-4 cm long.
The flower stalks measure 2-6 cm long. The flowers are 5-8 cm in diameter. Sepals are white, oblong, up to 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 pink to purple in the first half and white and tortuous in the second half. Fo. edulis is self-pollinating, unlike Passiflora edulis fo. flavicarpa, and therefore forms fruit on its own.
The fruits vary in color, shape and size depending on cultivar. They are spherical, are 4-5 cm in diameter, with a thick, leathery, dark purple skin. They contain many shiny black seeds which measure 3-4 mm. The fruits have a fresh but tangy flavor.
The fruits are used in drinks, candies, sorbets and desserts.

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.

- 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
