Also known as "Giant granadilla" Passiflora Quadrangular is a big passion vine native to tropical America with the biggest fruits of the Passiflora genus.

Large leaves to 25 cm (10”) long and big colourful showy fragrant flowers up to 12 cm (5”) wide. Large heavy fruits up to 30 cm (12”) long that turns yellow when fully ripe. The un-ripe fruit when green can be boiled and used as a vegetable.

An ornamental tropical vine that in tropical regions can reaches 45 metres (150 ft) long although in cooler regions or in containers it is not so vigorous. 

Thrives in warm humid tropics, but avoid flooding. Suitable in most temperate climates. Protect from freezing temperatures. 

Although seed can be sown most of the year in Australia seed is generally best sown in spring, avoid the coldest and hottest months of the year. The optimum germination temperature for germination is around 25-30°C

To assist in the uptake of moisture for germination to occur seed is best soaked in warm water for 24 hours prior to sowing.

Warm water soak is recommended for this species.

  1. Place the seed in a container with warm water (around 25°C) and allow to soak 24hrs.
  2. Sow seed on surface of a porous seed raising mix. The seed will lodge in the the pores of the mix once watered.
  3. Cover lightly with the seed raising mix. Do not bury the seed to deeply.
  4. Water with fine mist spray to avoid disturbance of the seed.
  5. Place in a warm shaded or semi shaded position to avoid dying out.
  6. Keep warm & moist, avoid drying out or waterlogging the growing mix.
  7. Germination should occur in 30-60 days @ 25-30°C

General note: Seeds of many plants are dormant and require specific conditions or pre-treatment for germination.
Do not be too hasty to discard seed that does not germinate, seeds will often lay dormant until the conditions are similar to their natural requirements for germination to occur. Containers put to one side will often surprise long after they were discarded.
