Growing Passiflora From Seed


The Passiflora edulis Sims, commonly known as the passion fruit, is grown for both fruit and ornamental purposes. Its glossy, trilobed leaves and colorful blossoms add beauty to a landscape while its fruit is sweet and juicy. If you have access to ripe passion fruit, collect the seeds and plant them to start your own Passiflora collection.

Step 1

Harvest the seeds from a ripe passion fruit. Depending on the variety, the fruit may have a dark purple or yellow exterior and feel slightly soft when pressed. Cut it open and scoop out the black seeds inside. Empty the seeds in a glass of water. Stir it vigorously with a spoon to rinse the seeds.

Step 2

Remove the seeds from the water and spread them on a plate or similar flat surface. Allow the seeds to dry for 24 to 48 hours.

Step 3

Rub the exterior of the seeds with fine sandpaper until the seeds have a scratched, grooved exterior. This hastens the germination time for the seeds by allowing water to better penetrate the seed coating, according to Purdue University in Indiana.

Step 4

Fill a quart-sized pot with potting soil. If you don't have potting soil on hand, combine equal parts of garden loam, compost or peat moss and sand or vermiculite.

Step 5

Plant the passion fruit seeds, burying two seeds per pot. Purdue University recommends burying them approximately 1/2 inch below the surface of the potting soil.

Step 6

Water the pot twice a day or as required to keep the soil surface moist. The passion fruit seeds will germinate within one to three weeks, according to the University of Florida. Pull out one of the two seedlings once they're a couple inches tall, leaving behind the seedling that's tallest and strongest.

Step 7

Transplant the seedling outdoors once it reaches 10 inches tall, advises the University of Florida. Select a garden site that receives full sun. Dig a hole that's the size of the current pot and move the passion fruit seedling from its pot into the hole. Fill in the hole's sides with dirt. If you're growing more than one plant, the University of Florida suggests separating them by 15 feet.

Tips and Warnings

  • Don't store passion fruit seeds after harvesting them, as they have a poor shelf life and their germination rate will fall quickly, according to Purdue University.
