How to Propagate Passion Flowers

Overview

The passion flower (Passiflora incarnate) grows on a hardy vine, and blooms from mid-summer to mid-fall. Also known as maypop, the vine produces small fruit which pop when stepped on. The passion-flower vine thrives in full sun and attracts bees and butterflies into the garden. The passion flower can be propagated by air-layering, root division and from seed. The passion flower is hardy to U.S. Department of Agriculture (USDA) Plant Hardiness Zones 6b to 10b.

Step 1

Mix one 2 tbsp. of household bleach with 6 tbsp. of water in a container. Remove the fleshy covering from the seeds by scrubbing them lightly under running water. Place the seeds in the bleach solution, seal the container and place in the refrigerator for 24 hours. The bleach will help kill any fungus that might be growing on the seed.

Step 2

Pour the seeding mix into the seeding tray to within 1/4 inch of the top of the tray. Soak the planting medium with water and allow the excess water to drain from the bottom of the tray.

Step 3

Sow the seeds 1/2 inch into the soil and cover with soil.

Step 4

Place the seeding tray on the heating mat, set to 75 degrees F.

Step 5

Check the soil daily to maintain moisture. If the soil begins to dry out, use the misting bottle, set on a fine spray, to mist the soil until it is moist but not soggy.

Step 6

Place the seedlings, when they have two sets of leaves, into individual planting pots filled with an equal mixture of peat moss and compost, watered well.
