How to Propagate a Passion Flower Vine

Overview

Native to South America, the passion flower vine, (Passiflora), is a fast-growing climber that you can train to wrap its tendrils around a trellis to beautify a patio or porch, or it can camouflage an unsightly fence or wall. In cold-weather climates, you can grow passion flower vine as a houseplant. The passion flower vine will produce showy blooms every summer in shades of pink, blue, purple, white or red, depending on the variety. The blooms will be followed by edible egg-shaped fruits, which are attractive but not especially flavorful. It isn't difficult to propagate a passion flower vine. Just take a stem cutting in late spring or early summer.

Step 1

Fill a 6-inch planting container with a potting mixture made of half coarse sand and half peat moss. Dampen the mixture by putting the planting container in a saucer filled with water. The potting mixture will absorb water through the drainage hole in the bottom of the container. Remove the container from the water as soon as the potting mixture is damp clear through.

Step 2

Cut a 4- to 5-inch stem from a healthy passion flower vine, making the cut with a sharp knife or razor blade just below a leaf. The cutting should have at least three or four leaves. Strip the leaves from the bottom 1/2 to 2/3 of the leaf, leaving the uppermost leaves intact.

Step 3

Put a small amount of powdered rooting hormone in a small plastic bag. Dip the cut end of the passion flower stem in the rooting hormone so about an inch of the vine is covered with powder. Shake the excess powder back into the plastic bag.

Step 4

Make a hole in the potting mixture with a tool, such as a small stick or a pencil, and plant the passion flower vine in the hole. Tamp the soil lightly around the vine with your fingers.

Step 5

Cover the planting container with a resealable bag, which will act as a miniature greenhouse. Place the container in warm room where it will be exposed to indirect sunlight. A sunny window or hot sunlight will be too warm and can scorch the passion flower vine. The plastic will keep the environment damp for several days, but you should check the potting mixture often. If the potting mixture is dry to the touch, open the bag and mist inside.

Step 6

Watch for the passion flower vine to root in two to three weeks. Rooting is indicated by the appearance of new growth. You can also tug lightly on a vine, and if it resists, it has rooted. Once the vine has rooted, remove the plastic bag and move the container into a sunny window. If you intend to plant the passion flower vine outdoors, leave it inside to mature until the following spring.
