How to Plant Passion Flowers


The passion flower, also known as passion vine, can be an evergreen, deciduous or semi-evergreen vine, depending on how cold your climate is. Most varieties are indigenous to South America. They require full sun and grow to about 20 to 30 feet. Flowers can reach widths of 3 to 4 inches and come in many different colors, including light yellow green, salmon, pink, maroon and white.

Step 1

Decided if you want to plant your passion flower from seed or buy one already established. To germinate passion flower seeds, place the seeds in a bowl filled with warm water and let them soak for 24 hours before planting.

Step 2

Fill pots 3/4 of the way full with sterilized potting mix. Place the seeds 1/2 inch deep in the soil. Until the seeds germinate, maintain a temperature of 75 to 80 degrees F and keep the seedlings in a bright, sun-filled location. Germination can take 12 to 36 weeks. Keep the seedlings moist but not soggy, check them every few days and water once the soil is dried out.

Step 3

Choose a sunny location with ample drainage for your seedlings. They can be transplanted once they reach 2 to 3 inches in height and all danger of frost is past. Passion flowers need space to grow and climb. A trellis or a wired area will let your vine grow and provide ample support.

Step 4

Dig a hole approximately two times the width of the root ball with a shovel or small trowel. The depth of the hole should slightly deeper then the root ball. Clear out any rocks, weeds or roots in the hole that could interfere with the growth of your plant.

Step 5

Remove the plant gently from the pot. Hold your hand around the base of the plant, inside the pot, and turn the pot upside down. With your trowel, tap the edge of the pot until you see the pot start to slide off.

Step 1

Position your passion flower in the hole, making sure the plant is standing erect. Then partially fill the hole with soil, until it's about halfway filled. Fill the hole up with water, allowing it to settle back down into the soil. Gently firm the soil around the plant and fill the remainder of the hole.

Step 2

Water well after making a small berm of dirt around the plant, which allows water to soak down to the plant's roots. During the summer, and until your passion flower slower is fully established, water it thoroughly every week.

Step 3

Fertilize with a high potash fertilizer, preferably a liquid variety to prevent burn. Mulch is necessary if winter temperatures drop below 45 to 50 degrees F. Place mulch about 2 to 3 inches deep, and 3 feet in diameter around the plant.
