The passion vine is a vigorous plant that grows in length 20 feet each year and requires a strong support structure. Passion vine is native to South America and is hardy to plant in USDA hardiness zones 9 through 11, where the winters are mild. The plant produces long evergreen leaves and attractive, fragrant flowers. Passion vine plants live for five to seven years but can be propagated by taking woody stem cuttings in late spring.
Cut from your passion vine 3- to 4-inch-long stem sections that include three to four bud nodes. Make each cut just below a leaf with a sharp knife.
Mix even quantities of course sand, sterile peat moss and perlite to create a rooting medium for the stem cuttings. Add water to lightly dampen the medium.
Fill a rooting tray with the rooting medium.
Dip the lower cut end of each passion vine stem in powdered rooting hormone. Gently tap the stem to remove excess powder.
Stick the stem into the rooting medium. Space the stem cuttings approximately 2 inches apart so the stems and leaves do not touch.
Mist the medium and cuttings with water to increase the moisture level, and place a plastic bag over the tray to hold humidity around your passion vine cuttings during the rooting process.
Place the tray in a warm location that offers indirect light.
Monitor the moisture level to prevent the medium and cuttings from drying out. Mist the tray with water as needed.
Gently pull on your passion vine cuttings after four weeks to see if there is resistance from root development. They should be ready to transplant after 90 days of growth.
Transplant your passion vine cuttings to individual 4-inch containers once the roots are a minimum of 1 inch in length.
Set your passion vine containers in a protected area outdoors or continue to grow them in a bright location indoors. Do not plant your cuttings in the ground until the second year of growth.
