Life Cycle of an Incense Passion Flower Vine


The incense passion flower (Passiflora 'Incense') is a fast-growing flowering and fruit-bearing vine. The vine grows 10 to 20 feet in the summer season and dies back during the winter months. It is a hybrid that derives from plants native to South America and the southeast portion of the United States.


Separate the flesh of the fruit from the pod to harvest seeds. Allow several days for the seeds to dry in a shaded area. According to Passiflora Online, a passion vine seed planted in spring may not germinate until late summer or fall. It may even sit dormant until early the next spring.


As the passion vine sprout reaches the surface of the ground, it continues to grow upward toward the light. At this time the roots rapidly grow into the soil to absorb nutrients and minerals. According to Plant-Care, passion vine roots are shallow and can grow in many different soil types, but require exceptional drainage. As the leaves begin to grow and unfold, the plant manufactures nutrients by means of photosynthesis.


At maturity, the vine begins to form buds. The buds quickly develop into vibrant purple and white flowers. Water vines regularly to keep them flowering continually throughout the summer.


According to Trade Winds Fruit, incense passion flowers cannot pollinate themselves. To set fruit, the passion vine needs pollinators such as wind, bees, butterflies or human gardeners' hand pollination. The fruit is 1 to 3 inches long, oval, yellow and edible. Ripe fruits that drop to the ground will decompose, allowing the seeds to germinate naturally in the earth below.


The incense passion flower is a perennial vine that can live for three or more years. A healthy vine will die back in the winter when temperatures reach 32 degrees Fahrenheit. Regrowth begins in spring from roots or from mature woody stems.
