A plant genus consisting of more than 400 species, passion flower vine (Passiflora sp.) is a climbing plant originated in South America. Reaching up to 90 feet in length, this climber uses tendrils to climb trees, but the flowers are borne in lower level because many of its pollinators tend to be found in the lower storey. The flower of passion vine is unmistakable, and easily identified by the corona that consists of numerous thread-like spikes. Passion flower comes in various colours including blue, purple and red.
The spectacular passion flowers are borne singly, each with 5 petals and sepals. At the center of the flower is the stamen, the female organs, with three stigmas where the pollens land at the initial stage of fertilization. Just below them are the male organs or stamens. There are typically five stamens in each flower. Depending of species, passion vine flowers are pollinated by butterflies, bees, bats and birds.
