Regardless of what you choose to call the Passiflora incarnata , These 3 inch diameter flowers are very unique and beautiful. They begin blooming in July and continue until frost. The vines can easily grow up to 15 feet in a season. Grow it on a fence or trellis, or simply allow it to scramble over your shrubs and trees. The fruit produced by this plant is an oval berry, a little larger than a chicken egg.
Passion fruit is edible, but seedy.
It can be used to make jelly, but its best usage may come from being a food source for several species of butterfly and their larvae. The top growth is killed back by frost, but 'pops' back to life in the Spring. Passion flowers are easy to grow. They need partial to full sun, and will adapt themselves to most well-drained soils. During the growing season, the soil should be kept evenly moist, to ensure good flowering and growth.
