What are the best species for edible fruits?
P. edulis and P. mollissima (banana passionflower) are the species grown commercially. However, these varieties prefer a more tropical climate and can be difficult to maintain in a North American garden.
P. incarnata, or more commonly known as the maypop, is a common source of fruit for the home gardener. Maypops are about the size of an egg and get their name from the popping sound they make when stepped on in the garden. Ripe maypops have a yellowish-light brown skin and consist of a sweet, slimy gel-like pulp inside that surrounds the seeds.
