It is woody in warm winter climates but dies to the ground in cold winter climates. Care It grows in average-fertility, well-drained soils in full sun to part shade. Although this vine is tolerant of drought after established, loose mulch can help to keep the roots cool. Growth Habit Under optimum growing conditions it spreads by root suckers to cover large areas. This is the hardiest of the passionflower vines, and it does not have to climb in order to produce flowers. If a bushy growth habit is preferred, pinch the vines back after the first growing season. The roots can spread aggressively, and in poorly drained wet soils root rot can occur so be careful not to let it lay in water. Though it dies back in winter, it regrows vigorously each spring, blooming and fruiting. The light green fruits have a tart apricot flavor, perfect for making a refreshing drink with the unmistakable taste of passion fruit (lol think Hawaiian Punch). The fruits should be eaten when ripe, falling easily from the vine. Leaves can also be consumed. Best grown in zones 5-9. Toxicity This plant is moderately resistant to damage from deer. The showy flowers and edible fruit make it an excellent choice for an edible, For pets, dogs and cats often used for calming effects, but its leaves, seeds, and unripe fruit contain cyanogenic glycosides (inactive cyanide) that can cause gastrointestinal upset.
