Passiflora foetida, also known as Love-in-a-Mist and Pop Vine, is a perennial vine that can grow to 13 feet tall. It has now spread throughout the tropics in America, Asia, and the Pacific Islands. Fast-growing vine, particularly in warm, wet, tropical regions. It climbs by means of clinging tendrils and can be kept as an container plant. The long tendrils need lots of support for climbing. A must for any collection. This is a very variable species; the flower color can be pink, white, blue, or purplish. In the wild the plant blooms from June to September, however the bloom period will probably be extended when cultivated in the greenhouse. Flowers are about 2 1/2 inches wide. The flowers are followed by small marble sized fruit that has a sweet-acid taste. These orange fruits, although much smaller, taste the same as those from Passiflora edulis. The foliage can be variable also. The leaves have a strong scent when touched. Pruning is a must to keep the vine healthy. Prune off less vigorous growth and occasionally prune back vigorous growth to promote flowering. When established, and without care, the passion fruit can easily overtake other garden plants, shading them from sun. Hardiness zones 9-11, (4øC/40øF, -5øC/25øF) in Winter. A very vigorous plant. Protect from frost or plant in frost free areas. Keep the atmosphere humid through the Summer and place in full sun, can tolerate partial shade. Passiflora foetida loves the warm humid Tropics. You may need to water your plants on a daily basis during the hottest Summer months. During the Winter the roots should be kept moist, but as growth will be much slower you will probably only need to water once a week, depending on growing temperature. It will do best in a loam based mix with a little peat moss. Fertilize at least once every two weeks in the growing season. If their pot is too large or if they have an unrestricted root run then the whole plant will simply get bigger and bigger but it will refuse to flower and therefore produce the fruits. By limiting the pot size you are limiting the ability to grow and this is seen as a threat, so the natural mechanism is to produce seed for the next generation. A suitably sized pot for an adult plant would generally be of 12 inches in diameter.
