Passiflora foetida, the running pop, also known as love in a mist or the foetid passionflower, is a perennial herbaceous vine that originates from tropical America, and which has spread in many tropical regions. The leaves have an unpleasant odor when crushed, hence its common name foetid passionflower, stinking passion flower, and also ill-odoured passionflower. The tiny fruit is however edible, although this vine is not often grown for its fruits.

This vine is not very frost hardy and will freeze bellow 28°F (-2°C), so it is best to grow it in USDA zones 9b and warmer. Grow in containers, it will often freely flower, and even set fruit if hand pollinated.

Passiflora foetida is a perennial herbaceous vine, that has 3 to 5-lobed leaves, and very seldom lanceolate leaves (E.g. Passiflora foetida var. subintegra)

There are many varieties of running pops, and depending on these varieties, flowers are pink or white.

The fruit on the foetid passionflower is edible, and is not foetid itself. In fact, they are quite tasty. It is sometimes used for juice production, but is seldom eaten raw, as the fruit is very small, with an average diameter of 1-1.5 in. (2,5 - 3,8 cm) The fruit is generally globose, and is yellow, pink or scarlet, depending on the variety.
