This type of vegetable is called passionflower. Whenever it comes into contact with water, the abundant saponin in the leaves of the vegetable will neutralize with the water and create foam. Passionflower is also known as passionfruit, passionflower vine,… its scientific name is Passiflora foetida.

The plant originates from countries in South America, Central America, or some countries near the Caribe region.

In Vietnam, passionflower is quite popular, especially in provinces in the North such as Bac Giang, Yen Bai, Quang Ninh,… or some mountainous areas with altitudes ranging from 500-1000m above sea level.

The leaves of passionflower and their ripe fruits are both edible and have a delicious aroma. The young shoots of passionflower can be cooked into boiled or stir-fried dishes. The ripe fruits can be peeled and eaten directly.
