Kangkong is the Asian-originated name for what in English is known as water spinach, a leafy green water vegetable.

There are various names for kangkong, which is the name common in the Asia-Pacific region. Other names of kangkong are water morning glory, swamp cabbage, river spinach, Chinese spinach and water convolvulus. The scientific name for kangkong is ipomoea Acquatica and the plant is believed to have originated from Asia.

Kangkong or water spinach is a soft-stemmed aquatic or semi-aquatic perennial plant found in tropical and sub-tropical regions. The leaves are flat and vary in shape depending on variety, from heart-shaped to long, narrow and arrow-shaped. The two common varieties of kangkong we grow are the one with green stem that bears white flowers and the one with white stem that bears pink flowers. If the leaves are not harvested early and it flowers, it produces seeds, which can be planted.

In Papua New Guinea, kangkong naturally grows along riverbanks and in swampy areas and lakes. There is not much work or maintenance required in growing kangkong. Kangkong grows roots from the stem's nodes when planted so we don’t grow them from the seeds. It does not have any season and grows all year round, thriving where there is plenty of water and moist soil. It is weather-resistant.
