Description/Taste
Kangkong leaves are medium to large in size and lanceolate or arrowhead-shaped, averaging 10-20 in length and 2-8 centimeters in diameter. The smooth, long green leaves grow in an alternate pattern and form on hollow stems that can grow up to 2 to 3 meters in length. These stems, or vines, are commonly found in aquatic locations and can float on the water and hold the leaves above the water line. Kangkong leaves are tender, and the stems are crunchy, offering a slippery texture when cooked and a mild, sweet, and nutty green flavor.

Ethnic/Cultural Info
Kangkong is a humble vegetable that commonly accompanies meat and rice dishes in Asia and is often ordered as an afterthought. In the Philippines, kangkong adobo is a traditional recipe that incorporates coconut milk, vinegar, sugar, garlic, and bay leaves to make an adobo sauce to mix into the sautéed Kangkong. Kangkong is valued for its nutritional content, and because it grows easily and is available year-round in Asia, it is a well-known and loved side dish in Southeast Asia.
Geography/History
Kangkong leaves are believed to be native to India and Southeast Asia. The earliest instance of Kangkong is said to date back to the Chin Dynasty in China in 304 CE. The fast-growing, easily propagated species was spread by Asian immigrants moving from their home areas to other parts of the world for work and has spread to Africa and South and Central America. Kangkong was brought to the United States in the 1970s, and although it never took off as a popular vegetable, it grew so voraciously that it is considered locally and federally to be a noxious weed in certain states. Today Kangkong leaves are available in fresh markets and specialty grocers in Asia, Southeast Asia, the Americas, and Africa.
