Jianchuan White Kidney Beans

Jianchuan White Kidney Beans

　　White kidney beans, scientifically known as Phaseolus multiflorus, derive their name from their diverse flower colors. They belong to the Fabaceae family, subfamily Faboideae, tribe Phaseoleae, and genus Phaseolus. Originally native to Mexico and Argentina in the Americas, white kidney beans have been cultivated and domesticated to adapt to cool, moist highland environments. The largest cultivation areas are found in countries such as Argentina and the United States in the Americas, the United Kingdom in Europe, and China and Japan in Asia. They were introduced and cultivated in China only in the late 16th century. Today, they are grown across various provinces and regions in China, with major production in Yunnan, Guizhou, and Sichuan. Among these, Dali, Lijiang, and Lanping in Yunnan have particularly large cultivation areas.

The seeds of kidney beans come in a variety of shapes, including kidney-shaped, oval, flat, cylindrical, and spherical. Their colors also vary, ranging from white, black, black-purple, green, to speckled patterns. The size of the beans differs greatly as well — some are as small as soybeans, while large white kidney beans can be about 21 millimeters in length and 9.5 millimeters in thickness, several times larger than soybeans, earning them the title of the "crown jewel" among beans. White kidney beans are a premium bean variety commonly used in Western cuisine. With their plump, uniform, and glossy appearance, they make an excellent accompaniment to dishes and are renowned both domestically and internationally.
