Taihe Zhugao Yam

Taihe Zhugao Yam is a geographical indication certification trademark.

　　The Zhugao yam originated during the Hongzhi era of the Ming Dynasty. It was cultivated from wild yams found in the mountainous regions of the county, and developed over more than 500 years on the alluvial plains along both banks of the Gan River in Taihe County, Jiangxi Province. It is grown exclusively in Jiangxi’s Taihe County, with the largest planting area—over 5,000 mu—in Shuwan Town. The Zhugao yam typically grows more than 100 centimeters deep in the soil. Each yam is about 100 centimeters long and weighs around 400 grams, with a shape resembling a bamboo pole—hence the name “Zhugao” (Bamboo Pole) Yam.
