"Hometown of Gardenia" -Tanghe County

As the "Hometown of Gardenia", Tanghe County enjoys a long history of gardenia cultivation. Both Liu Xiang's Supplementary Records of Famous Physicians (Han Dynasty) and Li Shizhen's Compendium of Materia Medica (Ming Dynasty) stated that "Gardenia grows in valleys and on mountains of southeast Nanyang". Humid climate caused by the unique geography featuring mountains on three sides, clay soil and sandy loam all together provide an excellent environment for the cultivation and growth of gardenia trees, and the gardenia produced there is of high quality. At present, there are 130,000 mu (21,450 acres) of gardenia trees in mountainous areas in Tanghe, accounting for over half of the cultivated area in the country. The annual processing capacity of dry gardenia fruits is 20,000 tons, with extracted natural edible pigment of 300 tons, valuing 200 million yuan. Gardenia fruits are processed on site, realizing the increase in value. ? ?
