Wild Tongmu Zheng Shan Xiao Zhong is picked one bud at a time, entirely by hand, and entirely by native residents living within the reserve. The tea plants are wildly propagated by seed, and are left untended. This natural selection creates genetic variation and diversity between each standalone tea bush. Each bush grows between one and three meters high, and grows out of cracks in the volcanic rock of the Tongmu mountains. Tongmu is a tiny region that has been designated for special protection and recognition. Non-residents are not allowed into the preserve without special approval and sponsorship from a resident. The region of Tongmu is unique within the Wuyishan region for its volcanic rock formations, and extremely thick vegetation coverage and biodiversity. Nestled along either bank upstream of the Jiuqu (Nine Bends) Brook, the mountains create a unique microclimate, perfect for many species of birds and a healthy ecosystem. Mountain spring water springs out of the ground and runs down every slope, and the rocky land and cold weather make for slow-growing but singularly incredible tea.
