All tea comes from varieties of the plant Camellia Sinensis. In the wild, the plant grows to the size of a tree. There are, in fact many ancient tea trees still thriving in China, active testaments to a long-standing tea culture in the country where this beverage was first drunk. For the convenience of plucking, most tea plants are pruned down to the size of a bush, often giving the tea estate the appearance of a manicured garden.
