These days, tea is harvested all over the word, really. The most well-known tea growing regions are located in Japan, China, India and Sri Lanka. Different regions are generally known for a specific type of tea. Perhaps the most famous tea growing region--although maybe not necessarily the highest quality--is the Darjeeling region of India, which is mainly known for the black tea it produces, although it is technically closer to an oolong tea.
Tea is grown in bushes, but only the top leaves are picked/cut from the bush by a special machine. Then the tea goes through a process to make it the type of tea that you find on the shelves. Because of the way tea is harvested the actual bush it comes from can be thousands of years old.

Most tea is grown in Asia and Chinese tea comes from China. Tea grows on a bush and only the top of the bush is harvested leaving the bottom branches alone. That means some tea plants are very old. The Chinese still prepare their tea leaves much the same way they did a thousand years ago. Small farmers grow and prepare the tea for sale and buyers come to deal with the Chinese government on the price. Some of the best tea in the world comes from China.
