In India tea was a native plant and was grown and used by locals living in remote areas. It was in the late 18th century that East India Company started experimenting with growing tea in India. Until then all the tea for Europe came from China. The commercial production of tea was slow in developing because the use of Chinese plants, which were good for a colder climate, did not do as well in the low lands. The British were slow to recognize the indigenous plants and their commercial importance. However, when it looked like the Chinese might not renew their treaty with Britain in 1833, the British really became committed to growing tea in India. They then recognized the indigenous plants and commercial tea production took off in the Assam area.
