"All types of 'true' tea actually originate from the same plant. The botanical name for the tea plant is Camellia sinensis. This plant originated in southern China thousands of years ago, and has been cultivated and consumed for hundreds of years. Camellia sinensis has two main varietals: camellia sinensis var. sinensis, which grows primarily in China and other East Asian countries and has a milder, mellower character, and camellia sinensis var. assamica, which grows primarily in India and is generally heartier and more robust."
