All true teas, including black, green, white, and oolong, are brewed from the leaves of Camellia sinensis. This evergreen shrubby tree is native to China, where tea originated several thousand years ago, but now grows in many areas of the world, especially in semi-tropical climates.
The leaves take on a slightly different flavor depending on where they are grown, and there are quite a few cultivators of Camellia sinensis as well, each with its own unique characteristics, so although all tea is from the same plant, there are seemingly endless varieties to choose from.
