Tea plants are nothing different , they are just plants from which we get tea leaves to prepare tea. these plants usually grow in hilly areas like ooty, Assam etc. Assam is the best known place for its tea plants. It is known world wide for its tea plants. these plants are grown till the height of at least 1 feet and then are cut down to get tea leaves. If these grow more than 1 or 1and a half feet, these loose their fragrance and are useless then.
