Is Red Bush tea really or is it a separate kind of plant?

Rooibos tea, also known as red bush tea, is a caffeine-free herbal tea made from the leaves of the Aspalathus linearis plant, which is native to South Africa. It is not the same as red tea, which is made from the leaves of the Camellia sinensis plant and contains caffeine. Rooibos tea has a naturally sweet and slightly fruity flavor, and it is often used as a bedtime tea or as a caffeine-free alternative to black tea or coffee.
