Tulips in natural habitat occur in many parts of the world: in warm regions of Europe, northern Africa, in some parts of continental Asia, coasts of China and in Japan. It is at the same time one of the most commonly grown species of flowers. These plants are particularly liked by the Turks. A characteristic shape of Turkish tea glasses that are well-known all over the world has been inspired by the tulip flower. Symbolic images of tulips can be also found on Turkish graves – a red calyx and a green stem with a leaf symbolize the soul that lives forever and its life after death.
