One doesn't always think of flowers when they think of tea, however, some of the most commonly enjoyed teas in the world are flavoured with the oils and petals of various flowers. Earl Grey tea gets its unique flavour from the oil of bergamot blossoms. Jasmine and rose have been used to flavour black and green teas all over the world, and chrysanthemums are brewed into a sweet tea with honey for a unique and satisfying treat.
