Hibiscus, a flowering plant grown in tropical and subtropical climates, consists of large trumpet-shaped flowers with five or more petals. It tastes tart and sweet at the same time with a very pleasant full bodied flavor that produces a ruby red liquor. Fraser Teas uses hibiscus to enhance many of our teas. Consider hibiscus to be nature's answer to candies like Sweet Tarts. It has been known to help alleviate nausea and lower blood pressure.Â
