In the Hawaiian culture, if you are to wear a flower behind your left ear, you are married and/or unavailable. Wearing a flower on the right side signifies the opposite, that the person in question is single and possibly looking for love. The tropical islands of Hawaii are known for playing host to some of the world’s most beautiful flowers. From the official state flower of the bright yellow Hibiscus to the fragrant pink Plumeria trees, there are a wide variety of exotic flowers to touch, see, and smell.
