While a single person wears a flower above the right ear in Hawaii, a person in a committed relationship places it above the left ear. This is a signal that a person is either available or unavailable. The plumeria flower is native to Hawaii and is a popular choice to wear above the ear.
Flowers are very important in Hawaiian culture. Another Hawaiian custom, which dates back to the Polynesians that came to these islands, involves the giving of a flower lei or garland. Leis are a symbol of welcome, affection or friendship. They can be made from leaves and flowers. However, there are etiquette rules that a person should follow if they are given one. If offered a lei, it is considered impolite not to accept it.
