The orchid lei is a common lei used in Hawaii. The purple dendrobium orchid is well known for its bright colors, durability and longevity. In the wild, they grow on trees or rocks and get their nourishment from whatever the wind or rain brings. Lei are a traditional symbol of Hawaii to millions of visitors worldwide. A lei should be a welcomed celebration of affection from one person to another. You should always accept a lei, and it is rude to remove a lei from your neck in the presence of the person who gave it to you. Anyone can wear one, anytime - just like a Pineapple Palaka necktie!
