Floral necklaces, also known as leis, are traditional Hawaiian necklaces made from flowers and other natural materials. They are often given as a sign of love and friendship and are used to celebrate special occasions such as graduations, birthdays, and weddings. Leis are typically made with fragrant flowers such as jasmine, tuberose, and gardenia, and can also include shells, feathers, and other natural materials. The vibrant colors and sweet scents of the flowers make them a popular choice for special occasions.
