Floral wreaths, also known as leis, are traditional Hawaiian garlands made from flowers and foliage. They are often given as a sign of welcome or farewell, and are used to celebrate special occasions such as weddings and graduations. Leis are typically made from fragrant flowers like plumeria, tuberose, and jasmine, and can be made with fresh or dried flowers. They are often decorated with shells, feathers, and other natural materials.
