Potpourri pieces are PETALS that are used to make potpourri, a fragrant mixture of dried, naturally fragrant plant materials. PETALS are often used in potpourri because they are colorful and have a pleasant scent. Potpourri pieces can also include other dried plant materials such as leaves, stems, bark, and seeds. The PETALS are usually dried and then mixed with essential oils to create a pleasant aroma. Potpourri pieces are often used in aromatherapy and home decor.
