Roses, both fresh and dried, often appear during festive occasions. However, fresh roses do not last long, and dried flowers are marinated with environmentally unfriendly chemicals. This paper proposes the procedure and experiment of drying roses by the freeze-drying method. After drying by the proposed method, the results show that the rose color changes very slightly but still retains its natural, eye-catching, and environmentally friendly appearance.
