Colorful Eternity Flowers Instead of Artificial Rosa preserved roses look and feel like freshly-plucked roses and yet can last much longer. Our roses cannot be compared with dried, freeze-dried, artificial, or silk roses. These are real rose heads that have been harvested at the quality peak and preserved to stabilize vivid color and maintain natural appearance and feel. Rosa preserved roses come in a variety of colors and are great for designing arrangements. With proper care our preserved rose heads can last 3~5 years or longer.
