Doc Green's shadowboxes are composed of flowers and plants that were grown on her flower farm in Georgia. The materials in each box are either air-dried, pressed, or dried in silica beads. Because the materials are entirely real, they are delicate. While these works of art are expected to last many years, their longevity depends on you. To retain vibrant colors, hang your shadow box inside and away from direct sunlight. Sunlight fades the color on dried flowers, so it is important to keep the shadow box away from direct sunlight.
