The Rainbow Roses !! It's Awesome.The Rainbow roses were created by Dutch flower company owner Peter VanDe Werken, who produced them by developing a technique for injecting natural pigments into their stems while they are growing to create a striking multicolored petal effects. The dye are produced from natural plant extracts and absorbed by the flowers as they grow. A special process then controls how much color reaches each petal- with spectacular results. By treating the stalk with natural pigments, Van De Werken has manage to make each petal a different color. The pigment is absorbed and travels to the petals where it changes their hue.
