These "rainbow roses" were created by Dutch flower company owner Peter van de Werken, who produced them by developing a technique for injecting natural pigments into their stems while they are growing to create the striking multi-colored petal effect:
The dyes are produced from natural plant extracts and are absorbed by the flowers as they grow.
A special process then controls how much colour reaches each petal — with spectacular results. By treating the stalk with natural pigments, van de Werken has managed to make each petal a different colour. The pigment is absorbed and travels to the petals where it changes their hue.
Mr van de Werken, 36, said: "We used to only sell single colour flowers but the market for them took a dip. Myself and my colleagues started looking for something a bit different and came up with the idea of having different-coloured flowers. First of all we tried spraying the flowers but that did not work. Then we tried the dye. It took us about six months to get it right and we still make mistakes."
