Rainbow roses are exactly what they sound like... roses in the colors of a rainbow. They look like a box of crayons had babies with a bunch of roses.
They were designed by Peter Van de Werken, who owns a flower company close to Den Bosch in southern Holland. Rainbow roses are real roses, but they can't be purchased as a rose bush. They are only available as cut or dried flowers.
These special roses are made by inserting dye into the stem of the roses while they are growing, which results in the color being absorbed by the petals of the flower. They are not easy to make, as they take a bit of careful engineering. Rainbow roses are used to create unusual and striking floral arrangements, wedding bouquets, and they are often given as gifts.
People either love them, or hate them.
There is no middle ground with these brightly colored flowers in shades of blue, purple, green orange, pink, and yellow.
