In 2004, two dutch companies, River Flowers and F.J. Zandbergen, experimented and successfully grew a rose that had its petals rainbow colored. As petals get their nourishment through stem, the idea is to split the stem into several channels and dip each one in a different colored water. This way all the colors will be drawn by the stem into petals and resultant rose will have all the colors in it. The same method can be applied to other flowers especially to
Chrysanthemum and
Hydrangea. You can use the same idea to color any flower, anyway you like.
The
rainbow rose is a
rose which has had its petals artificially colored. The method exploits the rose's natural processes by which water is drawn up the stem. By splitting the stem and dipping each part in a different colored water, the colors are drawn into the petals resulting in a multicoloured rose.
Besides roses, other cut flowers like the
chrysanthemum,
carnation,
hydrangea and some species of
orchids can also be colored using the same method.
A lot of research was done to find the best cultivar for this unique coloring process, with the result that the Vendela Rose is the only cultivar that absorbs all the different colorants perfectly
. The Vendela Rose is a
Hybrid Tea, cream rose that grows in Holland, Colombia and Ecuador. When the rose is in full bloom it has a flower diameter of 6 cm and a stem length of 40 to 100 cm. The rose isn’t scented.Other
cultivars that can be used for this coloring process are Rosa La Belle and Rosa Avalanche.
