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.[1][2]
Besides roses, other cut flowers like the chrysanthemum, carnation, hydrangea and some species of orchids can also be colored using the same method.[3]

[edit] History
The uncomplicated process has been known for more than a millennium.[citation needed] Several companies have moved to patent the process.[citation needed] It appears they have been partially successful.[citation needed] Three of them offer rainbow roses under the name "Happy Roses."[citation needed] It will be up to the courts to decide if the process can be patented.[citation needed] You can grow a rainbow rose by putting dye in the soil and waiting two months for it to grow.[dubious ]
[edit] Cultivars
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.[citation needed] 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+.[citation needed]
[edit] Color combinations
The rainbow rose is available with different colour combination. The most popular is the variant with all the colors of the rainbow. There are also the tropical variant with combinations of red/pink and yellow, and the ocean variant with combinations of green and blue.[1] Other color combinations are also possible, though black and white are impossible to make. The position of the colours can make just as much of a difference as different colors.
