The rainbow rose is a rose whose petals have been artificially colored. The method exploits the rose’s natural processes by which water is drawn from the stem. By dividing the stem and soaking each part in different colored water, the colors are drawn into the petals, resulting in a multicolored rose. With these changes to the rose, it prevents them from living as long as an uncolored rose. The colors are artificial. Besides roses, other cut flowers like chrysanthemum, carnation, hydrangea and some species of orchids can also be colored using the same method.
