Blue Roses have been sought after for hundreds of years. People’s love for the true blue color have them searching, but they have always been out of reach. Blue roses are also a common symbol in literature, representing impossible prosperity and unrequited love. This is because nature has unfortunately made it so roses can not get that blue pigment in its petals. People have tried to imitate nature, and have created blue roses..but by dying them. This process is done by either cutting white roses and placing them in water with blue food coloring, or injecting blue dye straight into the stems. A company in Japan has believed to genetically modify a rose making it blue, but the color turned to be more lavender in color, making this color still unattainable.
