London: Not naturally available, the mythical blue rose will be on sale in the US and Canada in November.
Named `Applause,` the rose is the product of a genetic modification to synthesise a pigment found in blue flowers know as delphinidin.
And while it seems like purple, it is the nearest to a blue flower scientists have come so far.
The only blue roses available have been white coloured which are dyed blue. This is because nature is unable to produce blue pigments.
However after 20 years of trying, Japanese company Suntory Ltd finally made the breakthrough, the Daily Mail reports.
Since then the blue roses have been available to buy in Japan - although at 15-20 pounds for each stem, they are strictly for very special occasions.
Blue roses are also believed to have mythical qualities.
