A truly blue rose has been the Holy Grail of rose breeders since 1840, when the horticultural societies of Britain and Belgium offered a prize of 500,000 francs to the first person to produce a blue rose.
Molecular geneticists with Florigene and Suntory achieved the prize that had long eluded conventional rose breeders by combining something old, something new, something borrowed, and something blue.

Roses do not have the enzyme "delphinidin" in them to make them blue. They are now extracting this enzyme from pansies and other flowers, and directing this pigment into the pigment pathway of other roses.
In a few years, you should see more "blue" roses.
