A Japanese firm has announced it is set to sell the world's first genetically-modified blue rose.
There is no natural blue pigmentation in the flower to allow a blue rose to be genetically bred naturally.
But in 2004, a company managed to develop a natural blue rose by splicing the gene that leads to the synthesis of the blue pigment Delphinidin in petunias. Now the 20-year research project is set to hit Japan, marketed as a "luxurious gift for special occasions such as wedding anniversaries."
They will be sold for 2,000 and 3,000 yen ($22 and $33) per stem, about 10 times more expensive than normal.
