World's first true blue roses unveiled
The world's first true blue roses were presented to the public for the very first time at the International Flower Expo Tokyo on November 1, 2008.
Blue roses found on the market in recent years were actually white roses cultivated using a dyeing technology, according to a British newspaper, the Daily Telegraph on October 31.
However, the blue roses displayed at the flower expo in Tokyo are the real thing, genuine blue roses.
They were created by genetically modifying the blooms through implanting a gene that stimulates the synthesis of blue pigment pansies, so that the rose petals produce a natural blue color.
