Trandafirul albastru

To produce a naturally blue rose has been a dream of horticulturalists for almost as long as people have been breeding flowers. It turns out to be essentially impossible to do by traditional plant husbandry, and attempts have proved futile for so long that the blue rose itself has become a symbol of the impossible or the seemingly impossible, and only the rarest achievements call for their presentation as gifts. And until recently, even those rare occasions had to be served by artificially blue roses made by growing white roses in tinted water. Now, however, the Japanese company Suntory, in partnership with Australia's Florigene, have created a transgenic rose which incorporates a petunia gene to achieve a pale lilac color which is really only barely blue. It took them 13 years of work to do it, however, so I guess they've decided pale lilac is close enough.
