Blue roses to debut in Japan

The rose has a very long history; it was first cultivated by ancient civilizations 5,000 years ago, and more than 25,000 varieties have been produced since then, in such colors as red, pink, white, and yellow. One color that had proved impossible, however, was blue. The pigment that makes some other flowers blue is called delphinidin, but roses lack the genes to produce it.

Santory makes it true at 3 November 2009 in Tokyo.
