Blue rose
A rose artificially colored blue, symbolizing mystery and the unattainable.
A blue rose is a flower from the genus Rosa (family Rosaceae) that shows blue-to-violet coloring, achieved only through artificial methods like dyes, since roses naturally lack the gene for true blue pigment. Because they cannot occur in nature, blue roses have come to symbolize mystery or the unattainable. In 2002, scientists used genetic modification to produce a mauve rose by introducing delphinidin, a blue pigment found naturally in other plants, into a white rose.

Lore & Background
Blue roses do not exist in nature because roses lack the specific gene to produce a true blue color. Historically, they were created by dyeing white roses. In the 12th century, Andalusī agronomist Ibn al-'Awwām al-Ishbīlī wrote in his book Kitāb al-Filāḥah about azure blue roses made by placing a blue dye into the bark of the roots. So-called 'blue roses' bred by conventional hybridization, such as 'Blue Moon', are more accurately described as lilac in color.
In 2002, after thirteen years of collaborative research by Australian company Florigene and Japanese company Suntory, a genetically engineered rose containing the blue pigment delphinidin was created. The genetic engineering involved adding a gene for delphinidin cloned from the pansy into a purplish-red Old Garden rose 'Cardinal de Richelieu', then using RNA interference to depress other color production. However, the RNAi did not completely knock out the activity of the DFR protein, and the acidity of rose petals degraded the delphinidin, resulting in a mauve or lavender color rather than true blue. As of 2008, the GM roses were grown in test batches in South Hampshire. Suntory sold 10,000 Applause blue roses in Japan in 2010 at prices from 2,000 to 3,000 yen per stem.
Reader's Guide
The blue rose holds significance as a symbol of mystery and the unattainable, precisely because it does not occur naturally. Its creation through artificial means—first by dyeing in the 12th century, then by genetic engineering in 2002—reflects human persistence in overcoming biological limitations. The 2002 genetically modified rose, though not truly blue, represented a milestone in floral biotechnology, involving the transfer of a pigment gene from a pansy and the use of RNA interference to suppress competing colors. The resulting lavender or mauve rose, marketed as 'Applause', demonstrated both the potential and the challenges of genetic engineering: the acidity of rose petals and incomplete gene silencing prevented a true blue. Culturally, the blue rose appears in traditions where owning one grants wishes, and in modern media such as the Animal Crossing video game series, where it is notoriously difficult to breed. Its legacy lies in its embodiment of human ingenuity and the enduring allure of the impossible.

Frequently Asked Questions
What is a blue rose?
A blue rose is a member of the Rosa genus that displays blue-to-violet coloring, but this hue is only achievable through artificial means such as dyeing or genetic modification, since the plant naturally lacks the genetic pathway for true blue pigment.
Can blue roses occur in nature?
No, roses are genetically incapable of producing true blue pigment on their own, so every blue rose ever seen has been the result of human intervention.
How far back does the history of blue roses go?
The earliest recorded instance of an artificially blue-colored rose dates to the 12th century, when a dyeing technique was described in the agricultural text Kitāb al-Filāḥah.
What does a blue rose symbolize?
Because the flower simply cannot exist in its natural form, it has long been associated with mystery and the idea of something beautiful yet fundamentally unattainable.
Who produced the first genetically engineered blue rose?
In 2002, Florigene and Suntory collaborated to create a mauve-colored rose by inserting the delphinidin pigment gene—naturally found in other plant species—into a white rose, though the result was a pale lavender rather than a true blue.
