Are there roses naturally colored blue? Where can I find them?

Answer 1

Nope, there aren't any roses naturally colored blue.

"Since roses lack a gene to produce delphinidin, the primary plant pigment that produces true blue flowers, blue roses were traditionally created by dyeing white roses. So-called "blue roses" have been bred by conventional hybridization methods, but the results, such as "Blue Moon" are more accurately described as lilac in color. However, after 13 years of joint research by an Australian company Florigene, and Japanese company Suntory, a blue rose was created in 2004 using genetic engineering. The delphinidin gene was cloned from the petunia and inserted into a mauve-blend rose, the Old Garden Rose 'Cardinal de Richelieu' (a Rosa gallica). However, since the pigment cyanidin was still present, the rose was more dark burgundy than true blue. Further work on the rose using RNAi technology to depress the production of cyanidin produced a very dark mauve plant, with only trace amounts of cyanidin."

Answer 2

I've read of Australian geneticists who are working to genetically modify roses to include the blue pigment (I think it's called anthocyanin, but not positive), by inserting the gene from the delphinium plant, which is a true blue color.

I do not know how far along this research is, but, the article I read was 3-4 years ago.

Answer 3

It is true that there are no true blue roses. However, there is a Dutch breeder that has come closer than anyone ever and I'm sure it is only the beginning. Supposedly, these roses are to be released to the public in the near future and I can't wait. Here is that site if you are interested.

Answer 4

No. Roses do not have a blue gene in their makeup. Short answer.
