Anyone know of a really blue rose available in the UK? Also, anyone have any idea of a plant with rose-like leaves but has very blue flowers whose petals are unlike a rose?

There is no such thing as a blue rose, mauve but not blue

The blue roses you see for sale on the Ramblas in Barcelona are in fact white ones dipped in dye.

I got seeds for the blue, green and black roses on ebay, I have a couple of plants of each growing, I will let you know in a couple of years what shade of red they are.

A true Blue Rose is seen as the rose growers 'Holy Grail'...

One day it may happen, but short of GM roses, I am not sure if it will be in my lifetime!
