I think you're going to need to settle on something that is not quite blue. Here are three of my favorites in that spectrum. I know they look blue in the picture, but they're actually more purple. The Vascostylis is the closest to being true blue in real life.

There are no true blue flowers in nature. All "blues" are actually various shades of violet that appears blue because of how the cells reflect light. Also, there are no "blue" birds in nature either. They're all grey, but they appear blue because of how the light is reflected off the feathers. (Sorry; the "bluebird of happiness" is actually grey.)
In modern digital photography, "blue" flowers appear unnaturally blue because of a phenomenon called the "reverse Ageratum effect" where the digital sensors either perceive more blue than is seen by the human eye or because of over correction by the processor. This is in contrast to the old "Ageratum effect" from color film days where the effect is believed to be based on “an anomalous reflectance due to the fact that some pigments reflect infrared light that is picked up as red by the film“. This was first discovered while photographing Ageratums for the first colour seed catalogues.
