Different lighting might help. What type of light are you using? Natural, artificial, etc.?

most cameras either average the image to appear "normal" (even distribution of red green and blue values), or interpret the light according to a pre-set white balance...
using a white backdrop may help give a proper white point, or manually setting the white balance on your camera to reflect your lighting situation. (artificial, cloudy etc)

else you may just have to correct the lighting in your photo editing software....

Editing your photo with your photo editing software is easy. What you want to do with purple flowers that appear blue is to adjust the 'color temperature' to warm, until the color appears true.

I've been using natural light but it didn't seem to help, I'll try a white back drop to see if that helps if not then I'll move on to editing to warmer color temps.
Thanks for the help.
