Q.Rozanne Geraniums
The flowers of the Rozanne geranium is supposed to be blue, which mine were for the first season or two. Since then (the last two years) the flower color has been fuchsia. Had I wanted plants with fuchsia flowers, I would have purchased and planted them! Is there anything I can do to turn the flowers of my Rozanne geraniums back to blue?

It seems that geraniums have the unusual property of changing their flower color based on the temperature. I'm not sure if providing shade would allow them to change back, but it's worth a try. Here is more information:
