Can a planet with blue glowing plants exist?

I have a planet where I want all plants to be blue and glowing. I was thinking that they could use something other than light for energy. I want the plants to always glow. The atmosphere is basically the same as Earth's. So is the soil. So I want to hear some of your ideas/suggestions.

Main Point: What are some ways for plants on a planet with Earth's atmosphere and soil to glow blue all the time?
