Ok, you probably read the title and thought of how outrageous it sounds but it's possible. There are actually genetically modified tobacco plants out there that glow in the dark because of firefly genes inserted in them.
Roses aren't that far from being next considering how popular they are and that genetically modified "blue" roses exist that borrowed genes from pansies. (They were actually lavender because they failed to stop the rose from producing red pigments)
Now, I've come across a project that plans to make glowing plants as alternatives to street lights. They've been successfully funded in Kickstarter last June and are currently working on their projects and among them is a glowing rose.They haven't decided on what color to choose yet though and probably what type it's gonna be.
What do you guys think? Since this is genetic modification, if the glowing roses aren't sterile there's a chance they might pass on the bioluminescent gene to their offspring. Imagine your favorite rose bush glowing at night! Do you think they'd be welcome additions to gardens or are they just for novelty?
