I got my firefly petunias from light.bio around a month or so ago and they’re now just starting to take off. This picture was taken in a dark room with no windows, though I’m sure the phone brightened it up a bit. They aren’t as bright as I was imagining, but I still find them neat.
No they didn’t crossbred it. Fungi and plants are so far apart in the tree of life that suggesting this is ludicrous. You can’t get a fungal spore and place it in a petunia’s flower and get a hybrid.
DNA manipulation in a lab and selective breeding are fundamentally different. It’s silly to try to compare both.
