I can't speak to how conscious plants may be but I find that people rarely give other living things the credit they deserve. I have seen this with dogs over the years. We were told that dogs cannot understand representations of things but my dog barks at every cartoon animal that he sees and when that cartoon animal is a dog he reacts in the way that he does when he sees a real dog.

On a very closely related topic, there is an episode of Joe Rogan's podcast that may interest you. He has a mycologist named Paul Stamets on who, among other things, makes an interesting case for why fungus might be more "conscious" than we may think.
