One of the new books I've recently purchased is called "Planta Sapiens: The New Science of Plant Intelligence" by Paco Calvo with Natalie Lawrence.
I picked it up because I remembered years ago watching some episodes of a docu-series on Netflix that was in a similar vein; regrettably I don't recall the name of the series and wish I watched it in its completion, but it talked about stuff that is not really in the public knowledge, and new discoveries at the time.
I've wanted since then to learn more, but it always seemed like information was spread out and hard to engine search, or not available to the public at all, at least at the time I was looking, so I kind of have up (I could also just suck at looking things up lol).
I'm hoping this book will finally be what satiates my need to learn more about the subject.
