can plants really communicate with each other?

Good friend Adrian from Immanence blog poses the question HERE.  He cites some very interesting research from the publication Quanta.  

“It turns out almost every green plant that’s been studied releases its own cocktail of volatile chemicals, and many species register and respond to these plumes.”

“Just a few months ago, the plant signaling pioneer Ted Farmer of the University of Lausanne discovered an almost entirely unrecognized way that plants transmit information — with electrical pulses and a system of voltage-based signaling that is eerily reminiscent of the animal nervous system.  ’It’s pretty spectacular what plants do,’ said Farmer. ‘The more I work on them, the more I’m amazed.’

Some of this reminds me of James' A Pluralistic Universe, Lecture IV, on Fechner.  Specifically I am thinking about the section on "the plant soul."  See HERE.
