Plant scientists are wondering if plants really communicate with each other (and with insects and other organisms) or if they just “eavesdrop” on each other’s “soliloquies.”
At stake in the debate are the definitions of communication (e.g., is it necessarily intentional, and is intentionality necessarily conscious intentionality?) and behavior (is it something that only animals do?).
What seems certain is that plants can and sometimes do share information. This article from Quanta summarizes recent research.
