Yes, they really do. We already knew that plants do think, in their own ways, but now we also know that trees (probably all plants) also communicate among themselves. We must thank Suzanne Simard, from the University of British Columbia, which confirmed this through field research using sophisticated experiments which show that trees not only communicate but also cooperate and send defense signals to each other. Mother trees nurture their young using the symbiotical relationships between a mycorrhizal network of fungi and their own roots. For more information on the subject, please watch a TED TALK from Ms. Simard, titled How Trees Talk to Each Other.
