One scientist decided to putt a "pea" plant into a droughty area to see the reaction. And believe me they where surprised with the outcome.
One pea sent some sort of signal to another pea plant through its roots and basically asked to share soil because their soil was dry.

It's not like the peas speak english, they don't actually talk. They send signals to one another through their roots.

But how, how can the pea send signals? do they have brains? probably not but still, how?
what kind of Plant intelligence is going on?

So, if peas can talk would you eat them?
