The Secret Life of Plants (1979)

A rather unknown documentary from 1979 about plants and their "feelings" -- and how they can sense the world around them. Based on the 1973 book "The Secret Life of Plants" by Peter Tompkins and Christopher Bird, it documents controversial experiments that claim to reveal unusual phenomena regarding plants such as plant sentience, discovered through experimentation. It then goes on to discuss philosophies of mind, and life.

Soundtrack by Stevie Wonder.
