Author Michael Pollan recently illuminated a mind-bending botanical discovery on The Ezra Klein Show: under the right circumstances, a plant can be anesthetized.
This revelation comes courtesy of a provocative group of scientists who refer to themselves as "plant neurobiologists." It is a highly controversial moniker within the broader scientific community—largely because plants do not actually possess neurons. The title acts as an academic troll aimed at conventional botanists, but the group's experimental findings are entirely serious.
In one fascinating study, these renegade researchers tested human anesthetics on reactive flora. They utilized xenon gas, an inert substance that surprisingly has the power to knock out human beings despite triggering no apparent chemical reaction. When the gas was administered to carnivorous plants and the Mimosa pudica—a highly sensitive tropical plant famous for swiftly collapsing its leaves when touched—the results were uncanny. The plants stopped reacting completely.
They entered a dormant period where they appeared to be "asleep," only to eventually "wake up" and regain their normal reactive abilities.
"The fact that plants have two states of being is a very pregnant idea," Pollan noted, pointing out that scientists have identified clear "lights on" and "lights off" modes in these leafy subjects.
While Pollan concedes this isn't definitive proof of plant consciousness, he describes the phenomenon as "spooky and interesting." Naturally, this scientific breakthrough prompts unsettling ethical questions for anyone with a garden. If a plant can be anesthetized, can it feel pain? When we mow the lawn, is the sweet, nostalgic scent of freshly cut grass actually the chemical equivalent of a distress signal?
It is a grim philosophical rabbit hole to tumble down. Yet, as the podcast discussion highlighted, humans are uniquely adept at compartmentalizing empathy. Society currently grapples with abstract, Silicon Valley-driven fears about whether future artificial intelligence might deserve moral consideration, even while collectively turning a blind eye to the very real, industrialized suffering of conscious livestock.
Whether or not your houseplants possess a conscious inner life remains an open scientific mystery. But the next time you go to aggressively prune your garden, you might just look at your shears a little differently.
