Title: The secret life of plants

The secret life of plants: how they memorise, communicate, problem solve and socialise (

Amy Fleming

Mancuso and his colleagues have become experts in training plants, just like neuroscientists train lab rats. If you let a drop of water fall on a Mimosa pudica (, its kneejerk response is to recoil its leaves, but, if you continue doing so, the plant will quickly cotton on that the water is harmless and stop reacting. The plants can hold on to this knowledge for weeks, even when their living conditions, such as lighting, are changed. “That was unexpected because we were thinking about very short memories, in the range of one or two days – the average memory of insects,” says Mancuso. “To find that plants were able to memorise for two months was a surprise.” Not least because they don’t have brains.

One of the most controversial aspects of Mancuso’s work is the idea of plant consciousness. As we learn more about animal and plant intelligence, not to mention human intelligence, the always-contentious term consciousness has become the subject of ever more heated scientific and philosophical debate ( “Let’s use another term,” Mancuso suggests. “Consciousness is a little bit tricky in both our languages. Let’s talk about awareness. Plants are perfectly aware of themselves.” A simple example is when one plant overshadows another – the shaded plant will grow faster to reach the light. But when you look into the crown of a tree, all the shoots are heavily shaded. They do not grow fast because they know that they are shaded by part of themselves. “So they have a perfect image of themselves and of the outside,” says Mancuso.

Another misconception is that plants are the definition of a vegetative state – incommunicative and insensitive to what is around them. But Mancuso says plants are far more sensitive than animals. “And this is not an opinion. This is based on thousands of pieces of evidence. We know that a single root apex is able to detect at least 20 different chemical and physical parameters, many of which we are blind to.” There could be a tonne of cobalt or nickel under our feet, and we would have no idea, whereas “plants can sense a few milligrams in a huge amount of soil”, he says.

Plant experimentation is fascinating stuff. Hard to explain it without putting your toe in consciousness.
