Why is it that plants do not need to move? How does a nonmotile organism have sex or defend itself? Why are some plants virtually immortal? What is the mechanism that allows plants to exploit a practically inexhaustible extraterrestrial energy source? How do plants regulate the composition of our planet’s atmosphere? Why have there not been mass extinctions among plants as there have been among animals? How do plants communicate with one another? In the end, are plants intelligent organisms?

These are some of the questions the author discusses to demonstrate that plants are wrongly considered to be simple organisms lacking specific behaviour and intelligence. This book promises to be as pleasant a surprise as Alice’s experience in the white rabbit’s warren, in which she encountered a world very different from ours.

The author explains the biology of plants following Einstein's maxim that everything should be made as simple as possible, but not simpler.
