Climbing Plants - What Is Thigmatropism?

CrowdScience listener Eric, in New Zealand, has noticed his wisteria growing towards a neighbouring tree. He thinks that it actually knows where it’s going. But how can a plant have a sense of direction?

Plants don’t have the advantage of brains or eyes, but that doesn’t seem to stop them from being clever enough to find out from their environment where to move and how to get there – all while being rooted to the spot.

Marnie Chesterton visits the Natural History Museum and Kew Gardens in London, home to the largest collection of living plants in the world, to discover how plants make their manoeuvres, and talks to botanists and plant biologists for the latest findings on the mysterious life of climbing plants.
