Author, plant lover and former BBC documentary maker Jonathan Drori joins the show for a chat about some of the latest botanical news.
Drori discusses the discovery that purslane, a common weed, creates a novel type of photosynthesis, providing important clues about how to create drought resistant crops.
Jonathan is also fascinated by the discovery of a carnivorous pitcher plant - the first known to grow traps for insects underground.
Drori is the author of two acclaimed books, Around the World in 80 Plants and Around the World in 80 Trees.
