Author, plant lover and former BBC documentary maker Jonathan Drori joins the show for a chat about recent botanical news.
This week, experts from Cambridge University look set to save the humble banana from extinction after developing a technique to graft different species of the fruit together, something previously thought impossible. And a mignonette leek orchid, which was last documented in 1933, has been rediscovered in Australia - which is home to approximately 1550 species of Orchidaceae.
Drori is the author of Around the World in 80 Trees and Around the World in 80 Plants.
