Flowers are famous for their smells. Most are sweet, but a few are downright stinky. Either way, the science of how and why they make these scents is fascinating. Join Molly and co-host Isla as they learn about pollinators, flower smells and the mighty corpse flower! Plus a smell for your ears: the Mystery Sound!

Guest: Dr Kelsey Byers, evolutionary chemical ecologist and group leader at the John Innes Center.
