The Garden: Why are flowers a biological mystery?

Last week I gave an online talk for The Garden, a new a platform that connects people who love to learn with academics and experts for live talks. I spoke on Darwin’s abominable mystery, covering 150 years of research on the origin of the flowering plants. This drew on articles I have published in American Journal of Botany and Nature Plants. Intriguingly, the mystery is still unsolved. My talk is now available on-demand here. You have to register to watch, but (for now) registration is free.
