In this episode we journey back to 17th century Holland where the locals have gone crazy about flowers -- tulips, to be precise -- and are trading them for crazy sums of money. We look at what actually happened and whether things really were as nutty as the popular story holds, and discover that while there is a grain of truth lurking in the flowerbeds of the Dutch Republic, it's all a bit more complicated than that. On the way to a conclusion, we learn about tulip horticulture, living conditions at the time, and the beginnings of an early modern financial system. And, of course, we see how the lure of leverage was as irresistible 400 years ago as it is today.
