I think I’m coming down with galanthomania. It’s a rare affliction, but one that’s hard to shake, and it’s affecting more people every year. Galanthus are snowdrops, and galanthomania is a 21st-century version of that 17th-century craze for tulips which began in the Dutch golden age. At the height of the tulip mania some bulbs were selling at 3,000 or 4,000 florins, almost ten times a craftsman’s annual wage.
