Tulip Mania: Most of What You Have Heard Did Not Happen

Where the story we tell comes from

The popular version does not come from the 1630s. It comes from a book published in 1841, Charles Mackay's account of popular delusions, which is a wonderful read and a poor source. Mackay drew heavily on satirical pamphlets written at the time by moralists who disapproved of the trade, which is roughly like reconstructing an event from the editorials attacking it.

Those pamphlets were making a point about greed, not keeping records. The anecdotes that survive best are the ones that made the point best, which is exactly the selection effect you would expect.

What the records actually show

Prices genuinely did reach extraordinary levels for a small number of rare bulbs, and they genuinely did collapse in February 1637. That much holds up.

What does not hold up is almost everything else:

The country was not ruined. There is no measurable effect on the Dutch economy, which carried on being among the strongest in Europe.
There was no wave of bankruptcies or suicides. Those come from moralizing pamphlets, not from records.
The sailor who ate a priceless bulb thinking it was an onion appears to be an invention.
It was not a national mania. The trade involved a fairly small number of people in a handful of towns.

The people involved were largely craftsmen and merchants who could afford to lose the money, and a good number of them were trading with each other rather than with the wider public.

Much of the trade was also not what we would now call trade. A great deal of it happened in taverns, in winter, when the bulbs were in the ground and could not be delivered or inspected. Buyers were agreeing to purchase in the summer at a price fixed now. When the market broke, many of those contracts were simply not enforced, and the courts largely declined to help either side. People who had agreed to pay a fortune mostly did not end up paying it.

The part that is genuinely strange

The bulbs that reached the silly prices were not ordinary tulips. They were the broken ones: flowers with feathered and flamed streaks of color running through the petals, each one unrepeatable, and impossible to produce reliably from seed.

Nobody at the time knew why it happened. Growers understood only that a plain bulb sometimes broke into a patterned one, and that the pattern then passed to its offsets, which is why a single bulb could be worth so much. It was not until the twentieth century that the cause was identified as a virus, spread by aphids, which disrupts the pigment in the petal.

So the most valuable flowers in Europe were the sick ones, and the thing that made them beautiful was the thing slowly weakening the plant. Infected bulbs produce fewer and smaller offsets each generation, which is a large part of why they stayed scarce. The famous broken tulips of the Dutch still life paintings essentially no longer exist. The striped tulips sold today are bred to look like them and are perfectly healthy.

Why it matters beyond being a good story

The tulip is worth knowing about because it is the first flower that was treated as a commodity rather than as a garden plant, and the Dutch flower trade that grew out of that period never went away. Four hundred years later the Netherlands still moves an enormous share of the world's cut flowers and bulbs, and the auction system that does it is a direct descendant of the market that supposedly ruined the country.

It did not ruin the country. It built an industry that is still running.
