There Never Was a Real Tulip Fever | History | SmithsonianThe Dutch learned that tulips could be grown from seeds or buds that grew on the mother bulb; a bulb that grows from seed would take 7 to 12 years before flowering, but a bulb itself could flower the very next year. Of particular interest to Clusius and other tulip traders were “broken bulbs”—tulips whose petals showed a striped, multicolor pattern rather than a single solid color. The effect was unpredictable, but the growing demand for these rare, “broken bulb” tulips led naturalists to study ways to reproduce them. (The pattern was later discovered to be the result of a mosaic virus that actually makes the bulbs sickly and less likely to reproduce.) “The high market price for tulips to which the current version of tulipmania refers were prices for particularly beautiful broken bulbs,” writes economist Peter Garber. “Since breaking was unpredictable, some have characterized tulipmania among growers as a gamble, with growers vying to produce better and more bizarre variegations and feathering.” After all the money Dutch speculators spent on the bulbs, they only produced flowers for about a week—but for tulip lovers, that week was a glorious one. “As luxury objects, tulips fit well into a culture of both abundant capital and new cosmopolitanism,” Goldgar writes. Tulips required expertise, an appreciation of beauty and the exotic, and, of course, an abundance of money.
