What flower once caused the Dutch economy to crash?

When the tulip flower was imported to Holland from Turkey in the late 16th century, the Dutch enthusiasm for the flower caused a dramatic price inflation that eventually crashed, creating an economic bubble situation that had a wide-ranging impact in the Dutch economy during the 17th century. Prices for tulips had become so great that a single bulb could sell for more than a working-class individual would take home in a year.

Like other economic bubble situations, the tulip bubble bust caused great financial loss to speculative investors. This financial impact reverberated through Dutch society at the time, causing an economic depression that helped to kick off a general Dutch distaste for speculation.
