Tulipomania, or the obsession with tulips, is something that demonstrates the desire for beauty within humans through the constant search and quest of humans to breed and create other types of tulip, in all sorts of different colours and variegated patterns. The difficulties of growing a particular type or colour of tulip meant that in the past tulips were highly prized flowers, and at various points in history, in particular between the years of 1634 and 1637, they were hotly traded. Pollen argues that tulips were so popular in the Netherlands because of the bleakness of the Dutch landscape and the way that there was little colour or vibrancy in the local flora and fauna:
...what beauty there is in the Netherlands is largely the result of human effort…
This meant that beauty in the form of the tulip, which was a real result of human effort, became greatly prized and was overvalued, particularly during the three years quoted above. The long, lengthy process by which tulips of a particular colour could be grown meant that these flowers, which were Turkish originally, satisfied the human desire for beauty through labour and unstinting effort.
