Tulips Blooming in Spring

Pella Tulip Time is planned in advance to make sure that tulips are properly prepared and planted. Every year the tulips bloom at different times due to changes in the climate such as soil temperature and precipitation. Some years tulips bloom ahead of schedule or after the event.  In 2021, Tulip Time was scheduled May 7-8 but in by April 17, a majority of the tulips were already in full bloom. 

Possible Guiding, Compelling and/or Anchoring Questions

  • What conditions must take place for blooming to occur?
  • Why would tulips bloom early?
  • Why would tulips bloom late?
  • When would we plant tulips?
  • How would dry/wet conditions change blooming conditions? How would a warm winter change the blooming of tulips?
  • Why do different varieties of tulips bloom at different times?

Classroom Suggestions

  • Build a model of a tulip’s life cycle over a year.
  • Research optimal growing conditions for tulips including soil temperature, soil characteristics, precipitation and shade.
  • Make a claim using soil temperature and the blooming of tulips together.
  • Research other plants that grow similarly and plants that can not grow in Iowa due to climate. 
  • Research multiple varieties of tulips and when they bloom.
