Tulips in Michigan, particularly in Holland, typically bloom from late April through mid-May. The peak blooming period usually coincides with the annual Tulip Time Festival, which runs around early May (for example, May 2-11 in 2025). The bloom time can vary slightly depending on the weather, with cooler temperatures potentially delaying the blooms and warmer weather bringing them earlier. The city also strategically plants a variety of tulip types that bloom early, mid, and late season to ensure a cascading bloom throughout this period. Tulips are planted in the fall before the ground freezes to bloom in spring.
