Citizen scientists plant tulip test gardens in places with different climates. Explore climate variables to predict how different conditions will affect where and when tulips emerge and bloom.

Sunny or shady? Wet or dry? Windy or calm? Plants respond to the climate where they are growing. Microclimate refers to the climate conditions of a small, specific place, where conditions may differ from those of the larger surrounding space. Explore conditions that create microclimates. Try the Microclimate Challenge: Plant tulip bulbs in microclimates with contrasting conditions to discover how climate affects plant growth.
