Tracking Change in Seasons and Climate Around the Globe
This past fall, people across the northern hemisphere planted Red Emperor tulip bulbs in Journey North Test Gardens to monitor seasonal change in a scientific way. This spring, when plants emerge and bloom, test gardeners will report their observations and data. One garden at a time, the relationship between climate, geography, and the arrival of spring is revealed.

Join the Fun!
Spring arrives at different times in different places around the globe. Observe seasonal change and predict when spring will reach your hometown by following news updates and exploring real-time maps. Local climate affects where, when, and how plants grow. As tulip test gardens emerge and bloom, discover how season-driven weather and climate factors influence plant growth.

Journey North keeps garden observations in a permanent database. With longterm data, important scientific questions can be explored: How do the Earth's different climate conditions affect plant growth? What patterns do the data reveal? Are variations normal? How does this spring compare with previous years?
