Tulip Test Gardens
What factors contribute to the timing of emerging tulips? Is it latitude? Elevation? Distance from the oceans? Or, is it a combination of factors? Students compare their own garden profile with gardens planted across the Northern Hemisphere to learn more about plants, climate, and seasons.

"We were all shocked to see one little tulip sprout coming through the ground today. We can't wait to check for more each day!!"
