Results
The results were that the flowers did Chang the color of the food coloring.

Why did it change color?
Most plants drink water from the ground through their roots. The water travels up the stem of the plant into the leaves where it makes food. When a flower is cut, it no longer has its roots, but the stem of the flower still drinks up the water and provides it to the leaves and flowers. Which changes the color of the flower.

Conclusion
Our Hypothesis was wrong the flowers did change color after all.
