THE SCIENCE OF COLOR CHANGING FLOWERS The cut flowers take up water through their stem and the water moves from the stem to the flowers and leaves. Water travels up tiny tubes in the plant by a process called Capillary Action. Putting a colored dye in the water in the vase allows us to observe capillary action at work.

What is the purpose of the color changing flower experiment?

The second type of color change is due to the fact many roses are grafted, so the branches are one variety and the lower root system is a hardier rose.

Unlike the water, however, food coloring cannot evaporate. This means the food coloring can enter the plant but cannot leave it. Because the food coloring is non-toxic, this does not kill the plant, but it definitely does color the plant.

Can a white dogwood turn pink?
A: It's not terribly unusual for a white-flowering dogwood to pop out a limb that has pink flowers. Growers select just such limbs in a nursery, graft them to the trunks of small white-flowered dogwoods and thereby make pink-flowered dogwoods to sell to gardeners.
