Have you ever seen tulips with vibrant colors and patterns? In fact, viral infections cause these beautiful blooms. Tulips are introduced to specific viruses and each one causes a unique reaction.

This experiment shows where the water goes when you water a plant and how vital stem functions are to plant growth. As the carnation absorbs the colored water, you can visibly see how the water moves through the flower. The white carnation petals will change color to match whatever the color of the water.

Only one plant can be manipulated to change blossom color while it's growing. Big-leaf hydrangeas Hydrangea macrophylla stand alone in their ability to change bloom color in response to soil conditions. They thrive in U. Department of Agriculture plant hardiness zones 6 through 9. In acidic soil, which has a pH below 5. In soils with neutral or alkaline pH of 6. Soil pH in between those numbers can cause the plant to produce lavender flowers, or even blue and pink blooms on the same plant.

The specific cultivar of big leaf hydrangea also affects bloom color. Certain flowers change color naturally. The "Confederate rose," Hibiscus mutabilis is a fine example.

When the blossoms first open in the morning they're very pale, almost white, but their color deepens through pink to a bright, bold red as the day comes to a close and they reach the end of their lifespan.
